Hibernation is more than sleep. It is a very deep sleep.The animals temperature drops to just over zero centigrade,and its heart beats very slowly. People who find hibernating animals asleep often think that they are dead: the body feels very cold, and the creature may breathe only once every five minutes. A hibernating animal cannot feel any pain. You can touch it, or even pull its tail, without causing it to move or wake up. In its hibernating state it can even live in a poisonous atmosphere for a long time without any ill effect.
Hibernating in this way, the animal can sleep all through the winter. You might wonder how it manages to live without eating for so many months. The answer lies in two facts. Thefirst is that it has stored supplies of fat in its body during the summer and autumn. The second is connected with the main use the body makes of food -- to supply the energy for movement. We have seen that hibernating animal reduces movement to far below the ordinary level. Even the movements of the heart and lungs are greatly reduced. The animal hardly makes any movement, hardly use any energy, and hardly needs any food.
Some animals, including some bears only half hibernate.That is to say, they sleep during the winter, but their sleep is not deep and their body temperature does not drop, as they are warm-blooded animals. In the antumn the bear eats and eats and becomes very fat. His hair grows longer. Soon he has a thick covering of fat and fur. In November he finds a place to lie down and goes to sleep. On warm winter days he may think spring has arrived; he gets up and walks around. When he sees that the snow is still thick on the ground, he quickly goes to sleep again.

Every person needs sleep everyday. But with the high development of society, most people have more and more things to do and have less time to sleep. As a result, many people are lack of sleep. For a short time, they may not realize the bad side of it, but it will bring something bad for them after a long term. First of all, lack of sleep will do harm to people’s look. If they do not sleep enough, they will get black eyes and bad skin easily, which will make people look no so beautiful. Secondly, lack of sleep is bad for the spiritual outlook. A person who lacking of sleep always looks tired and has no power to do things. Last, not enough sleep for a long time will have bad influence of thought. They always can’t be active in mind.
I often go to bed at 21:30, because my parents force me to sleep. They tell me that a good rest can bring me a good body. Before go to sleep, I usually drink a cup of milk. I always have a good sleep at night. I often get up at 6:30. Its very early, but I dont feel tired. I can eat the breakfast at home and do not need to hurry. I am often spirit in the class, but some of my classmates sometime would sleep in the class. Maybe they are short of sleep.
According to a survey, we know most middle school students sleep less than 7 hours each night, much less than required.
First of all, the students have too much homework. Second, schools and parents pay less attention to their sleep. Another important reason is that many students play with their cell phones or iPads before sleeping. This is one of the main reasons for bad sleep. Other reasons include stress and bad moods.
So we must take some ways to stop this. First, less homework should be given to the students by teachers and parents. Second, students need to keep away from digital devices for at least an hour before sleep .Last, more attention should be paid to their health.
Enough sleep is very important. It affects we are happy or not. We can easily find if we sleep enough in the night, we usually have a good mood next day. But, if we do not have enough sleep, sometimes we will feel depressed without a reason. What’s more, sleep also affects our study or work. Try to imagine that a sleepy person how can he listen to the teacher in class or work in their position. It must be a hard job or in low efficiency. Thus, if a person sleep enough, he can do better in their life. In addition, do you find that a person with good sleep usual do not have acne, because enough sleep balance their internal secretion and detox. Knowing the importance of enough sleep, do you still stingy about sleep? Do you still dare to sleep late?
With 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.
Many 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 to keep awake or sleep late. But I dont think so. Keep your body healthy. I strongly suggest to sleep early.
Staying 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 immunity
The 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, headache
The 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 puffiness
Night 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 acne
The 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 fertility
For 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.
Today 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?
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 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 entertaining at 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 more anxious 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.
