First, avoid using your brain before going to bed. If you have the habit of working and training at night, do something that consumes your brain first, and then do something more relaxing, which is easy to relax and very easy to fall asleep. Otherwise, if the mind is excited, it is difficult to fall asleep even in bed, and it is very easy to lose sleep after a long time.

Second, avoid eating before going to bed. After a person enters a dormant state, the rhythm of thematic activities in some parts of the human body will gradually slow down and enter a state of rest. If you eat before going to bed, your stomach, liver, spleen and other human organs will be busy again, which will not only increase your pressure, but also make other human organs not get enough rest. The functional division of the cerebral cortex responsible for the digestive tract will also be excited, and it is easy to have nightmares after falling asleep. If you eat too early after dinner and feel hungry before going to bed, you can eat less dessert or fresh fruit (such as bananas, apples, iPhone, etc. ), but after eating, you can rest for at least half an hour before going to bed.

Third, avoid the excitement of people before going to bed. This kind of excitement can easily cause excitement or confusion in the central nervous system, making it difficult for people to fall asleep and even lead to insomnia. Therefore, before going to bed, we should try our best to reduce the anger of exultation or fantasy, and our mentality should be stable. If you have difficulty sleeping because of nervousness, anxiety or excitement, please take a prone position, put your hands under your navel, lick your palate with your tongue, relax yourself, and keep swallowing body fluids when you are thirsty. After a few minutes, you will fall into a sweet sleep.

Fourth, avoid talking before going to bed. As the saying goes, food does not speak, sleep does not speak. Because people are very excited when they talk, their brains are wide open, which will endanger the quality of sleep. Therefore, people should not talk much before going to bed.

5. Avoid sleeping face up. In the past, it was best to lie on the right side, so that the whole body naturally relaxed, and it was very easy to fall asleep and relieve fatigue. Lying flat will make the bones and muscles of the whole body in a state of excessive tension, which is not conducive to relieving fatigue, and it is very easy to cause nightmares and lead to sleep because of inhalation in the hands and chest.

Sixth, avoid sleeping with your mouth open. Sun Simiao said: Sleeping at night is often a habit of keeping your mouth shut, which is also the best way to maintain your vitality. Sleeping with your mouth open is very easy to be eroded by viruses and bacteria in the air, which not only prevents problems before they happen, but also easily stimulates the lungs and stomach by strong cold air and dust, thus causing diseases.

7. Avoid sleeping with your face covered. Some people always like to sleep with their faces covered. In that case, you will inhale a lot of carbon dioxide and lack the necessary o2, which is extremely unfavorable to your physical and mental health.

Eight, avoid sleeping when sleeping. Don't let the wind coming in through the window gently blow overhead. Because people's adaptability to external conditions is reduced to a certain extent after falling asleep, if they sleep in the wind for a long time, strong cold air will invade from the capillaries on people's skin, thus causing fever, cold, stroke and facial paralysis.

Nine, avoid sleeping in front of the lamp. When people are asleep, although their eyes are closed, they can still feel bright. If they sleep in front of the lamp, the lighting effect will disturb the natural balance in the human body, leading to more and more uncoordinated body temperature, heartbeat and blood pressure, which makes people feel uneasy and difficult to fall asleep. Even if they fall asleep, they will wake up easily. If you do that, your body will be too hot and prone to sores, boils and other diseases. Getting up at night to go to the toilet is also easy to catch cold, causing fever and cold. It is worth mentioning that if you use a coal stove for heating, you should pay attention to ventilation to prevent carbon monoxide poisoning.
