The importance of sleep can be summarized as follows:
(1) Eliminate fatigue and restore physical strength: Sleep is the main way to eliminate physical fatigue. Because of the function of gastrointestinal tract and its related organs in sleep, human energy substances are synthesized and manufactured for activities. In addition, due to the decrease of body temperature, heart rate, blood pressure, respiration and some endocrine, the basal metabolic rate is reduced, so that physical strength can be restored.
(2) Protect the brain and restore energy: People who lack sleep show irritability, excitement or listlessness, inattention and memory loss. Long-term lack of sleep can lead to hallucinations. People who get enough sleep are energetic, quick-thinking and efficient. This is because the oxygen consumption of the brain is greatly reduced during sleep, which is beneficial to the energy storage of brain cells. So sleep is good for 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 invasive antigen substances and remove them through immune reaction to protect human health. Sleep can enhance the body's ability to produce antibodies, thus 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 to help patients through the most painful period, which is conducive to the rehabilitation of diseases.
(4) Promoting growth and development: Sleep is closely related to children's growth and development. After the baby is born, the brain continues to develop for a long time and cannot be separated from sleep; And children grow faster during sleep, because plasma growth hormone can maintain a high level for several hours during sleep. Therefore, it is necessary to ensure that children get enough sleep and ensure their growth and development.
(5) Delaying aging and promoting longevity: In recent years, many investigation and research data show that healthy and long-lived elderly people have good normal sleep. Human life is like a burning flame. Regular burning makes life last. If it burns up and down, it will shorten the time and make people die young. Sleep time is like minimal flame burning, so it can delay aging and ensure longevity.
(6) Protecting people's mental health: Sleep is very important for protecting people's mental health and maintaining normal mental activities. Because of poor sleep for a short time, there will be inattention, and after a long time, it will cause abnormal situations such as unreasonable thinking.
(7) Conducive to skin beauty: During sleep, skin capillary circulation increases, and its secretion and clearance process are strengthened, which accelerates skin regeneration, so sleep is conducive to skin beauty.
