Sleep is part of a person's daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you fist drift off into slumber, your eyes will roll about a bit, you temperature will drop slightly, your muscles will relax, and your breathing well slow and become quite regular. Your brain waves slow and become quite regular. Your brain waves slow down a bit too, with the alpha rhythm of rather fast waves 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep. slower your brain waves will be. Then about 40to 69 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep.。
How students can improve sleep quality We know that sleep for brain health is of paramount importance. People generally have required more than eight hours of sleep time, and must ensure high quality. If insufficient sleep time or quality is not high, then the brain will have an adverse effect, the brain's fatigue would be difficult to restore seriously the potential impact of the brain's function. If lack of sleep or poor quality sleep, it should be appropriately increased sleep time, such as a short nap in summer, and to find ways to improve sleep conditions. As a general point of view, sleep is to remove the main form of brain fatigue. If long-term lack of sleep or poor quality sleep, it will seriously affect brain function, it is very clever people will become very confused. A lot of people suffering from diseases such as neurasthenia, because a lot of time is caused by a serious lack of sleep. In short, a person's First, there are many one-third of the time are spent in sleep. While good sleep, can regulate physiological function, the nervous system to maintain balance in life are important. Bad sleep less than the next day will be the first mistake bulging brain, the body can not afford. Sleep and Health at Work and study the relationship between the very closely. The following areas can improve sleep quality: * Sleep to moderate 1, we have an important point of view are: essential to sleep sleep. In a lot of books that adults generally sleep 7-8 hours a day on the same subject. Recently, however, the United States, professor of psychology James? Dr. Ma Si pointed out: one person 6-7 hours of sleep at night is not enough. His sleep study results showed that only 8 hours of sleep so the body can only function of the peak. What is so "modest", mainly "to mental and physical restoration," as the criteria. Human sleep is divided into the slow eye movement sleep and rapid eye movement sleep to two. The concentration of rapid eye movement sleep in memory storage, maintenance organizations, information collation and new learning and performance have occurred in rapid eye movement sleep of the final stage and the rapid eye movement sleep usually occurs in 8-hour sleep period the rear, and can be sustained for about 90 minutes. Although we may not have noticed, but we sleep most of the people are actually not enough, This not only reduces the quality of life, but also may lead to disease. In order to compensate for this widespread lack of sleep, Dr. Ma Si promote "nap." This nap is the official day of sleep to wake up 20 minutes after the nap, the effect of bed early is much better than the evening. In particular, we emphasize that although primary and secondary school students now say "burden", but because of a variety of exam pressure, they are not easy, a lot of people obviously insufficient sleep time. Compared with the past, are in fact dark Mingsong tight. This is in fact both the society or the family are not worth the candle. We believe that only sleep sleep can be a good study. Sleep does not prevent future sleep: sleep time must be guaranteed! * Sleeping environment To get a good night's sleep, attention to appropriate bedtime Three three bogey very important. Three are advised to: Walking bedtime. "Purple rock hidden book? Dependent book," Say: "sleep when the trip around the room a thousand step-by-step, beginning on the pillow cover is God 。

Ventilation is an important condition for the bedroom, because fresh air more important than anything else. Regardless of outdoor temperature high or low, should go to bed before the ventilation window. Choose a comfortable bed, and generally moderate brown stretch of soft and hard or soft wood bed of cotton-padded mattress is better. Pillow soft and hard to moderate, as far as possible冬暖夏凉.

The importance of sleeping Nowadays, the current world is colorful that people have so many things to busy with. Time is always not enough for them. But they will try their best to squeeze time. Giving up the sleeping time is a common way. They always sleep little and give most of the sleeping time to do other thing, which they think is meaningful. In the short term, it seems a good way to get more time. But it will get more harm than benefit in the long term. Not enough sleep will damage people's body health and then some other problem will also come. So I insist that enough sleep is very important.First of all, enough sleep can make people full of energy for a whole day laying a good foundation for everything. It's easy to imagine that the difference between a powerful person and a dismalest person. A good harvest in a day results from a good state. And a good state mostly depends on the good sleep.

