为什么保持好睡眠的原因英语作文
为什么保持好睡眠的原因英语作文The Importance of Getting Enough SleepSleep is one of the most important things for kids like me. It helps our bodies and minds grow big and strong! When I don't get enough sleep, I feel grumpy, tired, and have a hard time paying attention in class. That's why it's so important for all of us to make sure we get plenty of sleep every single night.There are so many amazing reasons why we need sleep. First of all, sleep is great for our brains! While we're sleeping, our brains are hard at work, sorting through all the things we learned that day. Sleep helps strengthen our memories by reinforcing the new knowledge we gained. It's like a student going over their notes before a big test - except our brains do this automatically while we snooze!Sleep also gives our brain cells a chance to recharge their batteries. During the day, our brain cells work really hard processing information, thinking, and helping our bodies move around. When we sleep, those little brain cell batteries can refuel so they have enough energy to power us through another busy day.Not only is sleep amazing for our brains, but it's also crucial for our bodies to grow and develop properly. That's because sleep is the time when our bodies release hormones that help us grow taller and build stronger muscles and bones. Kids who don't get enough sleep can end up being shorter than they could have been. No one wants that!Getting enough ZZZs also keeps our immune systems, which fight off sickness, working in tip-top shape. When we're sleep deprived, our bodies have a harder time battling germs and viruses that cause colds, flu, and other nasty illnesses. With plenty of sleep, our immune system soldier cells can stay strong and protect us.Lack of sleep can even make it harder for our bodies to heal from injuries like cuts, bruises, or broken bones. While we're sleeping, our bodies get busy repairing damaged cells and tissues. It's like giving our bodies the time and energy they need to work on those self-repair projects.As if all those reasons weren't enough, sleep also plays a big role in maintaining a healthy weight. Studies show that kids who don't get sufficient sleep tend to weigh more than those who do. Sleep helps control the hormones that make us feel hungry orfull, so a good night's rest means we're less likely to overeat the next day.With adequate sleep, we also tend to have more energy to run around, play sports, and just be active in general. And being active keeps our hearts strong and bodies fit! Tired, cranky kids are more likely to just slouch on the couch instead of getting out and breaking a sweat.Finally, sleep is absolutely essential for concentration, attention, and learning. Sleepy kids have such a hard time focusing on their schoolwork. Their minds wander, they get distracted easily, and they just can't take in new information as well. A well-rested brain is a brain that's ready to learn and soak up lots of fascinating knowledge!So as you can see, there are a million and one reasons why getting our ZZZs each night is so crucial for growing kids. Sleep powers our minds, builds our bodies, keeps us healthy, helps us pay attention, and so much more. It's like a magical elixir that lets us be the best versions of ourselves!Of course, getting enough sleep isn't always easy. Maybe you get cranky at bedtime like I sometimes do. Or perhaps you struggle to fall asleep because your mind is buzzing with thoughts about all the fun you had that day. Bedtime routineswith calming activities like reading books or taking a warm bath can help signal to our bodies that it's time to wind down.Setting a regular sleep schedule is key too. Our bodies just work better when we go to bed and wake up around the same times each day. That's because we have internal "body clocks" that determine when we naturally start to feel tired and when we're ready to wake up.Our parents and teachers are always reminding us how important sleep is for a reason! When we make getting zzzzufficient sleep a priority, we're giving our growing minds and bodies the TLC they need to develop into their very best. So tonight, let's all dream big by getting those zzzzzzzs!。

TED英语演讲稿:我们为什么要睡觉简介:一生中,我们有三分之一的时间都在睡眠中度过。
关于睡眠,你又了解多少?睡眠专家russell foster为我们解答为什么要睡觉,以及睡眠对健康的影响。
what i'd like to do today is talk about one of my favorite subjects, and that is the neuroscience of sleep.now, there is a sound -- (alarm clock) -- aah, it worked -- a sound that is desperately, desperately familiar to most of us, and of course it's the sound of the alarm clock. and what that truly ghastly, awful sound does is stop the single most important behavioral experience that we have, and that's sleep. if you're an average sort of person, 36 percent of your life will be spent asleep, which means that if you live to 90, then 32 years will have been spent entirely asleep.now what that 32 years is telling us is that sleep at some level is important. and yet, for most of us, we don't give sleep a second thought. we throw it away. we really just don't think about sleep. and so what i'd like to do today is change your views, change your ideas and your thoughts about sleep. and the journey that i want to take you on, we need to start by going back in time."enjoy the honey-heavy dew of slumber." any ideas who said that? shakespeare's julius caesar. yes, let me give you a few more quotes. "o sleep, o gentle sleep, nature's soft nurse, how have i frighted thee?" shakespeare again, from -- i won't say it -- the scottish play. [correction: henry iv, part 2] (laughter) from the same time: "sleep is the golden chain that ties health and our bodies together." extremely prophetic, by thomas dekker, another elizabethan dramatist.but if we jump forward 400 years, the tone about sleepchanges somewhat. this is from thomas edison, from the beginning of the 20th century. "sleep is a criminal waste of time and a heritage from our cave days." bang. (laughter) and if we also jump into the 1980s, some of you may remember that margaret thatcher was reported to have said, "sleep is for wimps." and of course the infamous -- what was his name? -- the infamous gordon gekko from "wall street" said, "money never sleeps."what do we do in the 20th century about sleep? well, of course, we use thomas edison's light bulb to invade the night, and we occupied the dark, and in the process of this occupation, we've treated sleep as an illness, almost. we've treated it as an enemy. at most now, i suppose, we tolerate the need for sleep, and at worst perhaps many of us think of sleep as an illness that needs some sort of a cure. and our ignorance about sleep is really quite profound.why is it? why do we abandon sleep in our thoughts? well, it's because you don't do anything much while you're asleep, it seems. you don't eat. you don't drink. and you don't have sex. well, most of us anyway. and so therefore it's -- sorry. it's a complete waste of time, right? wrong. actually, sleep is an incredibly important part of our biology, and neuroscientists are beginning to explain why it's so very important. so let's move to the brain.now, here we have a brain. this is donated by a social scientist, and they said they didn't know what it was, or indeed how to use it, so -- (laughter) sorry. so i borrowed it. i don't think they noticed. okay. (laughter)the point i'm trying to make is that when you're asleep, this thing doesn't shut down. in fact, some areas of the brain areactually more active during the sleep state than during the wake state. the other thing that's really important about sleep is that it doesn't arise from a single structure within the brain, but is to some extent a network property, and if we flip the brain on its back -- i love this little bit of spinal cord here -- this bit here is the hypothalamus, and right under there is a whole raft of interesting structures, not least the biological clock. the biological clock tells us when it's good to be up, when it's good to be asleep, and what that structure does is interact with a whole raft of other areas within the hypothalamus, the lateral hypothalamus, the ventrolateral preoptic nuclei. all of those combine, and they send projections down to the brain stem here. the brain stem then projects forward and bathes the cortex, this wonderfully wrinkly bit over here, with neurotransmitters that keep us awake and essentially provide us with our consciousness. so sleep arises from a whole raft of different interactions within the brain, and essentially, sleep is turned on and off as a result of a range ofokay. so where have we got to? we've said that sleep is complicated and it takes 32 years of our life. but what i haven't explained is what sleep is about. so why do we sleep? and it won't surprise any of you that, of course, the scientists, we don't have a consensus. there are dozens of different ideas about why we sleep, and i'm going to outline three of those.the first is sort of the restoration idea, and it's somewhat intuitive. essentially, all the stuff we've burned up during the day, we restore, we replace, we rebuild during the night. and indeed, as an explanation, it goes back to aristotle, so that's, what, 2,300 years ago. it's gone in and out of fashion. it's fashionable at the moment because what's been shown is that within the brain, awhole raft of genes have been shown to be turned on only during sleep, and those genes are associated with restoration and metabolic pathways. so there's good evidence for the whole restoration hypothesis.what about energy conservation? again, perhaps intuitive. you essentially sleep to save calories. now, when you do the sums, though, it doesn't really pan out. if you compare an individual who has slept at night, or stayed awake and hasn't moved very much, the energy saving of sleeping is about 110 calories a night. now, that's the equivalent of a hot dog bun. now, i would say that a hot dog bun is kind of a meager return for such a complicated and demanding behavior as sleep. so i'm less convinced by the energy conservation idea.but the third idea i'm quite attracted to, which is brain processing and memory consolidation. what we know is that, if after you've tried to learn a task, and you sleep-deprive individuals, the ability to learn that task is smashed. it's really hugely attenuated. so sleep and memory consolidation is also very important. however, it's not just the laying down of memory and recalling it. what's turned out to be really exciting is that our ability to come up with novel solutions to complex problems is hugely enhanced by a night of sleep. in fact, it's been estimated to give us a threefold advantage. sleeping at night enhances our creativity. and what seems to be going on is that, in the brain, those neural connections that are important, those synaptic connections that are important, are linked and strengthened, while those that are less important tend to fade away and be less important.okay. so we've had three explanations for why we might sleep, and i think the important thing to realize is that the details willvary, and it's probable we sleep for multiple different reasons. but sleep is not an indulgence. it's not some sort of thing that we can take on board rather casually. i think that sleep was once likened to an upgrade from economy