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

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

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。

下面是我整理的与睡眠有关的英语演讲稿，欢迎大家阅读分享借鉴。

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。

让我们谈谈睡眠英语作文

让我们谈谈睡眠英语作文Sleep is a fundamental physiological process that is essential for human health and well-being. It is a period of rest and restoration for the body and mind, allowing us to recharge and prepare for the challenges of the day ahead. In this essay, we will explore the importance of sleep, the factors that influence sleep quality, and the consequences of sleep deprivation.Firstly, sleep plays a crucial role in maintaining physical and mental health. During sleep, the body undergoes a series of restorative processes that support the immune system, regulate hormone levels, and promote tissue repair. This is particularly important for individuals who are physically active or recovering from illness or injury. Additionally, sleep is essential for cognitive function, as it allows the brain to consolidate memories, process information, and engage in problem-solving activities.Moreover, the quality of sleep can have a significant impact on our daily lives. Factors such as stress, diet, and environmental conditions can all influence the duration and quality of our sleep. Stress, forinstance, can trigger the release of hormones that disrupt the body's natural sleep-wake cycle, leading to insomnia or restless sleep. Similarly, the consumption of caffeine, alcohol, or heavy meals close to bedtime can interfere with the body's ability to fall and stay asleep.The environment in which we sleep can also play a crucial role in sleep quality. A quiet, dark, and cool bedroom can promote better sleep, as it helps to regulate the body's internal clock and minimize external stimuli that can disrupt sleep. Conversely, exposure to blue light from electronic devices, such as smartphones and computers, can suppress the production of melatonin, a hormone that regulates the sleep-wake cycle.In addition to the physical and cognitive benefits of sleep, it is also important to consider the emotional and psychological aspects of sleep. Adequate sleep is closely linked to mood regulation, as it helps to reduce feelings of anxiety, depression, and irritability. Conversely, sleep deprivation can exacerbate these negative emotions and lead to decreased productivity, poor decision-making, and strained relationships.The consequences of sleep deprivation can be far-reaching and can have a significant impact on an individual's overall health and well-being. Chronic sleep deprivation has been linked to a range of health problems, including cardiovascular disease, type 2 diabetes, andobesity. Additionally, sleep-deprived individuals are more prone to accidents and injuries, as their cognitive and physical abilities may be impaired.To address the issue of sleep deprivation, it is important to adopt healthy sleep habits and practices. This may include establishing a consistent sleep schedule, creating a relaxing bedtime routine, and limiting exposure to blue light before bed. Additionally, engaging in regular physical activity and maintaining a balanced diet can also contribute to better sleep quality.In conclusion, sleep is a crucial component of overall health and well-being. By understanding the importance of sleep, the factors that influence sleep quality, and the consequences of sleep deprivation, individuals can take proactive steps to improve their sleep and enhance their physical, mental, and emotional well-being. Ultimately, prioritizing sleep should be a key part of a healthy lifestyle.。

