Some people sleep, like to sleep on their side, to the left, and the right oppresses the left; Right, left oppresses right. People who sleep on their backs press their forechests on their backs, while people who lie prone put back pressure on their forechests. In any case, oppression and being oppressed are related. Some people say that he sleeps standing up, making the upper body oppress the lower body, and the whole body weight is pressed on the soles of his feet, making the oppressed more painful.
So what is the best sleeping position to choose? It depends on personal circumstances. Scientific research says that people had better sleep on the right side, which may be the best sleeping position for human beings, but the best sleeping position is universal. For example, fat people can only choose a sleeping position that is scientifically considered bad-sleeping on their backs. If the fat man sleeps on his side, the whole weight is on his arm, so he won't sleep for long. The fat man sleeps on his back, his huge body is scattered on his broad back, and the oppression of each part is light. Plus, fat people sleep more dead, so they sleep longer.
Thin people can sleep in any position except the left, because the most important organ in the whole body is on the left, and the most important organ can't be oppressed, especially the bigger and heavier people.
To sum up, as long as gravity exists, the relationship between oppression and oppression will always exist. When oppression always exists, we have to choose a relatively comfortable oppression posture to sleep.
Some people say that sleeping in space is not oppressive. I think it's also true. It's just that people who are used to living in the air, once they drift in space and lose their oppressed bodies, sleep is not practical. At that time, they will definitely think that it is better to sleep in bed if the earth is a little more oppressive.

Sleep can slow down all systems in the body, such as slow heartbeat, low blood pressure and low body temperature, which greatly reduces the release of energy, thus achieving the effect of saving energy. At the same time, sleep can promote the release of growth hormone and the activation of various active enzymes. When sleeping at night, the secretion of growth hormone is 5-7 times higher than during the day. It is beneficial to the growth and development of children and adolescents, and can also activate various active enzymes in middle-aged and elderly people, thus accelerating metabolism and delaying brain decline.

Sleep and disease:
1) Some people grind their teeth when they sleep at night, which is related to the decrease of saliva in the mouth and the lack of lubrication on the tooth surface during sleep. However, long-term grinding will wear the enamel on the tooth surface and affect the chewing function. There are many reasons for grinding teeth. Children play unrestrained during the day, disrupting the normal life rules, affecting sleep, and will involuntarily grind their teeth; Being reprimanded during the day can lead to mental stress and fatigue, which makes the part of the brain that manages masticatory muscles in an excited state and keeps chewing. If children can combine work and rest and have a good spirit, the habit of grinding teeth will gradually improve. Some children suffer from ascariasis, because the interference of ascariasis will make the intestinal wall constantly stimulated, and it will also cause the reflex contraction of masticatory muscles to cause molars, and the drugs will disappear after insect repellent. Some children eat indigestible food before going to bed, so that the digestive tract can not be fully rested, and there will be molars.

Drooling during sleep is generally caused by the following factors: 1. Poor oral hygiene: the temperature and humidity in the oral cavity are most suitable for the reproduction of bacteria, and food residues or sugar substances accumulate between the teeth and the tooth surface, which is prone to dental caries and periodontal disease. These bad factors are very irritating, and you will drool when you sleep.