to business class, you know, the equiavlent of. it's not even an upgrade from economy to first class. the critical thing to realize is that if you don't sleep, you don't fly. essentially, you never get there, and what's extraordinary about much of our society these days is that we are desperately sleep-deprived.so let's now look at sleep deprivation. huge sectors of society are sleep-deprived, and let's look at our sleep-o-meter. so in the 1950s, good data suggests that most of us were getting around about eight hours of sleep a night. nowadays, we sleep one and a half to two hours less every night, so we're in the six-and-a-half-hours-every-night league. for teenagers, it's worse, much worse. they need nine hours for full brain performance, and many of them, on a school night, are only getting five hours of sleep. it's simply not enough. if we think about other sectors of society, the aged, if you are aged, then your ability to sleep in a single block is somewhat disrupted, and many sleep, again, less than five hours a night. shift work. shift work is extraordinary, perhaps 20 percent of the working population, and the body clock does not shift to the demands of working at night. it's locked onto the same light-dark cycle as the rest of us. so when the poor old shift worker is going home to try and sleep during the day, desperately tired, the body clock is saying, "wake up. this is the time to be awake." so the quality of sleep that you get as a night shift worker is usually very poor, again in that sort of five-hour region. and then, of course, tens of millions of people suffer from jet lag. so who here has jet lag? well, my goodness gracious. well,thank you very much indeed for not falling asleep, because that's what your brain is craving.one of the things that the brain does is indulge in micro-sleeps, this involuntary falling asleep, and you have essentially no control over it. now, micro-sleeps can be sort of somewhat embarrassing, but they can also be deadly. it's been estimated that 31 percent of drivers will fall asleep at the wheel at least once in their life, and in the u.s., the statistics are pretty good: 100,000 accidents on the freeway have been associated with tiredness, loss of vigilance, and falling asleep. a hundred thousand a year. it's extraordinary. at another level of terror, we dip into the tragic accidents at chernobyl and indeed the space shuttle challenger, which was so tragically lost. and in the investigations that followed those disasters, poor judgment as a result of extended shift work and loss of vigilance and tiredness was attributed to a big chunk of those disasters.so when you're tired, and you lack sleep, you have poor memory, you have poor creativity, you have increased impulsiveness, and you have overall poor judgment. but my friends, it's so much worse than that.(laughter)if you are a tired brain, the brain is craving things to wake it up. so drugs, stimulants. caffeine represents the stimulant of choice across much of the western world. much of the day is fueled by caffeine, and if you're a really naughty tired brain, nicotine. and of course, you're fueling the waking state with these stimulants, and then of course it gets to 11 o'clock at night, and the brain says to itself, "ah, well actually, i need to be asleep fairly shortly. what do we do about that when i'm feeling completely wired?" well, of course, you then resort to alcohol. now alcohol,short-term, you know, once or twice, to use to mildly sedate you, can be very useful. it can actually ease the sleep transition. but what you must be so aware of is that alcohol doesn't provide sleep, a biological mimic for sleep. it sedates you. so it actually harms some of the neural proccessing that's going on during memory consolidation and memory recall. so it's a short-term acute measure, but for goodness sake, don't become addicted to alcohol as a way of getting to sleep every night.another connection between loss of sleep is weight gain. if you sleep around about five hours or less every night, then you have a 50 percent likelihood of being obese. what's the connection here? well, sleep loss seems to give rise to the release of the hormone ghrelin, the hunger hormone. ghrelin is released. it gets to the brain. the brain says, "i need carbohydrates," and what it does is seek out carbohydrates and particularly sugars. so there's a link between tiredness and the metabolic predisposition for weight gain.stress. tired people are massively stressed. and one of the things of stress, of course, is loss of memory, which is what i sort of just then had a little lapse of. but stress is so much more. so if you're acutely stressed, not a great problem, but it's sustained stress associated with sleep loss that's the problem. so sustained stress leads to suppressed immunity, and so tired people tend to have higher rates of overall infection, and there's some very good studies showing that shift workers, for example, have higher rates of cancer. increased levels of stress throw glucose into the circulation. glucose becomes a dominant part of the vasculature and essentially you become glucose intolerant. therefore, diabetes 2. stress increases cardiovascular disease as a result of raising blood pressure. so there's a whole raft of thingsassociated with sleep loss that are more than just a mildly impaired brain, which is where i think most people think that sleep loss resides.so at this point in the talk, this is a nice time to think, well, do you think on the whole i'm getting enough sleep? so a quick show of hands. who feels that they're getting enough sleep here? oh. well, that's pretty impressive. good. we'll talk more about that later, about what are your tips.so most of us, of course, ask the question, "well, how do i know whether i'm getting enough sleep?" well, it's not rocket science. if you need an alarm clock to get you out of bed in the morning, if you are taking a long time to get up, if you need lots of stimulants, if you're grumpy, if you're irritable, if you're told by your work colleagues that you're looking tired and irritable, chances are you are sleep-deprived. listen to them. listen to yourself.what do you do? well -- and this is slightly offensive -- sleep for dummies: make your bedroom a haven for sleep. the first critical thing is make it as dark as you possibly can, and also make it slightly cool. very important. actually, reduce your amount of light exposure at least half an hour before you go to bed. light increases levels of alertness and will delay sleep. what's the last thing that most of us do before we go to bed? we stand in a massively lit bathroom looking into the mirror cleaning our teeth. it's the worst thing we can possibly do before we went to sleep. turn off those mobile phones. turn off those computers. turn off all of those things that are also going to excite the brain. try not to drink caffeine too late in the day, ideally not after lunch. now, we've set about reducing light exposure before you go to bed, but light exposure in the morning is very good at setting thebiological clock to the light-dark cycle. so seek out morning light. basically, listen to yourself. wind down. do those sorts of things that you know are going to ease you off into the honey-heavy dew of slumber.okay. that's some facts. what about some myths?teenagers are lazy. no. poor things. they have a biological predisposition to go to bed late and get up late, so give them a break.we need eight hours of sleep a night. that's an average. some people need more. some people need less. and what you need to do is listen to your body. do you need that much or do you need more? simple as that.old people need less sleep. not true. the sleep demands of the aged do not go down. essentially, sleep fragments and becomes less robust, but sleep requirements do not go down.and the fourth myth is, early to bed, early to rise makes a man healthy, wealthy and wise. well that's wrong at so many different levels. (laughter) there is no, no evidence that getting up early and going to bed early gives you more wealth at all. there's no difference in socioeconomic status. in my experience, the only difference between morning people and evening people is that those people that get up in the morning early are just horribly smug.(laughter) (applause)okay. so for the last part, the last few minutes, what i want to do is change gears and talk about some really new, breaking areas of neuroscience, which is the association between mental health, mental illness and sleep disruption. we've known for 130 years that in severe mental illness, there is always, always sleep disruption, but it's been largely ignored. in the 1970s, whenpeople started to think about this again, they said, "yes, well, of course you have sleep disruption in schizophrenia because they're on anti-psychotics. it's the anti-psychotics causing the sleep problems," ignoring the fact that for a hundred years previously, sleep disruption had been reported before anti-psychotics.so what's going on? lots of groups, several groups are studying conditions like depression, schizophrenia and bipolar, and what's going on in terms of sleep disruption. we have a big study which we published last year on schizophrenia, and the data were quite extraordinary. in those individuals with schizophrenia, much of the time, they were awake during the night phase and then they were asleep during the day. other groups showed no 24-hour patterns whatsoever. their sleep was absolutely smashed. and some had no ability to regulate their sleep by the light-dark cycle. they were getting up later and later and later and later each night. it was smashed.so what's going on? and the really exciting news is that mental illness and sleep are not simply associated but they are physically linked within the brain. the neural networks that predispose you to normal sleep, give you normal sleep, and those that give you normal mental health are overlapping. and what's the evidence for that? well, genes that have been shown to be very important in the generation of normal sleep, when mutated, when changed, also predispose individuals to mental health problems. and last year, we published a study which showed that a gene that's been linked to schizophrenia, which, when mutated, also smashes the sleep. so we have evidence of a genuine mechanistic overlap between these two important systems.other work flowed from these studies. the first was that sleepdisruption actually precedes certain types of mental illness, and we've shown that in those young individuals who are at high risk of developing bipolar disorder, they already have a sleep abnormality prior to any clinical diagnosis of bipolar. the other bit of data was that sleep disruption may actually exacerbate, make worse the mental illness state. my colleague dan freeman has used a range of agents which have stabilized sleep and reduced levels of paranoia in those individuals by 50 percent.so what have we got? we've got, in these connections, some really exciting things. in terms of the neuroscience, by understanding the neuroscience of these two systems, we're really beginning to understand how both sleep and mental illness are generated and regulated within the brain. the second area is that if we can use sleep and sleep disruption as an early warning signal, then we have the chance of going in. if we know that these individuals are vulnerable, early intervention then becomes possible. and the third, which i think is the most exciting, is that we can think of the sleep centers within the brain as a new therapeutic target. stabilize sleep in those individuals who are vulnerable, we can certainly make them healthier, but also alleviate some of the appalling symptoms of mental illness.so let me just finish. what i started by saying is take sleep seriously. our attitudes toward sleep are so very different from a pre-industrial age, when we were almost wrapped in a duvet. we used to understand intuitively the importance of sleep. and this isn't some sort of crystal-waving nonsense. this is a pragmatic response to good health. if you have good sleep, it increases your concentration, attention, decision-making, creativity, social skills, health. if you get sleep, it reduces your mood changes, your stress, your levels of anger, your impulsivity, and your tendencyto drink and take drugs. and we finished by saying that an understanding of the neuroscience of sleep is really informing the way we think about some of the causes of mental illness, and indeed is providing us new ways to treat these incredibly debilitating conditions.jim butcher, the fantasy writer, said, "sleep is god. go worship." and i can only recommend that you do the same.thank you for your attention.(applause)。