Enough rest lead to a well functional body. The most obvious point is that the skin of a sleep well person is better than the one who doesn't sleep well.In a word, although sleep is seems a common and small thing, it is very important. It has great influence on our life. We should make our body get the rest it should have.。
The importance of sleep
With so many obligations and concerns that modern life brings, people don't care much about having a good sleep. Some think that sleep is a waste of time. Others want to sleep better, but cannot. In my opinion,sleep is so important toourhuman being's health!
Good sleep is essential for physical, mental功丁哆股馨噶鹅拴珐茎 and spiritual health. We spend a third of our lives sleeping. It is during sleep time that mental and bodily functions are restored and the body is prepared to face the next day. However, the vast majority of people do not sleep properly, which can cause serious health problems.
Sleeping poorly can cause memory loss, depression, and difficulty concentrating. In adults, the lack of sleep interferes with the ability to assess risks and make decisions. Children are also affected. Sleeping late affect the release of growth hormones, make children more irritable and with less ability to concentrate in school.Also, when we sleep poorly for a long time, our body undergoes physiological changes that may be related to obesity and diabetes.
Make adjustments in your schedule so you can sleep more and better. Remember that the hours of sleep before midnight are essential for a good rest。
How to keep healthy
What is the most important thing in the world? I think it is health.
You can take away our money, house, car, or even our clothes and we can survive. But if our health was taken away, we would surely die. That is why we always try to eat in a healthy way and exercise regularly.
In order to eat healthily, I usually avoid eating food high in fat, like French fries or cookies. I also eat little meat. I eat a lot of vegetables and fresh fruit which are full of vitamins.
Taking exercise every day helps us build a strong body. Regular exercise is an important part of keeping me healthy.
What's more, I think friends are an important part of one's health. Many studies show that people with a wide range of social contacts get sick less than those who don't. I always feel better when I am with friends than when I am alone. When I am with my friends, I always laugh. Laughing is also an important part of health. I like to laugh with my friends.
By eating properly and exercising regularly, I can keep my body at a proper weight and keep healthy. By spending time with my friends, I can keep my mind as well as my body happy. These things sound easy to do, but not many people can manage them. I think a strong will is necessary if we want to keep healthy.
望采纳，谢谢.When it comes to sleep, people's opinions vary.Some people think that we should sleep as much as possible to keep our mind conscious.Some people think that we shouldn't sleep too much because long time sleep makes people sleepy.In my opinion, appropriate sleep can not only refresh our mind but also keep us energetic.当谈到睡眠的时候，人们意见不一。
就我看来，我认为适当的睡眠不仅能让我们的大脑更清醒，而且也能让我们更有活力。First of all, enough sleep makes us energetic.After a day's working, people feel tired.Therefore, a good and enough sleep can help people recover from the exhausting status.第一，充足的睡眠让我们更有活力。
Secondly, sleep enough can avoid illness.It is investigated that more than 90% people who suffers from insomnia are tending to fall ill easily compared with those who have enough sleep.第二，充足的睡眠能让我们避免得病。据调查，90%的失眠患者比那些有着充足睡眠的人更容易生病。
Thirdly, enough sleep benefits our mind.According to researcher from American and French, the “Sharp Wave Ripple” in brain which is responsible for strengthen memory can only appear when people fall into deep sleep.If we have enough sleep, then our memory will be improved so that we can learn things more efficiently.第三，充足的睡眠让我们的大脑更有益。美国和法国的研究者支出，大脑中的“尖波涟漪”专门负责记忆，这种涟漪只会在深度睡眠的状态下出现。
如果睡眠充足，那么记忆会得到改善，因此我们能够更有效的学习。All in all, enough sleep makes us energetic, benefit our mind and also help us to avoid from being ill.Hence, people should get enough sleep.总之，充足的睡眠能让我们更有活力，有益于我们的大脑，能够避免生病。
It's clear that everyone needs to sleep. Most people rarely think about how and why they sleep, however. We know that if we sleep well, we feel rested. If we don't sleep enough, we often feel tired and irritable.
It seems there are two purposes of sleep: physical rest and emotional and psychological rest. We need to rest our bodies and minds. Both are important in order for us to be healthy. Each night we alternate between two kinds of sleep: active sleep and passive sleep. The passive sleep gives our body the rest that's needed and prepares us for active sleep, in which dreaming occurs.
Throughout the night, people alternate between passive and active sleep. The brain rests, then it becomes active, then dreaming occurs. The cycle is repeated: the brain rests, then it becomes active, then dreaming occurs. This cycle is repeated several times throughout the night. During eight hours of sleep, people dream for a total of one and half hours on the average.
