The effect of sleep on the human body: (1) Eliminate fatigue. Reserve energy substances and restore energy. After working and laboring during the day, the human body consumes a lot of substances and energy. People will feel very tired. Sleep can make people quickly eliminate fatigue, so that the body can be fully rested, so as to restore physical strength and energy. At the same time, the synthesis and storage of fat, glycogen, protein, etc. are significantly increased during sleep, and these energy substances are stored to prepare for future activities. Therefore, sleep can store energy substances, which is conducive to restoring physical strength and energy.

(2) Protecting the brain During sleep, because the whole body is in a state of inhibition, the metabolism of the brain decreases, and the oxygen consumption of the brain decreases, so that the brain can get full rest and function recovery. In addition, the protective function of the blood-brain barrier, a barrier between brain tissue cells and the blood supplying the brain, is strengthened during sleep, making it difficult for bacteria or other harmful substances in the blood to enter the brain through the blood-brain barrier, so that the The brain is protected. (3) Consolidate memory and promote intellectual development. Sleep plays a role in processing and integrating the information obtained during the day, and the whole sleep is related to memory.

The brain has about 10 billion to 15 billion nerve cells, also known as neurons. They have many tiny protrusions, namely "synapses", through which neurons establish intricate connections with each other and communicate information. During the process of human learning and memory, new synaptic connections are constantly established between neurons. During sleep, the synthesis of brain proteins increases, which is conducive to the establishment of new synaptic connections, thereby promoting the development and development of memory and brain function.

Adequate sleep helps consolidate memory, promote intellectual development, and ensure that brain functions, such as thinking ability and language ability, are in a good state. (4) Promote growth and development During deep sleep, the pituitary gland secretes growth hormone, and its secretion is positively correlated with the length of deep sleep. Growth hormone mainly promotes the synthesis of nucleic acid and protein, participates in the metabolism of gluten and fat, increases the volume and number of cells, promotes bone development, and makes the body grow taller.

Therefore, children's growth and development speed is accelerated during sleep. Practice has proved that the growth rate of infants and young children in the sleep stage is more than 3 times faster than that in the non-sleep stage. Therefore, adequate sleep is particularly important to ensure the growth and development of children.

(5) Enhancing the body's immune mechanism. When promoting disease recovery and sleep, the body's immune system is trimmed and strengthened to a certain extent, the cells with immune function in the body and the immune active substances produced by them increase, and the ability to produce antibodies increases. When exogenous harmful substances invade the human body, these cells and substances with immune function will trigger a series of immune responses to remove pathogens, and play the role of immune defense and immune repair for the body. For the sick, after sleep, the immunity is enhanced, that is, the body's resistance is enhanced, which undoubtedly speeds up the recovery process of the disease.

(6) Maintain mental health, slow down aging, help to maintain adequate sleep, and help maintain the balance of yin and yang in the human body. "The Yellow Emperor's Classic of Internal Medicine" said two words: "Yin and yang are secret, and the spirit is the rule." It means that the yin and yang are balanced, and the spirit can be healthy.

The harmony of yin and yang is a regimen of health preservation, which is conducive to maintaining mental health, delaying aging, and promoting longevity. Lack of sleep can easily lead to a series of physical and mental symptoms. In the short term, it is manifested as fatigue, inability to concentrate, and irritability. Long-term lack of sleep is prone to emotional instability, anxiety, irritability, and even memory, thinking ability and physical function decline. Adequate sleep can also prevent the occurrence of cancer.

Because the peak of human cell division is after sleep, improving sleep quality and adequate sleep can ensure the normal division of human cells. What are the effects of long-term late sleep or lack of sleep and poor sleep quality on the body? 9:00 pm to 3:00 am is the time to nourish the liver and gallbladder. If a person does not sleep for a long time (23:00-1:00), it will damage the gallbladder and the liver.

The initial symptoms are dark circles under the eyes, dry eyes, tiredness, sunken eyes, dizziness, headache, mental fatigue and inability to concentrate. 1. Eye diseases: The liver opens in the eyes, and not sleeping during childbirth can easily lead to liver deficiency, blurred vision, presbyopia, tearing in the wind, and other eye diseases such as glaucoma, cataract, fundus arteriosclerosis, and retinopathy. (So ​​problems with the eyes are usually caused by problems with the liver.) 2. Bleeding symptoms: the liver has the function of storing blood and regulating blood. Subcutaneous bleeding, bleeding gums, fundus bleeding, ear bleeding and other bleeding symptoms.

3. Diseases of the liver and gallbladder: the gallbladder needs to replace the bile when the child is born. If the person does not sleep when the gallbladder meridian is prosperous, the replacement of the bile will be unfavorable. If it is too thick, it will crystallize into stones, and gallstones will occur over time. At present, there is one hepatitis B virus carrier in about 5 people in Guangzhou. Most of them are caused by not going to sleep when the child goes against the law of nature. Carrying hepatitis B virus means that 40%-60% of them will have liver cirrhosis in the future, and severe liver cancer will be formed.

4. Emotional diseases: not sleeping during childbirth is easy to consume courage and qi. The "Huangdi Neijing" says "Qi strengthens courage". When courage is deficient, people tend to be vigilant, suspicious, and timid. Over time, depression and anxiety may develop. Symptoms and other emotional problems, and even misanthropy and suicide. Nowadays, more and more teenagers suffer from depression and even commit suicide, mostly because they often stay up late and damage the liver and gallbladder. (So ​​depression, anxiety, etc. cannot just look for psychological factors, and psychological abnormalities often come from physiological imbalances).