TED--一定要睡个好觉(英文)
TED--一定要睡个好觉(英文)Sleep, it’s something we spend about a third of our lives doing, but do any of us really understand what it’s all about? Two thousand years ago, Galan, one of the most prominent medical researchers of the ancient world, proposed that while we‘re awake, our brain’s motive force, it’s juice, would flow out to all the other parts of the body, animating them but leaving the brain all dried up, and he thought when we sleep, all this moisture that filled the rest of the body would come rushing back, rehydrating the brain and refreshing the mind.Now, that sounds completely ridiculous to us now, but Galan was simply trying to explain something about sleep that we are deal with every day. See, we all know based on our own experience that when you sleep, it clears your mind, and when you don’t sleep, it leaves your mind murky. But while we know a great deal more about sleep now than when Galen was around, we still haven’t understood why it’s that sleep, of all of our activities, has this incredible restorative function for the mind. So today I want to tell you about some recent research that may shed new light on this question.We fund that sleep my actually be a kind of elegant design solution to some of the brain’s most basic needs, a unique way that the brain meets the high demands and the narrow margins that set it apart from all the other organs of the body. So almost all the biology that we observe can be thought of as a series of problems and their corresponding solutions, and first problemthat every organ must solve is a continuous supply of the nutrients to fuel all those cells of the body. In the brain, that is especially critical; its intense electrical activity uses up a quarter of the body’s entire energy supply, even though the brain accounts for only about two percent of the body’s mass. So the circulatory system solves the nutrient delivery problem by sending blood vessels to supply nutrients and oxygen to every corner of our body. You actually see it in this video here. Here, we’re imaging blood vessels in the brain of a living mouse. The blood vessel form a complex network that feels the entire brain volume. They start at the surface of the brain, and then they dive down into the issue itself, and as they spread out, they supply nutrients and oxygen to each and every cells in the brain.Now, just as every cell requires nutrients to fuel it, every cell also produces waste as a byproduct, and the clearance of that waste is the second basic problem that each organ has to solve. This diagram shows the body’s lymphatic system, which has involved to meet this need. It‘s a second parallel network of vessels that extend throughout the body. It takes up proteins and other waste from the spaces between the cells, it collects them, and then dumps them into the blood so they can be disposed of.But if you look really closed at this diagram, you’ll see something that doesn’t make a lot sense. So if we were to zoom into this g uy’s head, one of the things that you would see there is that there are no lymphatic vessels in the brain. But that doesn’t make a lot of sense, does it? I mean, the brain is this intensely active organ that produces a correspondingly large amount of waste that must be efficiently cleared. And yet, it lackslymphatic vessels, which means that the approach that takes to clearing away its waste won’t work in the brain. So how, then, does the brain solve its waste clearance problem? Well, that seemingly mundane question is where our group first jumped into this story, and what we found as we dove down into the brain, down among the neurons and the blood vessels, was that the brain’ s solution to the problem of the waste clearance, it was really unexpected. It was ingenious, but it was also beautiful.Let me tell you about what we found. So the brain has this large pool of clean, clear fluid called cerebrospinal fluid. We call it the CSF. The CSF fills the space that surrounds the brain, and wastes from inside the brain make their way out to the CSF, which gets dumped, along with the waste into the blood. So in that way, it sounds a lot like the lymphatic system, doesn’t it? But what’s interesting is that the fluid and the waste from inside the brain, they don’t just percolate their way randomly out to these pools of the CSF. Instead, there is a specialized network of plumbing that organizes and facilities this process.You can see that in these videos. Here, we‘re again imaging into the brain of living mice. The frame on your left shows what’s happening at the brain’s surface, and the frame on your right shows what’s happening down below the surface of the brain within the tissue itself. We’ve labeled the blood vessels in red, and the CSF that’s surrounding the b rain will be green. Now, what was surprising to us was that the fluid on the outside of the brain, it didn’t stay on the outside. Instead, the CSF was pumped back into and through the brain along the outsides of the blood vessels, and as it flushed down into the brain along the outsidesof these vessels, it was actually helping to clear away, to clean the waste from the spaces between the brain’s cells. If you think about it, using the outsides of these blood vessels like this is a really clever design solution, because the brain is enclosed in a rigid skull and it’s packed full of cells, so there is no extra space inside it for a whole second set of vessels like the lymphatic system. Yet the blood vessels, they extend from the surface of the brain down to reach every single cell in the brain, which means that fluid that‘s traveling along the outsides of these vessels can gain easy access to the entire brain’s volume, so it’s actually this really clever way to repurpose one set of vessels, the blood vessels, to take over and replace the function of a second set of vessels, the lymphatic vessels, to make it so you don’t need them.And what’s amazing is that no other organ takes quiet this approach to clearing away the waste from between its cells. This is a solution that is entirely unique to the brain. But our most surprising finding was that all of this, everything I just told you about, with all this fluid rushing through the brain, it’s only happening in the sleeping brain. Here, the video on the left shows how much of the CSF is moving through the brain of a living mouse while it’s awake. It’s almost nothing. Yet in the same animal, if we just wait just a little while until it’s gone to sleep, what we see is that the CSF is rushing through the brain, and we discovered that at the same time when the brain goes to sleep, the brain cells themselves seem to shrink, opening up spaces in between them, allowing fluid to rush through and allowing waste to be cleared out.So it seems that Galen may actually have been sort of the right track when he wrote about fluid rushing through the brain when sleep came on. Our own research, now it’s 2000 years later, suggesting that what’s happening is that when the brain is awake and is at its most busy, it puts off clearing away the waste from the spaces between its cells until later, and then, when it goes to sleep and doesn’t have to be as busy, it shifts into a kind of clearing mode to clean away the waste from the spaces between it cells, the waste that’s accumulated thro ughout the day. So it’s actually a little bit like how you or I, we put off our household chores during the work week when we don’t have time to get to do it, and then we play catch up on all the cleaning that we have to do when the weekends rolls around.Now, I’ve just talked a lot about waste clearance, but I haven’t been very specific about the kinds of waste that the brain needs to be clearing during sleep in order to stay healthy. The waste product that these recent studies focused most on is amyloid-beta, which is a protein that’s made in the brain all the time. My brain’s making amyloid-beta right now, and so is yours. But in patients with Alzheimer’s disease, amyloid-beta builds up and aggregates in the spaces between the brain’s cells, instead of b eing cleared away like it’s supposed to be, and it’s this buildup of amyloid-beta that’s thought to be one of the key steps in the development of that terrible disease. So we measured how fast amyloid-beta is cleared from the brain when it’s awake versus when it’s asleep, and we found that indeed, the clearance of amyloid-beta is much more rapid from the sleeping brain. So if sleep, then, is part of the brain’s solution to the problem of the waste clearance, then this may dramaticallychange how we think about the relationship between sleep, amyloid-beta, and Alzheimer’ s disease.A series of recent clinical studies suggest that among patients who haven’t yet developed Alzheimer’s disease, worsening sleep quality and sleep duration are associated with a greater amount of amyloid-beta building up in the brain, and while it’s important to point out that these studies don’t prove that lack of sleep or poor sleep cause Alzheimer’s disease, they do suggest that the failure of the brain to keep its house clean by clearing away waste like amyloid-beta may contribute to the development of conditions like the Alzheimer’s. So what this new research tell us, then, is that the one thing that all of you already knew about sleep, that even Galen understood about sleep, that it refreshes and clears the mind, may actually be a big part of what sleep is all about.See, you and I, we go to sleep every single night, but our brains, they never rest. While our body is still and our mind is off walking in dreams somewhere, the elegant machinery of the brain is quietly hard at work cleaning and maintaining this unimaginably complex machine. Like our house work, it’s a dirty and thankless job, but it’s also important. In your house if you stop cleaning your kitchen for a month, your home will become completely unlivable very quickly. But in the brain, the consequences of falling behind may be much greater than the embarrassment of dirty countertops, because when it comes to cleaning the brain, it is the very health and function of the mind and the body that’s at stake, which is why understanding these very basic housekeeping functions of the brain today may becritical for preventing and treating disease of the mind tomorrow.Thank you.。

