What role does sleep play in the human body?

Some people, relying on their youth, often do everything they can to play, and may even stay up all night; some people, in order to rush their work, often stay up all night; and some people, due to neurasthenia, menopause and other problems, also suffer from very poor sleep quality. So, if you often don't sleep or your sleep quality is often poor, what harm will it do to the human body? So, let's take a look at what role sleep plays in the human body:

immunity

Enhance disease resistance

People are always particularly sleepy after being sick, because the body uses sleep to suppress other physiological functions, highlight immune function, and help the body recover health as soon as possible. This shows that adequate sleep can enhance human immunity. Medical experiments have also found that if a person reduces their sleep by 4 hours, the activity of immune cells in the body will be weakened by 28%; but they can recover after getting enough sleep.

endocrine

Regular secretion of hormones

During sleep, various hormones that are regularly secreted play an active role. Take growth hormone as an example. When you enter deep sleep for one hour, its secretion reaches its peak, which is more than three times that of the daytime. In addition to promoting growth, this hormone can also accelerate the burning of fat in the body. On the contrary, if there is a lack of sleep, endocrine disorders and irregular hormone secretion, not only will the mood become easily agitated, but it may also affect fertility.

skin

Nurturing beauty

The metabolism of the skin is most active during sleep. Because when you fall asleep, the consumption of muscles, internal organs, etc. is reduced, and their blood vessels are in a relatively bottleneck state, while the skin blood vessels are completely open, and blood can fully reach the skin, providing it with nutrition, self-repair and cell renewal, thereby delaying skin aging. If you miss "sleep", the best time to nurture beauty, your skin will easily become dry, rough, dull, and wrinkled, especially dark circles around the eyes.

A good sleep can not only enhance the body's disease resistance, normalize the body's endocrine system, and make the skin more beautiful; it can also promote brain rest, enhance the brain's memory signals, and improve memory; make hair darker and shinier, reduce the occurrence of problems such as hair loss and gray hair; and reduce the pathology of internal organs.