睡眠英文演讲稿

睡眠英文演讲稿Sleep is an essential part of our daily routine, and it plays a crucial role in maintaining our physical and mental health. In today's fast-paced world, many people underestimate the importance of quality sleep and often sacrifice it for work, socializing, or other activities. However, the consequences of sleep deprivation can be severe, affecting our overall well-being and productivity.First and foremost, sleep is vital for our physical health. During sleep, our bodies undergo essential processes such as tissue repair, muscle growth, and the release of hormones that regulate growth and appetite. Without an adequate amount of sleep, these processes are disrupted, leading to a weakened immune system, increased risk of chronic illnesses such as heart disease and diabetes, and slower recovery from illness or injury. Additionally, lack of sleep can contribute to weight gain and obesity, as it disrupts the balance of hormones that control appetite and metabolism.Furthermore, sleep is crucial for our cognitive function and mental well-being. Adequate sleep is essential for learning, memory consolidation, and problem-solving skills. It also plays a significant role in regulating mood and emotional stability. On the other hand, sleep deprivation can impair attention, alertness, concentration, reasoning, and problem-solving, making it difficult to perform daily tasks effectively. It can also lead to mood swings, irritability, anxiety, and depression.In today's society, many people struggle to get enough sleep due to various factors such as work demands, social obligations, electronic devices, and lifestyle choices. However, it is essential to prioritize sleep and make it a non-negotiable part of our daily routine. Here are some tips for improving sleep quality:1. Establish a regular sleep schedule: Try to go to bed and wake up at the same time every day, even on weekends. This helps regulate your body's internal clock and improve the quality of your sleep.2. Create a relaxing bedtime routine: Engage in calming activities such as reading, taking a warm bath, or practicing relaxation techniques before bed to signal to your body that it's time to wind down.3. Make your sleep environment comfortable: Keep your bedroom dark, quiet, and cool, and invest in a comfortable mattress and pillows to create an optimal sleep environment.4. Limit exposure to screens before bed: The blue light emitted by electronic devices can interfere with your body's natural sleep-wake cycle, so it's essential to avoid screens at least an hour before bedtime.5. Avoid stimulants and heavy meals close to bedtime: Caffeine, nicotine, and large meals can disrupt sleep, so it's best to avoid them in the hours leading up to bedtime.In conclusion, sleep is a fundamental pillar of our overall health and well-being. It is essential for physical health, cognitive function, and emotional stability. Prioritizing sleep and adopting healthy sleep habits is crucial for maintaining a balanced and fulfilling life. By making sleep a priority, we can improve our quality of life and enhance our productivity and overall happiness. Thank you.。

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.

关于好好睡觉的演讲稿英文

关于好好睡觉的演讲稿英文Good evening, ladies and gentlemen. Today, I am here to talk to you about the importance of getting a good night's sleep. As we all know, sleep is essential for our overall health and well-being. However, in today's fast-paced and busy world, many of us do not prioritize sleep as much as we should. We often sacrifice sleep in order to meet work deadlines, socialize, or simply because we cannot seem to fall asleep.Lack of sleep can have serious consequences on our physical and mental health. It can lead to a weakened immune system, increased risk of chronic diseases such as diabetes and heart disease, and even weight gain. Moreover, sleep deprivation can impair our cognitive function, memory, and decision-making abilities, which can negatively impact our performance at work or in school.In order to ensure that we get a good night's sleep, it is important to establish a regular sleep schedule. This means going to bed and waking up at the same time every day, even on weekends. By doing so, we can regulate our body's internal clock and improve the quality of our sleep.Creating a relaxing bedtime routine can also help us fall asleep more easily. This can include activities such as reading a book, taking a warm bath, or practicing relaxation techniques such as deep breathing or meditation. It is important to avoid stimulating activities, such as watching TV or using electronic devices, before bedtime as they can interfere with our ability to fall asleep.Additionally, paying attention to our sleep environment is crucial. A comfortable mattress, supportive pillows, and a cool, dark, and quiet room can all contribute to a better night's sleep. It is also important to avoid consuming caffeine, alcohol, or heavy meals close to bedtime, as they can disrupt our sleep patterns.Furthermore, engaging in regular physical activity can help us fall asleep faster and enjoy deeper sleep. However, it is important to avoid vigorous exercise close to bedtime,as it can have the opposite effect. Finding a balance between being physically active during the day and winding down in the evening is key to improving our sleep quality.In conclusion, getting a good night's sleep is essential for our overall health and well-being. By prioritizing sleep, establishing a regular sleep schedule, creating a relaxing bedtime routine, paying attention to our sleep environment, and engaging in regular physical activity, we can improve the quality of our sleep and reap the many benefits that come with it. So, let's all make an effort to prioritize sleep and make it a priority in our lives. Thank you.。

