About one-third of a person's life is spent in sleep, and the importance of sleep to the human body is self-evident. When people sleep, not only the body is recovering energy, but also organs such as internal organs and brain are being "repaired". As early as the Qing dynasty, a famous doctor pointed out that "sleep should be the first thing to keep in good health". Sleep can restore essence, nourish qi, strengthen spleen and stomach and strengthen bones and muscles. Sleep is so powerful that you can sleep better and live longer.

We often say that "medicine is not as good as food, and food is not as good as sleep". The ancients also said, "It is better to sleep alone for one night than to take ten kinds of medicine." Good sleep can help the body adjust its physiological function and restore its physique and state, which is not only beneficial to the human body.

Enhance immunity: Studies have shown that when the sleep time is reduced from 7 hours to 4 hours, the immunity decreases by 50%, and when staying up late, the activity of immune cells decreases by 28%. During deep sleep, T lymphocytes and B lymphocytes in the blood increased significantly. Good sleep can enhance the body's ability to produce antibodies, thus improving the body's resistance to diseases.

Promote human growth and development: For children and adolescents, a good sleep can promote the secretion of growth hormone, and for adults, it can also promote the synthesis of protein, which is conducive to the repair of body tissues.

Delaying brain aging: most brain cells are at rest during sleep, which also makes nerve cells get energy supplement, which helps to restore brain function, enhance memory and delay brain aging.

Sleeping has so many benefits. The best sleeping position is to sleep on the left as far as possible, rather than lying on the right or lying flat, which is better for your health.