睡眠重要性英语演讲稿初一The Importance of Sleep。
Good morning, everyone. Today, I am going to talk about the importance of sleep.As we all know, sleep is essential for our health and well-being. It is a time for our bodies to rest and recharge, and it plays a crucial role in our overall health. Unfortunately, many people, especially young students like us, do not get enough sleep due to busy schedules, homework, and extracurricular activities.First and foremost, sleep is important for our physical health. During sleep, our bodies repair and regenerate tissues, muscles, and organs. It also helps to boost our immune system, making us less susceptible to illnesses. In addition, getting enough sleep can help to regulate our metabolism and maintain a healthy weight.Furthermore, sleep is vital for our mental health. When we sleep, our brains process and consolidate memories from the day. This is why a good night's sleep can improve our ability to focus, concentrate, and learn new information. On the other hand, lack of sleep can lead to irritability, mood swings, and difficulty in managing stress.Moreover, adequate sleep is crucial for our emotional well-being. It can help to regulate our emotions and improve our overall mood. On the other hand, chronic sleep deprivation can increase the risk of developing anxiety and depression.In conclusion, sleep is not a luxury, but a necessity. It is essential for our physical, mental, and emotional health. As young students, it is important for us to prioritize our sleep and make sure we are getting enough rest each night. By doing so, we can improve our overall health and well-being, and perform better in school and other activities.Thank you for listening.。
TED英语演讲稿:我们为什么要睡觉
TED英语演讲稿:我们为什么要睡觉Ladies and gentlemen,Today I would like to talk to you about something that we all do every day. It is something that we often take for granted, yet it is essential for our health and well-being. I am talking about sleep.Sleep is something that we all need, yet not all of us get enough of it. In today's society, we often prioritize other things over sleep, such as work, socializing, and entertainment. We think that we can function just fine on a few hours of sleep, but the reality is that we cannot. Our bodies need sleep to function properly, both physically and mentally.So why do we need sleep? The answer to that question is complex, but several factors come into play.The first factor is rest and restoration. When we sleep, our bodies get a chance to repair and restore themselves. Our muscles and tissues repair themselves, and we produce hormones that support growth and development. Without enough sleep, our bodies cannot perform these vital functions.The second factor is cognitive function. Sleep is essential for our brain function. When we sleep, our brains consolidate and process information that we learned during the day. This helps us to remember important things and learn new skills. Lack of sleep can lead to problems with memory, learning, and concentration.The third factor is emotional health. Sleep is necessary foremotional well-being. When we sleep, our brains process and regulate our emotions. Lack of sleep can lead to problems with emotional regulation, such as depression, anxiety, and irritability.Now that we know why we need sleep let's talk about how much sleep we actually need. The answer to that question varies depending on age, lifestyle, and individual needs. However, the general recommendation for adults is 7-9 hours of sleep per night. Children and teenagers may need more sleep, while older adults may need less.It is also important to note that the quality of our sleep is just as important as the quantity of our sleep. We need to ensure that we are getting enough deep sleep, which is the stage of sleep that is most restorative and beneficial for our bodies and minds.So what can we do to ensure that we are getting enough high-quality sleep? Here are a few tips:- Establish a bedtime routine and stick to it, even on weekends.- Create a sleep-conducive environment, which means eliminating noise, light, and distractions in the bedroom.- Avoid caffeine, alcohol, and heavy meals before bedtime.- Exercise regularly, but not too close to bedtime.- Practice relaxation techniques, such as deep breathing or meditation, to help you fall asleep.In conclusion, sleep is not a luxury; it is a necessity. We need sleep to function at our best physically and mentally. So let's make surethat we are prioritizing our sleep and giving our bodies the rest and restoration that they need. Thank you.。

与睡眠有关的英语演讲稿_与睡眠有关的英语演讲素材5篇睡觉,一般是指人类睡眠,是人类不可缺少的一种生理现象。
人的一生中,睡眠占了近1/3的时间,它的质量好坏与人体健康与否有密切关系,由此可见睡眠对每一个人是多么重要。

更多睡眠相关内容推荐↓↓↓能促进睡眠的故事世界睡眠日手抄报简单有助于睡眠的小故事科学的睡眠时间是怎样的什么是充足的睡眠与睡眠有关的英语演讲稿1With the College Entrance Examinations approaching , the students of Senior Three are focusing much more on studying. Many of them even begin to stay up studying. A heated discussion was held to argue about the advantages and disadvantages of it.Some students have their own reasons for studying late into night. Firstly, the quietness in the night will result in better effectiveness. Besides,the examinations are only 200 days away so its high time they made good use of every minute. What’s more, seeing others studying so hard, they will feel anxious if they don’t take action.Some others, however, hold the opposite view, saying that a sensible senior student must know how to balance his time between study and leisure. As everyone knows, staying up late will naturally affect the next days performance in class.As far as I’m concerned, different people have different habits. If you can hold it, it’s your own business when to study and when to sleep.与睡眠有关的英语演讲稿2Many people want to ask, what is the best time for sleep? Do we need to sleep early or late? My opinion is to sleep early. Here is the reason why we should sleep early. First, it will make you more healthy. Sleep late would cause illness, long time not sleeping early will damage your body. Second, many people had said that if you dont get many time to sleep, and you sleep late would make black rim of the eye. That is not healthy also, and its not beautiful. We should give our body a rest. Sleep is the best way. Well, there are certain time that is best for us to sleep. Sleep early is definitely better than sleep late. Also, we should not keep awake the whole night. You dont feel the damage when you are young, but when you get older, the problem start to appear. Many disease of heart and lung started from not sleep at night. Many youth think it is fun tokeep awake or sleep late. But I dont think so. Keep your body healthy. I strongly suggest to sleep early.与睡眠有关的英语演讲稿3Staying up late will be detrimental to human health, because the adrenal cortex hormone and growth hormone are all secreted during the night when people are sleeping. The former is secreted before dawn, which can promote the metabolism of carbohydrate in human body, and protect the development of muscle; while the latter is produced only after sleep, which can not only promote the growth and development of young people, but also can delay the aging process of the elderly. As a result, staying up late will cause a variety of harms to human body. First, frequent fatigue and decreased immunityThe most serious sequence caused by staying up late is fatigue and lack of energy. Whats more, the immunity of human body will decrease accordingly. And some other symptoms such as cold, gastrointestinal infections, allergies will also appear.Second, headacheThe next day after staying up late, you will suffer from headache when you are at work or at class. You will be unable to concentrate. Whats more, long-term staying up late and insomnia will also bring invisible damage to our memory.Third, dark circles and puffinessNight is the time for human body to have a good rest. Without adequate rest, you will feel extremely tired, which will lead to poor blood circulation around the eyes, causing dark circles or blood streak in the white of the eye.Fourth, dry skin, dark spots and acneThe period between 11:00 pm to 3:00 am in the next day is the beauty time, and it is also the time for the meridians in human body to move to gall bladder and liver. If these two organs do not have adequate rest, it will be reflected on the skin. So some problems such as roughness, yellowish face, dark spots and acne will appear. Whats worse, long-term staying up late will slowly cause some neurological and psychiatric symptoms such as insomnia, forgetfulness, irritability, anxiety and so on. Fifth, affecting fertilityFor the men and women of childbearing age, if they always stay up late, it will not only affect the motility and quantity of male sperm, but also will affect the secretion of female hormone and the quality of ovum, and it is also likely to influence the menstrual cycle.Sixth, increasing the probability of getting some chronic diseases People who staying up all night always have higher secretion of adrenaline than the average person, which will increase the pressure on metabolism, and thus leading to some chronic diseases, such as hypertension and diabetes.Whats more, there are also other harms caused by staying up late, such as poor eyesight or dysfunction of the liver. We should pay special attention to these bad effects, and try not to stay up late at night.与睡眠有关的英语演讲稿4Today more and more students are inclined to stay up at night.They enjoy the night so much that they dont go to bed until deep into the night or even until the next morning.Hower that would do harm to their health.Students who usually stay up can get tired the next day and they often sleep in class.They cant listen to the teachers heart and soul.As time goes on,they will do bad in their study ,and will be poor health.For these reasons,I would like to advise those students who are staying up not to do that again!You should go to bed before 11 in the evening.Will you take my advice?