TED演讲【一定要睡个好觉——有一个重要的原因!】20160414

00:11Sleep. 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正有人知道它到底是怎么回事吗？00:19Two thousand years ago, Galen, one of the most prominent medical researchers of the ancient world,proposed that while we're awake, our brain's motive force, its juice, would flow out to all the other parts of the body, animating them but leaving the brain all dried up, and he thought that 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 Galen was simply trying to explainsomething about sleep that we all deal with every day. See, we all know based on our own experiencethat 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 is that sleep, of all of our activities, has this incredible restorative function for 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，它的液体会流动到身体所有其他部位维持它们的活力，但这却使大脑枯竭并且他认为，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虽然这些观点如今我们听来很荒谬但是伽林很好的解释了那些我们每天都要面对的睡眠的事情那么，根据自身的经验我们都知道如果我们睡觉了，我们的头脑会变的清醒而如果我们没有睡觉大脑就会变糊涂我们现在对睡眠的了解比伽林那个时期多了很多但是我们仍然不知道为什么在我们所有的活动中，只有睡眠有如此这般可以促使我们头脑变得清晰的功能01:17So today I want to tell you about some recent research that may shed new light on this question. 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。

英语文章听力：为什么我们要睡觉

Why Do We Sleep?Dear A Moment of Science,Why do we sleep? I know this question has been debated by scientists and philosophers for centuries, but are there any hard and fast answers?Good question! First, it’s true that scientists have long pondered the mystery of sleep why we do it and why it’s necessary. We know that going without sleep for too long can seriously damage health, so there’s good reason to believe that getting enough sleep is important for our well-being.But exactly how and why that’s the case is still an open question. Some research, though, may shed a little light on the problem. For instance, scientists at the University of Rochester Medical Center in New York did a study with mice, and found that during sleep their brains flush out toxins that accumulate during the day.More specifically, the study found that sleep sort of changes the brain’s cellular structure. When the mice were asleep or anesthetized, the researchers found that there was more space between their brain cells, allowing a sort of brain plumbing apparatus called the glymphatic system to open wide and allow fluid to flow quickly through the brain.Other studies have shown that toxic molecules build up in the space between brain cells. Researchers at the University of Rochester found that those molecules vanished faster from the brain when the mice were asleep.So what does this mean? Well, it could give scientists new ways to study and potentially treat brain disorders like Alzheimer’s by targeting the glymphatic system and helping it better flush away brain toxins.。

TED英语演讲稿：我们为什么要睡觉_演讲稿简介：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 frightedthee?” 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 sleep changes 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 ofour 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 are actually 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, a whole 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 processingand 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 will vary, 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 thesix-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 thefreeway 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 neuralproccessing 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 things associated with sleep loss that are morethan 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 the biological 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, when people 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 physicallylinked 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 sleep disruption 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 havethe 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 apre-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 tendency to 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)。

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 Maintaining Good SleepIntroductionSleep is a vital aspect of human life, as it plays a crucial role in maintaining physical health, mental well-being, and overall quality of life. Many people, however, underestimate the importance of getting adequate and good-quality sleep. In this article, we will explore the reasons why maintaining good sleep is essential for our health and well-being.Physical HealthOne of the primary reasons why it is important to maintain good sleep is its impact on physical health. During sleep, the body repairs and rejuvenates itself, strengthening the immune system and promoting overall wellness. Chronic sleep deprivation has been linked to an increased risk of various health problems, including obesity, heart disease, diabetes, and stroke. By getting enough restful sleep, we can help reduce the risk of these serious health conditions and improve our overall physical health.Mental Well-beingIn addition to its impact on physical health, sleep also plays a crucial role in mental well-being. Adequate sleep is essential for cognitive function, memory consolidation, and emotional regulation. Lack of sleep can lead to cognitive impairment, mood swings, and increased stress levels. By prioritizing good sleep, we can enhance our mental clarity, concentration, and emotional resilience, leading to better overall mental health.Quality of LifeMaintaining good sleep is essential for improving our overall quality of life. When we are well-rested, we are more likely to have higher energy levels, improved mood, and better overall productivity. Good sleep also allows us to better cope with daily stressors and challenges, leading to a more positive and fulfilling life experience. By prioritizing sleep, we can enhance our overall quality of life and ensure that we are better equipped to handle life's demands.Tips for Better SleepTo maintain good sleep, it is important to establish healthy sleep habits and prioritize restful sleep. Some tips for improving sleep quality include:1. Establish a consistent sleep schedule and stick to it, even on weekends.2. Create a relaxing bedtime routine to signal to your body that it is time to sleep.3. Ensure your sleep environment is conducive to rest, with a comfortable mattress, pillows, and bedding.4. Limit exposure to screens and artificial light before bedtime, as they can disrupt the natural sleep-wake cycle.5. Avoid caffeine, alcohol, and heavy meals close to bedtime, as they can interfere with sleep quality.ConclusionIn conclusion, maintaining good sleep is essential for our physical health, mental well-being, and overall quality of life. By prioritizing restful sleep and establishing healthy sleep habits, we can improve our overall health and well-being. It is important to recognize the importance of sleep and make it a priority in our daily lives. Let us all strive to get the sleep we need to live our best and healthiest lives.。

