Sleep is extremely important for brain health. Minors generally need to have more than 8 hours of sleep, and must ensure high quality. If the sleep time is insufficient or the quality is not high, it will have a bad influence on the brain, and the fatigue of the brain is difficult to recover, which will seriously affect the function of the brain. If teenagers have insufficient sleep or poor sleep quality, they should appropriately increase their sleep time, such as taking a nap in summer, and try their best to improve their sleep conditions. According to the general view, sleep is the main way to eliminate brain fatigue. If you don't get enough sleep for a long time or the quality of sleep is too poor, it will seriously affect the function of the brain, and people who are already very smart will become confused. Many young students suffer from neurasthenia and other diseases, which are often caused by serious lack of sleep. In short, people spend more than one third of their time in sleep. A good sleep of a political party can regulate physiological functions and maintain the balance of the nervous system, which is an important part of life. Poor sleep, lack of sleep, the next day will be wrong, brain swelling, general weakness. Sleep is closely related to healthy work and study. The following aspects can improve the quality of sleep: * moderate sleep 1. One of our important points is that sleep is indispensable. Many books say that adults usually sleep 7-8 hours a day. But recently, American psychology professor James? Dr. Maas pointed out that it is not enough for a person to sleep for 6-7 hours at night. His sleep research shows that only eight hours' sleep can make human body function reach its peak. So what is "moderate amount" is mainly based on "mental and physical recovery". Human sleep can be divided into slow eye movement sleep and rapid eye movement sleep. The concentration of rapid eye movement sleep occurs in the final stage of rapid eye movement sleep, such as memory storage, tissue maintenance, information arrangement and new learning and performance, while rapid eye movement sleep usually occurs after the 8-hour sleep period and lasts for about 90 minutes. Although we may not realize it, most of us don't get enough sleep, which not only reduces the quality of life, but also may cause diseases. In order to make up for this general lack of sleep, Dr. Mas advocated a "nap". This kind of nap means taking a nap for 20 minutes after waking up from a formal sleep every day, which is much better than going to bed early at night. What we particularly emphasize is that although primary and secondary school students say "reducing the burden", they have not relaxed due to various test pressures, and many people obviously lack sleep time. Compared with the past, it is actually open and tense. In fact, it is not worth the loss to the society and the family. We believe that only by sleeping well can we study hard. A good sleep will not hinder your future: sleep time must be guaranteed! * Sleeping environment If you want to sleep well at night, it is very important to pay attention to three appropriate and three bogeys before going to bed. Three appropriate is: take a walk before going to bed. Purple rock collection? Yang Shu said: "When you are asleep, walk a thousand steps in the room, and then you will get a pillow ... cover it and you will be tired. If you are tired, you will think about it, and you will move to the extreme and seek peace." There should be an environment suitable for sleeping, mainly a quiet bedroom and comfortable bedding. Ventilation is an important condition for a bedroom, because fresh air is more important than anything else. No matter what the outdoor temperature is, you should open the window to get some air before going to bed. Choose a comfortable bed, usually a brown elastic bed with moderate hardness or a cork mattress. Pillows should be moderate in hardness and try to be warm in winter and cool in summer. Have a correct sleeping posture. Generally speaking, it is recommended to lie on the right side, with legs slightly bent, and the body naturally relaxed. One hand is bent on the pillow and the other hand is naturally placed on the thigh. Develop good sleep habits. No matter whether you sleep at night or take a nap during the day, try to sleep and get up at the same time, and holidays are no exception. We should take regular and moderate actions. * Follow the biological clock If we get up on time every day and greet the sun regularly every morning, then your biological clock will run on time. Studies have shown that this is one of the key factors to improve sleep quality. One of the factors affecting the operation of biological clock is body temperature. Studies have proved that the fluctuation of human body temperature has a great influence on the rhythm of biological clock. People's body temperature is easy to drop, which is an effective way to adjust the biological clock by using body temperature. If the temperature regulation is out of control, it will cause the disorder of sleep biological clock. There are many ways to control your body temperature, such as taking a bath before going to bed or doing aerobic exercise for 20 minutes before going to bed, so that your body temperature will drop when you sleep. In short, people will fall asleep on time after forming habits. It is most important for teenagers to develop good sleep habits. The biological clock is not easily broken. Don't stay up late on Saturday and Sunday nights, you can't afford to get up during the day, which destroys your biological clock. * Adjusting Diet We often see that a few people have no subjective feeling of poor sleep after eating a lot of coffee, chocolate, cola, tea and other foods or drinks at night, but experiments have confirmed that their deep sleep will be adversely affected. So don't eat these things before going to bed. In order to get a good sleep effect, there should be the following taboos before going to bed: avoid overeating at dinner. Don't eat before going to bed, so as not to increase the burden on the stomach. Avoid strong tea and coffee. Don't drink strong tea, coffee and other foods at night to avoid affecting normal sleep due to mental excitement or frequent urination. Avoid drinking research has proved that drinking seems to help people fall asleep, but it is actually incorrect. In the process of metabolism, wine will release a natural stimulant, which will destroy our sleep in the middle of the night. Noise Many young friends are used to this harsh environment because they are often exposed to some kind of noise. This is not good for our sleep, and it will reduce our sleep concentration.