与睡眠有关的英语演讲稿5Do you always work or study until midnight?Do you often hang out or spend much time in pubs at late night?If you answered yes to either of these questions, you are unfortunately one of the large groups of people who always stay up late. Because of the fierce competition in the society, it seems that everyone has endless work to do and twenty-four hours per day is not enough. Therefore, an increasing number of people stay up late in order to finish the mountainous work. Besides, lots of young people enjoy entertainingat late night. However, many of them are still not aware of the bad effects of staying up late. In fact, it does severe harm to us in three aspects, namely physical health, work efficiency and mental stress.In the first place, staying up late badly impacts on our physical health condition. The human adrenal cortex hormone and growth hormone, which are vital substances for human body, only secrete at night. The former secretes before the dawn facilitating the carbohydrate metabolism and protecting the development of muscle function. The latter only secretes after sleeping. It can improve the growth of the young and slow down the aging of the elderly. However, if people often stay up late, the secretion of these two substances will be gravely impacted. Finally, our health condition will be degraded. It can cause a variety of harms to human body. Normally, frequent staying up late will lead to fatigue and degraded immunity. People may easily get sick when the weather gets a little bit colder or hotter. In addition, it can also cause headache. People may feel heavy in the brain and dizzy for a whole day. Besides, the fertility of both male and female will be impacted. For women, it will affect the secretion of female hormones and the quality of ova. It also tends to affect the menstrual cycle. For men, both the quality and quantity of sperm will be impacted. What is more, staying up late can also damage people’s eyesight, skin and memory capacity, and cause black eyes as well.Furthermore, it negatively impacts on the work efficiency. On the one hand, owing to the discomfort of your health as mentioned above, you may feel distracted from the work. On the other hand, because of the decrease of the memory capacity, your work efficiency will be lower, which means that you may not complete the things as you want. Assume that you are a university student and you plan to review for your psychology examination next week after tomorrow’s class. Nevertheless, you stayed up late yesterday for some reason. Therefore, you probably be late for tomorrow’s class or even skip it. Thus, you must find other time to compensate for it. Afterwards, when preparing your examination, you may feel headache and cannot concentrate on it, thus having difficulty memorizing and understanding the psychological terms and principles. Therefore, your schedule for reviewing chapter 2 and chapter3 will be changed. You can only review chapter 2 and may not finish chapter 3. However, in order to finish reviewing on time, you are more than likely to stay up late again. Then, you will be in the vicious cycle and your work efficiency will be lower and lower.What is also noticeable is that staying up late can bring about mental stress. Since your work efficiency is lower, you probably doubt yourself whether you are a capable person or not. You may think you are not so smart as others and even fear yourself that you can hardly get a good grade in your psychology examination, which makes you feel moreanxious and upset. Besides, if you frequently stay up late, you definitely look tired and in low spirits. Therefore, when working on a group project, maybe nobody wants to be in the same group with you, a low-efficient and anxious person. Thus, you will feel separated from others, which possibly makes you more stressed and upset.In conclusion, although we have a lot of work to do and various activities to participate in, staying up late is by no means a good choice for us. It badly impacts on our physical health, lowers our work efficiency and makes us stressed and anxious. Faced with too much work, we should make good arrangements in advance and maintain a healthy lifestyle.与睡眠有关的英语演讲稿。

为什么保持好睡眠的原因英语作文
为什么保持好睡眠的原因英语作文The Importance of Getting a Good Night's SleepHello everyone! Today, I want to talk to you about something very important – getting a good night's sleep. Do you know why sleep is so important for us? Well, let me tell you all about it!First of all, sleep is crucial for our bodies to grow and develop properly. When we sleep, our bodies have a chance to rest and recharge. Just like how we need to recharge our toys or electronic devices, our bodies need to recharge too! During sleep, our body repairs any damaged cells and tissues, and it also helps our muscles to grow stronger. So, if you want to grow up big and strong, make sure you get enough sleep every night!Do you know that sleep is also important for our brains? When we sleep, our brains have a chance to rest and process all the things we learned during the day. Have you ever had trouble paying attention or remembering things when you didn't get enough sleep? I have! That's because sleep helps our brains to stay sharp and focused. So, if you want to do well in school and remember all those fun facts, make sure you get a good night's sleep!But wait, there's more! Did you know that sleep affects our mood too? Have you ever felt grumpy or easily upset when you didn't sleep well? I know I have! When we don't get enough sleep, we can feel tired and cranky. We might have a hard time getting along with others or enjoying our day. But when we get a good night's sleep, we wake up feeling refreshed and happy. So, if you want to be a happy and friendly person, make sure you get plenty of sleep!Now, let's talk about some tips for getting a good night's sleep. First, it's important to have a regular sleep schedule. Try to go to bed and wake up at the same time every day. This helps our bodies get into a routine and know when it's time to sleep. Second, create a relaxing bedtime routine. You can take a warm bath, read a book, or listen to soft music before going to bed. These activities signal to our bodies that it's time to wind down and get ready for sleep. Finally, make sure your bedroom is a comfortable and quiet place. Turn off any bright lights or loud noises that might disturb your sleep.Remember, getting a good night's sleep is super important for our bodies, brains, and moods. So, let's make sleep a priority and aim for at least 8-10 hours of sleep every night. Sweet dreams, everyone!I hope you find this essay helpful!

睡眠是你的超能力 ted英文观后感
睡眠是你的超能力ted英文观后感全文共6篇示例,供读者参考篇1Sleep Is Really Your Superpower!I just watched this amazing TED Talk called "Sleep is Your Superpower" and it was so cool! The lady who gave the talk, her name is Jill Bolte Taylor, is a brain scientist. That means she studies how our brains work. In the talk, she explained why sleep is just as important for our bodies and brains as eating good food and exercising.Did you know that when you sleep, your brain actually gets cleaned out? It's like a tiny cleaning crew goes through your head and washes away all the trash and gunk that builds up during the day. Isn't that crazy? All the things you think about, learn, and experience during the day leave behind little trails in your brain. If you don't get good sleep, those trails can turn into cobwebs that make it harder for your brain to work properly.But when you do get enough sleep, it's like a deep cleaning for your brain! The cleaning crew washes out those cobwebs andjunk so your brain feels refreshed and ready to take on a new day. That's one of the big superpowers of sleep.Another superpower is that sleep helps reinforce all the things you learned that day and moves them into your long-term memory banks. So if you studied spelling words or learned about fractions, getting enough sleep will篇2Sleep Is Your Superpower - A TED Talk Reaction EssayWow, I just watched this amazing TED Talk called "Sleep is Your Superpower" and it really opened my eyes to how important sleep is! The speaker was a scientist named Matt Walker and he taught me so much about why we need sleep and what happens when we don't get enough.He started by talking about how sleep is kind of like a superpower that helps our brains and bodies recharge. Just like superheroes need to rest after saving the world, we need to sleep to have the energy to do well in school, sports, and life in general. Who knew sleep could be so super?One of the most shocking things I learned is that not getting enough sleep is worse for you than not exercising at all! Dr.Walker said lack of sleep can increase your risk of scary things like heart disease, Alzheimer's, and even car accidents from being tired. That's really scary stuff. I knew sleep was important but I didn't realize just how dangerous not sleeping enough could be.He also talked about the difference between the two main types of sleep - non-REM and REM sleep. Non-REM sleep is when you get that deep restful sleep that helps recharge your body and immune system. REM is that cool dream sleep that helps your brain process emotions and memories. We need a good balance of both for optimum superpower sleeping abilities!One part that really stuck with me is when Dr. Walker talked about what happens in your brain when you're sleep deprived. Apparently, your brain can't get rid of that junk protein stuff that builds up and leads to Alzheimer's as easily. Plus, thesleep-deprived brain also can't create new baby brain cells or neurons that we need for learning and memories. No wonder I always feel like a zombie after a rough night of not sleeping well! My brain is too full of gunk to work properly.Dr. Walker shared some advice at the end for being a super sleeper. First, don't cram for tests or pull all-nighters - it's betterto get a good night's rest. Second, go to bed and wake up at consistent times, even on weekends. Third, keep bedrooms cool, dark, and free of screens before bed. Finally, get outside and get some sunshine during the day since light is one of the most powerful cues for our body clocks.I'm definitely going to start following those tips right away. I can't wait to unlock my true superpowers by getting great sleep! Dr. Walker made me see just how incredibly important sleep is, maybe even more than eating your veggies. Our brains and bodies cannot survive without it.I really want to share what I learned with all my friends and family. Maybe my parents will finally stop nagging me about staying up too late playing video games after hearing how horrible sleep deprivation is for kids' developing brains. We're supposed to get 9-12 hours a night when we're young to power our mighty superhero sleeping abilities!At the same time, I feel bad for all the grown-ups out there who cut themselves short on sleep to work, take care of babies, or just have a busy life. Dr. Walker said most adults need 7-9 quality hours per night, but so many people don't get that. No wonder there are so many grumpy people out there - their sleep powers are drained!Overall, this was one of the most eye篇3Sleep is Your Superpower - A TED Talk ReflectionWow, I just watched the most amazing TED talk by Matt Walker all about the incredible superpower of sleep! You would never guess how important sleep is for our bodies and minds. It's like getting an upgrade to become a smarter, healthier, happier version of yourself every single night.The speaker, Matt Walker, is a sleep scientist and he knows everything there is to know about sleep. He explained that when we sleep, it's like a magic time for our brains to do loads of cool stuff. Our brain has to work really hard all day at school, staying focused, learning, remembering facts, and using ourproblem-solving skills. But when we drift off to sleep, that's when the cleaning crew comes in!You see, while we're snoozing away, our brains actually get flushed out by this genius little system. It washes away all the toxic gunk that builds up while we're awake from thinking and doing work. Isn't that wild? Our brain