What are the brain hygiene? urgent

In order to enhance brain function and improve its efficiency, we must pay attention to "brain hygiene", that is, using the brain should conform to the physiological characteristics of the brain, that is, to do the following:

1) Ensure adequate sleep.

Sleep is a process in which brain cells get a thorough rest. Deep and quiet sleep is very important for restoring energy and physical strength and eliminating fatigue. Appropriate sleep time depends on different ages, constitutions, habits and seasonal changes. Teenagers need to sleep for 8-9 hours. If you don't get enough sleep, you can't fully recover your energy and physical strength, which will affect your study and life the next day. But don't sleep too much, otherwise it will make people depressed, lazy and unhealthy.

2) Have a suitable learning environment.

A suitable learning environment is conducive to the efficient work of the brain. Delay the arrival of brain cell fatigue. The main thing is to keep the air fresh, the light is suitable and the sitting posture is good. You can open the window properly, keep the air convection, let the brain get enough oxygen, study in soft light instead of dazzling light, reduce visual fatigue and protect your eyesight.

3) Pay attention to the mutual adjustment between study and rest.

There should be time for the brain to rest during the learning process. After studying for an hour, you should get up and exercise, so that the whole body blood circulation is smooth, and let your eyes look far away or do a few eye exercises to keep healthy, which is conducive to eliminating brain fatigue. In addition, arts and sciences can be arranged alternately when studying to prevent a certain area of the brain from working for a long time.

4) Ensure adequate and proper nutrition.

The activities of brain cells need rich nutrients, but brain cells themselves lack the ability to store nutrients, so they should be supplied with adequate and appropriate nutrients every day. Students should eat more foods rich in protein, vitamins and phosphides, such as meat, eggs, beans, fresh vegetables and fruits. There should be no partial eclipse, so that the brain can work efficiently. In addition, some students often skip breakfast, which is very harmful to the brain, because the nutrients in the blood have been consumed a lot after a night. If you don't eat breakfast and study, the blood supply to the brain is very limited. Obviously, brain cells are inefficient and prone to fatigue. Therefore, it is wrong to think that it doesn't matter whether you eat breakfast or not. Teenagers should not only eat breakfast, but also eat well

5) Don't smoke or drink.

Brain cells are very sensitive to toxic substances such as nicotine in alcohol and smoke. Drinking and smoking will not only seriously damage the normal growth and development of teenagers, but also hinder the development of thinking and even lead to premature failure of thinking activities. Therefore, teenagers should put an end to the bad behavior of smoking and drinking.

6) Take an active part in physical exercise.

Physical exercise can promote the sensitivity of the nervous system. Especially for ball games, you need not only abundant physical strength, but also quick response, accurate judgment and rich imagination. Students might as well take part in these sports more.

7) Develop a regular lifestyle.

Regular work and rest habits can save the functional loss of brain cells, thus improving learning efficiency and preventing excessive fatigue.

The human brain is like a machine. Only by using it correctly and caring for it can we create more things and realize its maximum value. May all students have a healthy and intelligent brain.
