Why do people sleep? As the title suggests, thank you

Of course not, if you don't sleep for three days, everyone will collapse, if you don't sleep for five days, your body's functions will be reduced by 60%-70%, and if you don't sleep for seven to ten days, you will die! The reason for sleeping is to let yourself relax the whole body to relieve the fatigue and stress of the day Second, the cells of the whole body of the human body need to be repaired only when you are sleeping, and when you are not sleeping, you need to provide all kinds of nutrients needed for human activities!

Organ detoxification worksheet when the human body sleeps at night! 1. 9-11 p.m. is the time for immune system (lymphatic) detoxification, and this time should be quiet or listening**. 2. From 11 p.m. to 1 a.m., liver detoxification needs to be carried out in deep sleep.

3. At 1-3 o'clock in the morning, the same is true for the detoxification of gallbladder. 4. 3-5 a.m., detoxification of the lungs. This is why people who cough cough the most violently during this time, because the detoxification action has reached the lungs; Cough suppressants should not be used to inhibit the elimination of waste deposits.

5. At 5-7 o'clock in the morning, for the detoxification of the large intestine, you should go to the toilet to defecate. 6. From 7 to 9 a.m., when the small intestine absorbs a large amount of nutrients, breakfast should be eaten. It is best for the healer to eat early, before 6:30 o'clock, before 7:30 for health practitioners, and those who do not eat breakfast should change their habits, even if they delay until the point of eating, it is better than not eating.

7. Midnight to 4 a.m. is the period of spinal hematopoiesis, which must be asleep and should not stay up late.

Sleep is very important for humans and other mammals, and normally people should be asleep at 1-1 4 times. This sleep time does not mean that you have to sleep for so long at once, but sleep is very important to the human body, and what are the important ones, including the following:

Clause. 1. There are many proteins in the human body that need to be synthesized, which mainly occur during sleep, especially growth hormone is mainly secreted at night and in the sleep state, which is very important for human growth and development, especially the growth of height;

Clause. 2. Sexual development, sex hormones and pineal hormone are mainly developed at night, and adequate sleep is conducive to improving or promoting sexual development and maturation;

Clause. Third, the brain function is restored, people need to remember a lot of things during the day, the memory during the day is only a superficial input process, and the real formation of a solid memory needs to be integrated by the brain at night, protein synthesis and memory improvement, so if people who do not sleep well will have symptoms such as memory loss;

Clause. Fourth, sleep can make the muscles of the whole body bury and relax the lead feast, the metabolites of the whole body are cleared, so that people's mental state can be significantly improved, so sleep is a very, very important thing for people, and food, is a behavior that human life can not lack.

The most convincing argument is that of Professor Hartman, director of the sleep laboratory at the Boston Psychiatric Center. He believes that sleep has two functions: the first is to eliminate physical fatigue, and the second is to eliminate mental fatigue.

In his opinion, the elimination of physical fatigue is unquestionable, and the function of eliminating mental fatigue has been discovered in recent years in his research on short sleepers. An extra hour of sleep will not only give you more energy at work, but you may also save your own life. "Many people know that they feel dizzy when they lack sleep, and in fact, symptoms such as sleep clock disorders, breathlessness and weakness in the limbs are all caused by lack of sleep.

Modern medicine has also confirmed that healthy lifestyle habits and regular sleep can make the body's hormones secrete normally and maintain a relative balance, so as to ensure that the vital organs work in a stable internal environment Sleep experts believe that sleep is an important physiological process in metabolic activities. Without sleep, there is no health, and lack of sleep will not only not be replenished by the body's consumption, but also cause imbalance in the internal environment due to insufficient hormone synthesis.

After doing a series of studies on sleep and human immunity, immunologists in the United States believe that sleep can not only eliminate fatigue, but also have a close relationship with improving immunity and the ability to resist diseases. People who get enough sleep have a significant increase in T lymphocytes and B lymphocytes in their blood, which are the main force of immunity in the body. Drowsiness is a sign of considerable brain fatigue and should not wait until this time to go to sleep.

Only by developing the habit of sleeping regularly and ensuring that the sleep time is not less than 7 hours a day can the normal operation of the sleep center biological clock be maintained. Therefore, young people should also learn to control their living habits and not let the natural rhythm be disrupted and fall into a vicious circle. Follow the laws of nature, "the sun rises and the sun sets".

Envy Zenye.

About one-third of a person's life is spent in sleep, which shows how important sleep is to everyone. In a sense, the quality of sleep determines the quality of life. Sleep can be divided into two completely different states:

One is called fast-wave sleep, and some people call this sleep state REM sleep. As the name suggests, the eyes move very quickly during sleep, and the brain is also very active, and people dream during this period. The other state is called slow-wave sleep, which is the deepening of the first state, and the sleeper enters a deeper state of unconsciousness.

Scientists have found that fast-wave sleep and slow-wave sleep work differently, and the two states also alternate during sleep. Sleep rests the brain and cerebellum. Animals need to sleep, whereas plants without brains don't; Some organs in the human body, such as the liver, do not rest.

This suggests that sleep is a phenomenon specific to the whole brain, and that at least slow-wave sleep can allow the brain to repair the damage caused by free radicals. Free radicals are by-products of metabolism and can damage the body's cells. Other organs can repair this damage by giving up and replacing damaged cells, but the brain cannot do so, and can only put people into a state of sleep, especially slow-wave sleep, so that human tissues can use this rare "leisure time" to carry out "emergency repair" operations.

It's a simple and complex question! How can this question be asked? Why you sleep is the same as why you eat and why you drink water!

It is an inexplicable habit that has been passed down from our ancestors! Hehe. The four major elements of human health: 1 Adequate sleep, 2 Good mood, 3. Balanced nutrition, 4. Moderate exercise, so people want to live healthily!

About one-third of a person's life is spent in sleep, which seems to be a fundamental element of biology, but scientists still don't know why they sleep. According to the British magazine New Scientist, scientists have come up with several theories about the cause of sleep, ranging from simple theories to complex theories involving memory processing, but none of them have been confirmed. Sleep is made up of two completely different states:

One is fast-wave sleep, when the eyes are constantly turning and the brain is very active, and most dreams appear during this period; The other is slow-wave sleep, which is a deeper state of unconsciousness. The roles of the two states are obviously different, but they are inexplicably intertwined. In natural sleep, slow-wave sleep is always followed by a period of fast-wave sleep, so it's likely that their functions are interrelated in some way.

Sleep is at the service of the brain. One of the reasons is that animals sleep and plants do not sleep, and other organs of the human body, such as muscles and liver, do not rest. This year, scientists have confirmed that the cerebellum sleeps.

This suggests that sleep is a brain-wide phenomenon, and researchers are beginning to agree that at least slow-wave sleep is the time when the brain repairs free radicals and causes damage. Free radicals are by-products of metabolism and can damage the body's cells. Other organs can mend this damage by giving up and replacing damaged cells, but the brain can't do that.

Therefore, slow-wave sleep is like a team that repairs a highway at night, working in the dead of night. So what is fast-wave sleep? Some researchers have suggested that this is a tinkering made by the brain when examining slow-wave sleep.

Other researchers believe that it is related to early brain development, but they do not know for sure. It seems that this issue will have to be left to be resolved later.