gets a fresh start every morning once it finishes its nightly scrub down. No more cobwebs or rust to slow us down.But that's just the start of sleep's awesomeness! Matt Walker said that sleep is also super important for locking in our memories from the day before. Everything we learned at school gets packaged up neatly and stored away during sleep. That's why we struggle to remember our times tables if we stayed up too late - those math memories never got filed away properly.The most surprising superpower of sleep is that it literally rewires our brain while we're in dreamland! You know how sometimes you struggle with a really hard math problem, but then the next day the solution just pops into your head? That's because during sleep, your brain was analyzing the problem and creating new pathways and connections to help you figure it out. Sleep does the same for learning new skills too, like that crazy soccer trick you just can't quite master during practice.I was totally blown away when Matt Walker explained that sleep is also crucial for controlling our emotions and moods. Have you ever noticed that when you're overtired, every little thing makes you freak out? Or that you get grumpy or sad for no reason? That's because sleep deprivation makes it really hard to keep our feelings in check. But a good night's sleep is like hitting the reset button - you'll wake up feeling so much calmer and happier.Even our physical health is super linked to sleep! It turns out that not getting enough sleep can mess with how our bodies handle things like fighting off sickness and stabilizing our blood sugar levels. Matt Walker said that without quality sleep, we'd basically be petri dishes of illness walking around. Gross! And forget about being able to run around at recess if you're overtired.Maybe the most shocking part of the whole talk was learning how sleep can determine how long we live. Matt Walker shared that adults who sleep less than 6 hours per night have a 13% higher risk of dying younger than people who sleep enough. BAD sleep can actually lead to an early permanent bedtime! No way I'm messing with those odds.This talk made me see sleep in a completely new light. It's not just a boring break from being awake - it's a magical period where our brains and bodies get these indescribable transformations. We recharge our focus baksteries, download our memories, unlock problem-solving abilities, process our emotions, and get ninja-level health boosts.From now on, I'm cashing in on my full 9-11 hours every single night to grab all those level-ups sleep has to offer. No more complaining about bedtime for this kid! I've got too manysuperpowers to gain from catching my zzz's. Sleep really is the ultimate life hack.Who would have thought that the secret to becoming smarter, healthier, and happier was just laying around in our cozy beds? We're all sitting on incredible strength just by shutting our eyes. Matt Walker showed us that sleep is a heroic act - our brains' only chance to stop villains like fatigue, sickness, and unhappiness. I'll be sleep's biggest supporter from now on because having that power on my side is a dream come true!篇4Sleep is Your Superpower - A TED Talk ReflectionWow, what an amazing TED talk that was! I never knew sleep could be considered a superpower before. Mrs. Thompson showed it to our class last week and I've been thinking about it a lot since then. The speaker was really energetic and made some great points that even us kids could understand.He started off by talking about how we live in a world that is always on – with phones, computers, TV and video games constantly vying for our attention. Because of that, a lot of people, including students my age, aren't getting enough qualitysleep. Can you believe that many kids my age aren't even sleeping 8-9 hours per night? That blew my mind!The speaker explained that when we're tired andsleep-deprived, our brain doesn't work as well. It's harder to concentrate, learn new things, and remember what we've already learned. Plus, we can get moody, irritable, and have lessself-control. I know that's true because there have been times when I stayed up too late and felt like a zombie the next day at school. My mom calls it "Miss Crankypants" when I'm like that from lack of sleep!But then he went into all the incredible things that happen when we get sufficient, high-quality sleep. He said that while we're snoozing at night, it's like a superpower takes over inside our brain and body! Our brain goes into this sort of "housekeeping" mode where it cleans out toxins and sorts through the day's memories and new learnings to lock them into long-term storage. Wild, right?The speaker also talked about how sleep is vital for hormone regulation – things like growth, appetite, and even our mood. So if we want to grow tall and strong, and not be hungry and cranky all the time, we need good sleep. Getting enough z's at nightalso helps boost our immune system to fight off sickness. With all those awesome benefits, sleep really is a legit superpower!One of the most fascinating parts was when he showed colorful brain scan images of kids who weren't getting proper sleep versus those who were. The sleep-deprived kids' brains looked sort of dull and foggy, while the well-rested kids' brains were lit up with bright colors and activity. As a visual learner, that image really drove the point home for me about how crucial sleep is for young, developing brains like ours.The speaker shared tips for establishing good sleep habits too. He said kids our age should aim for 9-12 hours per night, and have a calming bedtime routine to help our bodies and brains wind down properly. That means no screens for at least an hour before bedtime since the blue light messes with our natural sleep cycles. He even recomme nded keeping electronics out of the bedroom completely so we aren't tempted by notifications dinging all night. My parents are definitely going to have to be stricter about enforcing that one for me!Other advice was to go to bed and wake up around the same time each day, even on weekends. Our bodies crave the consistent routine. He also said our sleep environment should becool, dark, and quiet. Maybe I'll ask for a new sound machine or blackout curtains for my birthday this year!At the end, the speaker did a fun thing where he asked us to stretch our arms out in front of us and make a fist with each hand. Then he said "This fist represents your brain's power without enough sleep" and we all looked at our tiny, weak fists. But then he said "And this represents the mighty superpower your brain becomes with sufficient, high-quality sleep every night" and we expanded our arms and hands out wide. Such a simple visual, but it drove the point home so clearly.I left that TED talk feeling inspired to be a "sleep superhero" and make getting quality zzz's a bigger priority. Just like we observe healthy habits for our bodies like eating nutritious foods and exercising, we need to do the same for our sleep health. After all, we're young students whose brains are still developing. We owe it to ourselves to unleash the full sleep superpower potential inside our noggins!Since watching the talk, I've started going to bed a bit earlier and winding down without screens before bed more consistently. I've noticed a difference in how I feel during the day at school already – more focused and energetic. Who knows, maybe my better sleep will help boost my grades too! I've even startededucating my parents and little brother about why sleep is so crucial, especially for kids their ages.Mrs. Thompson said we'd be doing a unit on sleep habits and the science behind sleep in a few weeks. I'm really looking forward to learning more so I can keep being my best "sleep superhero" self. I'll probably re-watch that TED talk too to keep the messages fresh. Maybe when I'm older I'll give my own TED talk someday to inspire other kids (and adults!) to embrace the superpower of sleep. Zzzzzz......篇5Sleep is Your Superpower - A TED Talk ReviewWow, I just watched the coolest TED Talk ever! It was called "Sleep is Your Superpower" by Matt Walker. He's a scientist who studies sleep and he taught me so many amazing things about why sleep is absolutely vital. I never realized just how powerful and incredible sleep really is!The first mind-blowing fact I learned is that sleep is kind of like a superpower for your brain. When you sleep, your brain goes through various sleep stages and cycles. During one really important stage called REM (rapid eye movement) sleep, your brain basically practices and rehashes everything you learnedthat day. It's like hitting the save button on a computer so that all the new facts, skills, and memories you picked up get locked into your brain properly. Without good sleep, Matt Walker says your ability to learn new things is literally cut by half! Can you imagine only absorbing 50% of what you learn each day? That would be terrible.Another unbelievable benefit of sleep is that it's hugely important for keeping your immune system strong and healthy. Matt Walker talked about these cool studies where they had one group of people get great sleep and another group get very poor sleep before giving them all the same virus. The poor sleep group was way more likely to get really sick from the virus! It's like sleep gives your body's defense system a much-needed energy boost to fight off germs and bugs. I'm definitely going to be more careful about getting enough sleep anytime I start feeling under the weather.Sleep also has this remarkable ability to recharge your emotional batteries and keep your mood on an even keel. Matt Walker did studies where people had to look at upsetting images after getting either great sleep or terrible sleep. The bad sleepers had way more negative emotional reactions and couldn't regulate their emotions properly. They got really worked up overthe images while the good sleepers took them in stride. I could totally see this happening in real life too. Think about how cranky and emotional you tend to get when you're overtired from a bad night's sleep. Proper sleep is like filling up your chill pill reserves!One of the most jaw-dropping parts for me was when Matt Walker talked about the link between lack of sleep and obesity/diabetes. Apparently, when you're sleep deprived, your body has a really hard time regulating crucial things like your appetite hormones and your ability to process glucose properly. He showed facts about how kids and adults who got too little sleep were way more likely to become overweight and develop dangerous conditions like diabetes over time. I had no clue that lack of sleep could mess with your body's systems like that, but it makes total sense that your body needs high quality sleep to operate at its best.I also learned that sleep is absolutely vital for athletic performance and muscle recovery. Pro athletes are usually super careful to get optimal sleep so their bodies can repair and heal effectively after tough workouts and competitions. When you're sleep deprived, your reaction times get really slow and you lose strength and coordination. Matt Walker said even getting just an hour or two less sleep than you need can really mess up yourgame. No more staying up late playing video games right before a big soccer match for me!Towards the end, Matt Walker shared a scary statistic that drowsy driving accounts for over 1 million vehicle accidents per year! That's because when you're operating on a sleep deficit, your brain actually starts experiencing micro-sleep periods where it kind of blinks off for a few seconds here and there. You're basically blacking out at the wheel which is obviously super dangerous. Matt Walker made a really good point that we would never dream of drunk driving, but drowsy driving can be just as hazardous.Overall, this TED Talk has made me appreciate sleep in an entirely new way. Before, I just thought of sleep as this boring inactive time when I'm not doing anything fun or productive. But now I realize that high quality sleep is like giving my brain and body a superhero level upgrade in so many vital areas - learning, immunity, emotional health, physical fitness, and much more. I can't believe how many benefits sleep provides!From now on, I'm going to be way more disciplined and make getting around 9-10 hours of sleep per night an absolute top priority, just like Matt Walker recommends for kids my age. No more staying up past midnight and then feeling like a zombiein the morning. Sleep is too crucial to my health and success to shortchange it anymore. My superpower naps and bedtimes await!