The importance of sleep, the protection of the body

For various reasons, young people nowadays are accustomed to staying up late, but have you ever thought about the serious consequences of irregular work and rest? We all know that adequate sleep is the prerequisite for ensuring health and study life, so do you all understand the importance of sleep? Let us take a detailed look at the importance of sleep.

The role of sleep:

1. Eliminate fatigue and restore physical strength: Sleep is the main way to eliminate physical fatigue. Sleep is a good time for the gastrointestinal tract and its related organs to synthesize and produce energy substances for the human body to use during activities. In addition, due to the decrease in body temperature, heart rate, blood pressure, breathing and some endocrine system, the basal metabolic rate is reduced, thereby restoring physical strength.

2. Protect the brain and restore energy: People who lack sleep will show symptoms of irritability, excitement or mental fatigue, lack of concentration, memory loss, etc.; long-term lack of sleep will lead to hallucinations. People who get enough sleep are energetic, quick-thinking and efficient. This is because the brain's oxygen consumption is greatly reduced when it is asleep, which is beneficial to the storage of energy in brain cells. Therefore, sleep is beneficial to protecting the brain and improving brain power.

3. Enhance immunity and restore the body: Under normal circumstances, the human body can produce antibodies against various invading antigens and eliminate them through immune response to protect human health. Sleep can enhance the body's ability to produce antibodies, thereby enhancing the body's resistance; at the same time, sleep can also accelerate the self-healing of various tissues and organs. In modern medicine, sleep is often used as a treatment method to help patients get through the most painful period and facilitate recovery from the disease.

4. Promote growth and development: Sleep is closely related to children's growth and development. The brain of infants and young children continues to develop for a long time after birth, and this process cannot be separated from sleep. Children's growth rate increases faster during sleep because plasma growth hormone can be maintained at a high level for several hours during sleep. Therefore, children should be guaranteed adequate sleep to ensure their growth and development.

5. Delay aging and promote longevity: In recent times, many survey and research data have shown that healthy and long-lived elderly people all have good and normal sleep. Human life is like a burning flame, and if it burns regularly, life will be long; if it burns high and low, the time will be shortened and people will die young. Sleep time is like the minimum burning degree of a flame, so it can delay aging and ensure a long life.