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Title: The Importance of Getting Good SleepDo you ever feel grumpy, tired, or have trouble focusing in class? Well, that could be because you're not getting enough good sleep! Sleep is super important for our bodies and minds, and it's crucial that we get enough of it every night.Let me tell you why getting good sleep is so important, and why you should make it a priority!Sleep helps our brains work better.When we sleep, our brains get a chance to rest and recharge. During sleep, our brains organize and store all the information we learned during the day. Without enough sleep, our brains can't do this properly, and we end up feeling confused and forgetful.Imagine your brain is like a computer. If you never turned off your computer and let it rest, it would eventually get overloaded and start working really slowly or even crash! Our brains need that downtime to function at their best.Sleep boosts our memory.Have you ever studied really hard for a test, but then couldn't remember anything the next day? That's probably because you didn't get enough sleep!During sleep, our brains process and consolidate memories from the day before. So, if you don't get enough sleep, those memories don't get stored properly, and you end up forgetting a lot of what you learned.It's like trying to put books on a shelf, but the shelf is already too full – some of those books (or memories) are going to fall off and get lost!Sleep helps us grow and stay healthy.When we sleep, our bodies release special hormones that help us grow and stay healthy. One of these hormones is called growth hormone, which (as the name suggests) helps our bodies grow taller and stronger.Sleep also helps our bodies repair themselves from any injuries or illnesses. When we're sick, our bodies need extra sleep to fight off the germs and heal properly.Without enough sleep, our bodies can't do these important jobs, and we end up feeling tired, weak, and maybe even get sick more often.Sleep gives us energy.Have you ever felt really tired and grumpy after a night of not getting enough sleep? That's because sleep is how our bodies recharge their batteries!When we sleep, our bodies get a chance to rest and restore our energy levels. If we don't get enough sleep, we end up feeling exhausted and drained, which makes it hard to focus and have fun during the day.It's like trying to play a video game with a controller that has no batteries – it just won't work very well!Sleep helps us stay happy and focused.Besides feeling tired and grumpy, not getting enough sleep can also affect our moods and ability to concentrate.When we're well-rested, it's easier to pay attention in class, follow directions, and stay calm and happy. But when we're sleep-deprived, we're more likely to feel frustrated, angry, or sad for no real reason.Sleep helps us regulate our emotions and stay focused, so we can get our work done and have fun with our friends and family.So, as you can see, getting enough good sleep is super important for our bodies and minds! It helps us learn, grow, stay healthy, and feel happy and energized.Here are some tips to help you get the best sleep possible:Stick to a regular sleep schedule, even on weekends. Our bodies love routine!Create a relaxing bedtime routine, like taking a warm bath or reading a book.Make sure your bedroom is cool, dark, and quiet – the perfect sleep environment!Avoid screens (like TVs, phones, and tablets) for at least an hour before bedtime.Get plenty of exercise and fresh air during the day.If you follow these tips and make sleep a priority, you'll wake up feeling refreshed, energized, and ready to take on the day!So, the next time you're feeling tired or having trouble focusing, remember how important sleep is for your growing body and mind. Sweet dreams!。