篇6Sleep Is Your Superpower: A TED Talk ReflectionWow, I just watched the coolest TED Talk all about how sleep is actually a superpower! Can you believe that? I never really thought about sleep that way before. I always just kind of saw it as this boring thing I had to do every night instead of staying up playing video games or watching TV. But this talk made me realize sleep is so much more than that. It's like this secret weapon we all have access to that helps us recharge and be at our best.The speaker started off by talking about how when we're kids, we spend so much of our time sleeping compared to adults. Like over a third of our day is spent conked out in dreamland! He said that's because sleep is critical for growth and development when we're young. It helps our bodies and brains develop properly. Pretty crazy to think that lying there motionless for hours is actually helping us grow up.Then he went into all the amazing things sleep does for our bodies and minds, even as we get older. Like how it helps repair cells, clear out toxins, and process memories from the day so we can learn and remember better. That's why we always feel so groggy and confused if we don't get enough shut-eye. Our brains didn't have time for that mind cleaning routine!My favorite part was when he talked about how sleep gives us a "cognitive boost." That's a fancy way of saying it makes us smarter and able to concentrate more. He said well-rested people can solve problems faster, be more creative, and get better grades. As a kid, I'm all about anything that can help me do better on tests and assignments!The way he explained it is that when we're awake all day, our brain gets tired and overloaded kind of like a computer with too many windows open. Sleep is like hitting the restart button - it clears out the random thoughts and resets the brain so it can start fresh in the morning. That's why we often wake up with great ideas and realizations after "sleeping on it." Our brains worked through stuff overnight when they had peace and quiet.But the coolest superpower sleep gives us is increased physical performance and faster healing. The guy said sleep helps our bodies recover way faster from illnesses and injuries byproducing extra protein molecules. And well-rested athletes can run faster, jump higher, and react quicker. Maybe that's why I'm always so hyper and clumsy when I stay up too late!So in summary, sleep is pretty much the closest thing we have to a real-life superpower! It boosts our minds, bodies, moods, and ability to take on the world every morning when we wake up refreshed. Who would have thought that plain old sleeping could be so amazing and important?The speaker made a really great point that we often treat sleep like an inconvenience, something to push aside in our busy, hyper-scheduled lives. But he said we should start viewing quality sleep as a priority for feeling and performing our best. So instead of considering it a waste of time, look at your 8-10 hours of nightly ZZZs as an investment in recharging your human superpowers!I know I'll definitely be making more of an effort to stick to a regular sleep schedule and get the sleep my body needs from now on. Because quite frankly, who doesn't want to have cool abilities like quicker healing, better moods, ninjalike reflexes and concentration? All you have to do is crawl under the covers and let your brain and body work its regenerative magic while you catch some zzzs. Easy as pie!So to all my fellow kids out there, let this be your wake up call (pun intended) to start taking advantage of the incredible superpower of sleep. Don't fight it or feel guilty about prioritizing it. Lean into those cozy blankets and dream away, because that's where you'll find your secret, superhuman strength. Sleep is officially the new awesome!。
你为什么要睡觉英语作文
As a high school student, Ive often found myself pondering the necessity of sleep, especially during those latenight study sessions when the allure of just one more chapter or one more problem to solve seems to overshadow the need for rest. But sleep, as Ive come to understand, is not just a luxury but a fundamental requirement for our wellbeing, and heres why.First and foremost, sleep is the bodys way of recharging its batteries, much like how a phone needs to be plugged in after a long day of use. During sleep, our bodies undergo a series of restorative processes. For instance, the release of growth hormone helps in the repair and growth of tissues throughout the body, which is particularly important for us teenagers who are still growing and developing.Moreover, sleep is crucial for our cognitive functions. Its during the deep stages of sleep that our brains consolidate the knowledge weve acquired during the day. This is why after a good nights sleep, I often find myself recalling information more easily and thinking more clearly. The brain also works to clear out the waste products that accumulate during our waking hours, which is essential for maintaining brain health.Another aspect of sleep that Ive come to appreciate is its role in emotional regulation. There have been times when Ive gone to bed feeling stressed or upset, only to wake up feeling refreshed and more capable of handling whatever challenges the day brings. It turns out that sleep helps to regulate our emotions by allowing our brains to process and respond to emotional experiences in a healthier way.Sleep deprivation, on the other hand, can have serious consequences. Studies have shown that chronic lack of sleep can lead to a weakened immune system, increasing the risk of illness. It can also lead to weight gain, as it disrupts the balance of hormones that regulate hunger and appetite. Furthermore, sleep deprivation has been linked to a higher risk of mental health issues such as anxiety and depression.In my personal experience, Ive noticed that when I skimp on sleep, my performance in school suffers. Im more prone to making careless mistakes, and my ability to concentrate and remember details is significantly diminished. Its a clear reminder of how important it is to prioritize sleep, even when theres a lot on my plate.But perhaps the most compelling reason to sleep is its impact on our overall quality of life. Sleep is not just about the absence of wakefulness its an active process that contributes to our physical health, mental sharpness, emotional stability, and even our happiness. When we sleep well, were better equipped to face the day with energy and enthusiasm.In conclusion, sleep is an essential component of a healthy lifestyle. Its not something we can afford to neglect, especially as students who are navigating the challenges of adolescence and academic pressures. By making sleep a priority, were investing in our ability to learn, grow, and thrive, both today and in the future. So the next time you find yourself tempted to stay up late, remember that a good nights sleep is a key ingredient in the recipe for a successful and fulfilling life.。
演讲稿:请一定要睡个好觉
演讲:请一定要睡个好觉中英对照翻译Sleep. It's something we spend about a third of our lives doing, but do any of us really understand what it's all about?睡眠占用了我们一生三分之一的时间,但是真的有人知道它到底是怎么回事吗?Two thousand years ago, Galen, one of the most prominent medical researchers of the ancient world, proposed that while we'reawake, our brain's motive force, its juice, would flow out to all the other parts of the body, animating ['ænɪmeɪt] them but leaving the brain all dried up, and he thought that when we sleep, allthis moisture ['mɒɪstʃə] that filled the rest of the body would come rushing back, rehydrating[,riːhaɪ'dreɪt] the brain and refreshing the mind.两千年前,古时候的名医伽林提出,当我们醒着的时候我们大脑的原动力也就是它的液体,会流动到身体所有其他部位,维持它们的活力,但这却使大脑枯竭。
他还认为,在我们睡觉的时候,这些充满了我们身体其他部位的液体会再回到我们的大脑,为大脑补充水分并且使我们更有精神。
Now, that sounds completely ridiculous to us now, but Galen was simply trying to explain something about sleep that we all deal with every day. See, we all know based on our own experience that when you sleep, it clears your mind, and when you don't sleep, it leaves yourmind murky ['mɜːkɪ]. But while we know a great deal more about sleep now than when Galen was around, we still haven't understood why it is that sleep, of all of our activities, has thisincredible restorative [rɪ'stɒrətɪv] function for the mind.虽然这些观点如今我们听来很荒谬,但是伽林很好地解释了那些我们每天都要面对的睡眠的事情。

We've found that sleep may actually be a kind of elegant design solution to some of the brain's most basic needs, a unique way that the brain meets the high demands and the narrow margins that set it apart from all the other organs of the body.所以今天,我想给大家讲一些近期的研究这些研究可能会揭示这些问题。
我们需要一个好的睡眠的英语作文
