Do 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 oneof the large groups of people who always stay up late. Because of the fiercecompetition in the society, it seems that everyone has endless work to do andtwenty-four hours per day is not enough. Therefore, an increasing number ofpeople stay up late in order to finish the mountainous work. Besides, lots ofyoung people enjoy entertaining at late night. However, many of them are stillnot aware of the bad effects of staying up late. In fact, it does severe harm tous in three aspects, namely physical health, work efficiency and mentalstress.
In the first place, staying up late badly impacts on our physical healthcondition. The human adrenal cortex hormone and growth hormone, which are vitalsubstances for human body, only secrete at night. The former secretes before thedawn facilitating the carbohydrate metabolism and protecting the development ofmuscle function. The latter only secretes after sleeping. It can improve thegrowth of the young and slow down the aging of the elderly. However, if peopleoften stay up late, the secretion of these two substances will be gravelyimpacted. Finally, our health condition will be degraded. It can cause a varietyof harms to human body. Normally, frequent staying up late will lead to fatigueand degraded immunity. People may easily get sick when the weather gets a littlebit colder or hotter. In addition, it can also cause headache. People may feelheavy in the brain
and dizzy for a whole day. Besides, the fertility of bothmale and female will be impacted. For women, it will affect the secretion offemale hormones and the quality of ova. It also tends to affect the menstrualcycle. For men, both the quality and quantity of sperm will be impacted. What ismore, staying up late can also damage people’s eyesight, skin and memorycapacity, 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 feeldistracted from the work. On the other hand, because of the decrease of thememory capacity, your work efficiency will be lower, which means that you maynot complete the things as you want. Assume that you are a university studentand you plan to review for your psychology examination next week aftertomorrow’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, youmust find other time to compensate for it. Afterwards, when preparing yourexamination, you may feel headache and cannot concentrate on it, thus havingdifficulty 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 tofinish 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 andlower.
What is also noticeable is that staying up late can bring about mentalstress. Since your work efficiency is lower, you probably doubt yourself whetheryou are a capable person or not. You may think you are not so smart as othersand even fear yourself that
you can hardly get a good grade in your psychologyexamination, which makes you feel more anxious and upset. Besides, if youfrequently 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 samegroup with you, a low-efficient and anxious person. Thus, you will feelseparated from others, which possibly makes you more stressed and upset.
In conclusion, although we have a lot of work to do and various activitiesto participate in, staying up late is by no means a good choice for us. It badlyimpacts on our physical health, lowers our work efficiency and makes us stressedand anxious. Faced with too much work, we should make good arrangements inadvance and maintain a healthy lifestyle.。
