9 pm to 5 am is an effective sleep time. People and plants are creatures. During the day (5: 00 a.m. to 2 1 p.m.), they generate energy, and at night (2 1 p.m. to 5: 00 a.m.), they start cell division and transform energy into new cells. This is the time for human cells to recuperate and innovate, and it is also the time for people and the earth to deviate from the sun. Yin governs quietness, which is a good time for people to sleep. Only by resting at this time can they have a good state of mind and body. This is the same reason that babies who sleep more gain weight quickly and children who love to sleep are stunted.
Sleep is a major function of health preservation, that is, replacing rotten cells with a large number of healthy cells. If you can't sleep all night, you can't replace new cells. If one million cells die during the day and only 500,000 cells are recovered in one night, then your body will lose. Over time, people will chaff, just like chaff radish. Why are there centenarians in the world? Because they go to bed on time at 2 1 every night.
Plants absorb the energy of sunlight and grow at night, so you can hear the sound of jointing of rural crops at night. People and plants are both creatures, and the cycle of cell division is roughly the same. If you miss the good opportunity to sleep at night, the regeneration of cells will be far behind the death, and people will get old or get sick prematurely. If people want to let nature take its course, they must follow the sun, that is, they will wake up and sleep. Man is as small as dust in front of the sun. "Anti-sun" is a foolish choice. Sooner or later, they will be pushed down by the great gravity of the sun. This is an objective fact.
Second, sleep and disease.
Modern living habits and lifestyles have brought many negative effects on people's health, resulting in "four major diseases": fruit disease, refrigerator disease, TV computer disease and staying up late disease. The liver has a characteristic: lying down to return blood and sitting up to supply blood.
Midnight (23: 00- 1: 00), in fact, 23 o'clock is the beginning of a new day, not 0 o'clock, which is our misunderstanding. The gallbladder family, the gallbladder meridian opens at 23 o'clock. Not sleeping will hurt your gallbladder. Because eleven zang-fu organs depend on gallbladder, your gallbladder is weak, your whole body's viscera function declines, your metabolism and immunity decline one after another, and your body's function is greatly reduced. Your gallbladder supports the central nervous system and is prone to various mental diseases, such as depression, schizophrenia, obsessive-compulsive disorder and fidgeting.
When ugly, the liver meridian is the most prosperous, and when ugly (1: 00-3: 00), the liver can't remove toxic substances and produce fresh blood. Because of the unfavorable blood storage, the face is blue, and it is easy to get various liver diseases after a long time.
Third, the method of sleep
Sleep methods vary from person to person. There are three ways:
1, simply leg press before going to bed, then naturally sit on the bed, put your hands on your legs, and breathe naturally, feeling your whole body pores open and close with breathing. If you can yawn with tears, the effect is the best. When you want to sleep, sleep on your stomach.
2, lie on your back, breathe naturally, feel breathing like spring breeze, first melt the big toe, then melt the other toes, and then the feet, calves and thighs gradually melt. If you are not asleep, do it again from the beginning.
3. People who fall asleep quickly can lie on their right side and hold their right ears with their right hands. The right palm is fire and the ear is water, forming water.