我们需要一个好的睡眠的英语作文Why We Need a Good Night's SleepSleep is as essential to our well-being as food and water. It is a natural way for our bodies to recharge and reset, allowing us to function at our best during the day. Yet, in today's fast-paced world, more and more people are sacrificing sleep in favor of work, socializing, or other activities. This lack of sleep is taking a toll on our health and productivity. In this essay, we will explore why we need a good night's sleep and its benefits for our physical and mental well-being.First and foremost, sleep is vital for our physical health. During sleep, our bodies repair and regenerate tissues, muscles, and organs. It is also the time when our immune system is the most active, fighting off infections and illnesses. When we don't get enough sleep, our immune system weakens, making us more susceptible to colds, flu, and other diseases. Additionally, sleep plays a crucial role in regulating our hormones, such as those that control appetite and metabolism. Lack of sleep can lead to weight gain, as well as an increased risk of diabetes and heart disease.In addition to physical health, sleep is also essential for our mental well-being. A good night's sleep improves our mood, concentration, and cognitive function. It helps us process information and memories, making it easier to learn and retain new information. On the other hand, sleep deprivation can have serious consequences for our mental health. It can lead to mood swings, irritability, anxiety, and depression. In extreme cases, chronic sleep deprivation has been linked to serious mental health disorders, such as schizophrenia and bipolar disorder.Furthermore, sleep plays a crucial role in our overall performance and productivity. Studies have shown that lack of sleep can impair judgment, decision-making, and reaction time, making it harder to perform tasks efficiently and effectively. This can be particularly dangerous in professions that require high levels of concentration and alertness, such as healthcare, transportation, and law enforcement. In fact, sleep deprivation has been identified as a significant factor in many accidents and disasters, including the Chernobyl nuclear disaster and the Exxon Valdez oil spill.Given the importance of sleep for our health and well-being, it is essential that we prioritize it in our lives. Here are some practical tips for getting a good night's sleep:1. Stick to a consistent sleep schedule: Try to go to bed and wake up at the same time every day, even on weekends.2. Create a relaxing bedtime routine: Engage in calming activities before bed, such as reading, taking a warm bath, or practicing relaxation techniques.3. Make your bedroom a sleep-friendly environment: Keep your bedroom dark, cool, and quiet to promote better sleep.4. Limit exposure to screens before bed: The blue light emitted by electronic devices can disrupt your sleep-wake cycle, so try to avoid screens at least an hour before bedtime.5. Avoid caffeine and heavy meals close to bedtime: Both can interfere with your ability to fall asleep and stay asleep.In conclusion, sleep is a fundamental aspect of our health and well-being. It is crucial for our physical, mental, and emotional health, as well as our performance and productivity. By making sleep a priority in our lives and adopting healthy sleep habits, we can improve our overall quality of life. So, let's put down our smartphones, turn off the Netflix, and give our bodies the rest they need and deserve. Good night, sleep tight, and sweet dreams.。
为什么保持好睡眠的原因英语作文
为什么保持好睡眠的原因英语作文Why We Need to Get Enough Good SleepSleep is really important for kids like me. When I get plenty of sleep, I feel happier, have more energy, and can think more clearly. But when I don't get enough sleep, I feel grumpy, tired, and have a hard time focusing in school. My mom and dad are always reminding me how crucial it is to get good rest each night. Here are some of the main reasons why sleep is so important:Growing Bodies Need SleepOne of the biggest reasons kids need lots of sleep is because our bodies are still growing. Sleep is like fuel that lets our bodies recharge and develop properly. When we're sleeping, our bodies release hormones that help us grow taller and develop muscles, bones, and other tissues. Without enough sleep, we don't get all those good growing hormones, and our growth can get stunted.My friend Tommy is a perfect example. He stays up really late every night playing video games. Now he's one of the shortest kids in our class! His mom said if he had gotten more sleep while he was younger, he might have grown taller. I don't want to end up a shrimp like Tommy, so I make sure to get at least 10 hours of sleep most nights.Better Brain PowerIn addition to helping our bodies grow, sleep is also super important for our brains to develop properly. While we sleep, our brains are hard at work forming new pathways that help us learn and remember things. It's kind of like our brains hit the "save" button on everything we learned that day.I've definitely noticed the difference good sleep makes for my memory and learning. When I'm well-rested, it's so much easier to pay attention in class, remember what I studied, and learn new concepts. But when I stayed up late last week bingeing my favorite cartoon, I had the worst time focusing the next day. My teacher's lessons just weren't sticking in my brain.Sleep also helps us solve problems more creatively. Once I was totally stumped on a tough math problem, but after sleeping on it, I woke up and the solution just popped into my head! Our brains are amazing problem solvers when we give them the energy they need through sleep.Beating Grumpies and MoodinessWe all know how cranky kids can be when they're overtired. I definitely turn into Mr. Grumpypants if I don't get enough sleep. My sister loves to tease me about having "a case of thegrumpies" whenever I'm yawning and snap at her for no good reason.The reason lack of sleep makes us moody is because it messes with our ability to regulate our emotions properly. When our bodies and brains are feeling rested, it's easier to stay calm and in control even when things don't go our way. But if we're running on empty from too many late nights, small stuff can feel like the end of the world and set off mega tantrums.My friend Sara is a perfect example. She stays up way past her bedtime reading under her covers. Then she comes to school the next day completely zombified and cries over every little thing that doesn't go right. Lack of sleep is the ultimate recipe for meltdowns!Staying Healthy and FitDid you know that good sleep can actually help keep us from getting sick as often? It's true! While we're sleeping, our bodies create more antibodies and other cells that help fight off viruses and infections. If we don't get enough quality sleep, our immune systems get weaker and we're more likely to catch whatever cold or flu is going around.Sleep is also really important for kids who play sports or just want to have plenty of energy to run around. When we're sleep deprived, we feel sluggish and tired way faster. I noticed a huge difference in my soccer games if I stayed up late the night before - I'd get winded so much quicker and have a hard time keeping up with everyone.That's because when we sleep well, our bodies release hormones that give us energy and help repair our muscles after physical activity. So getting good rest lets us recover faster and play harder the next day. Just ask any professional athlete - they're super strict about protecting their sleep schedules so they can perform their best.Getting Better SleepNow that we know all the awesome reasons to get sufficient sleep, you're probably wondering how to make sure you're getting quality zzz's each night. Here are some tips:Stick to a regular bedtime. Our bodies do best when we have a predictable schedule. Having a set bedtime every night, even on weekends, helps train our brains to get sleepy at the right times.Create a calming bedtime routine. Things like taking a warm bath, reading quiet stories, or light stretching can help signal to our bodies that it's time to wind down for sleep.Make your room a sleep sanctuary. Having a cool, quiet, dark, and comfy bedroom environment helps our brains and bodies relax fully while we snooze.Avoid tech before bedtime. The blue light from TV, tablet, and phone screens can actually trick our brains into thinking it's daytime and delay our body clocks. Playing video games or watching shows right before bed also revs up our minds when we should be chilling out.If you toss and turn a lot, get out of bed. If you're still feeling wide awake after 20 minutes of trying to sleep, it's better to get up and do something calm and boring (like reading or light stretches) in another room until you start feeling sleepy again. That way you don't spend hours just lying in bed awake.So there you have it - tons of reasons why us kids need to make sleep a priority! Getting enough high-quality shut-eye lets our bodies and brains grow properly, keeps our moods regulated, helps us stay healthy, and lets us perform our mental and physical best. Whenever I'm tempted to stay up too late, I remind myself of all the ways sleep helps me be the best versionof me. Getting zzz's is one of the most important habits a kid can develop!。

为什么睡眠很重要英语作文
为什么睡眠很重要英语作文Sleep is a fundamental aspect of human life, and its importance cannot be overstated. It is a biological necessity that plays a crucial role in our physical, mental, and emotional well-being. In this essay, we will explore why sleep is so vital and the various ways it contributes to our overall health and well-being.Firstly, sleep is essential for the proper functioning of our bodies. During sleep, our bodies undergo a series of physiological processes that are essential for repair and regeneration. This includes the release of growth hormones, which are responsible for tissue repair and muscle growth. Additionally, sleep plays a crucial role in the regulation of our immune system, helping to fight off infections and illnesses. When we don't get enough sleep, our bodies become more susceptible to a range of health problems, including cardiovascular disease, obesity, and diabetes.Another important aspect of sleep is its impact on our cognitive function. During sleep, our brains engage in a process called memory consolidation, where the information we have learned during the day is processed and stored for future use. This is particularly important for tasks that require problem-solving, decision-making, and creativethinking. Studies have shown that individuals who get adequate sleep perform better on cognitive tests and have better memory recall compared to those who are sleep-deprived.Furthermore, sleep is essential for our emotional well-being. During sleep, our brains regulate the production of neurotransmitters, such as serotonin and dopamine, which are responsible for our mood and emotional state. When we don't get enough sleep, these neurotransmitters can become imbalanced, leading to increased feelings of anxiety, depression, and irritability. Additionally, sleep plays a crucial role in the processing of emotional experiences, helping us to better understand and cope with our emotions.Another important aspect of sleep is its impact on our physical appearance. During sleep, our bodies undergo a process called cellular repair, where damaged cells are repaired and new cells are generated. This helps to maintain the health and appearance of our skin, hair, and nails. Additionally, sleep is essential for the regulation of our body's internal clock, known as the circadian rhythm. When this rhythm is disrupted, it can lead to a range of health problems, including weight gain, hormonal imbalances, and skin issues.Finally, it is important to note that the amount of sleep we need can vary from individual to individual. While the recommended amount of sleep for adults is between 7-9 hours per night, some individualsmay require more or less sleep depending on their age, activity level, and individual needs. It is important to listen to our bodies and to establish a consistent sleep routine that allows us to get the rest we need.In conclusion, sleep is a vital component of our overall health and well-being. It plays a crucial role in the repair and regeneration of our bodies, the regulation of our cognitive function, our emotional well-being, and our physical appearance. By prioritizing sleep and establishing a consistent sleep routine, we can improve our overall health and well-being and live happier, more fulfilling lives.。
