In Huangdi Neijing? Su Wen? Four Qi Tunes the Spirit: Sages nourish Yang in spring and summer, and Yin in autumn and winter, so as to follow their roots, while those who go against them will suffer, and those who go against them will not tolerate serious diseases, which is called the way. The meaning of this sentence is that people who know how to keep in good health should raise yang in spring and summer and yin in autumn and winter to abide by this fundamental principle. If this is violated, life will pay a price and diseases will occur; If you can abide by it, the disease will not happen. This is the so-called four-season sleep regimen.

It is advisable to sleep at night in spring. Photographic news said: "Spring March, this is called Chen. Heaven and earth are born and everything is glorious. Go to bed at night, get up early, stride to court, and be delayed to make a living. " People's daily routine is consistent with sunrise and sunset. Spring is the season when everything revives. People should also go to bed early and get up early, and do some relaxing sports in spring, such as Tai Ji Chuan and gymnastics, to breathe fresh air. It is best to go to places with green trees and grass to accept the "qi of heaven and earth", so as to conform to the natural law of spring.

However, we should also pay attention to two health-preserving misunderstandings:

First, some people think that the earlier you get up, the better. Some people even get up in the morning to do morning exercises, which is actually not desirable. Because the body's biological clock is in a "rest state" at this time, forcing it to do morning exercises will lead to the disorder of the biological clock.

Secondly, green plants breathe at night, discharging carbon dioxide and inhaling oxygen. Only when the sun comes out can they breathe out oxygen through photosynthesis. Exercise is good for your health at this time. If you get up too early to exercise, you will easily inhale a lot of carbon dioxide, which will lead to physical discomfort, while getting up too early and the temperature is too low will easily catch a cold.

In summer, you should stay up late and get up early. In summer, your heart is full of fire and your lungs are failing. Therefore, we should go to bed late and get up early, conform to nature and maintain yang. Huangdi Neijing? Su Wen? "Four Seasons Theory" said: "Going to bed late and getting up early is not enough."

Sleeping late in summer can adapt to the lack of natural yin; Getting up early can adapt to the sun be the spirit. In summer, the sun rises early, and the air is fresh in the morning. Getting up early for outdoor activities is quite beneficial to strengthening physical fitness, and the sleep time in summer is short, so it is necessary to take a proper nap to help the body recover.

Don't worry before going to bed. Recalling some pleasant things can not only have a good sleep, but also effectively overcome the hot interference. Don't smoke before going to bed, because nicotine will interfere with normal sleep, and drinking will also destroy the blood circulation of the human body and make people insomnia. After waking up, you should "lie in bed" for 5 minutes, because various biological clocks will gradually wake up; Secondly, many biological clocks change from slow to fast at this time, which requires a process.

Early to bed and early to rise in autumn? Su Wen? "Four Qi Tiaoling" says: "In autumn and March, lie down early and get up early, and have fun with chickens." In other words, go to bed early and get up early in autumn. Going to bed early conforms to the harvest of yin essence and nourishes the gas of collection; Get up early to adapt to the relaxation of yang, so that lung qi can be stretched. If you violate it, it will damage your lungs and make you sick easily in winter.

Relevant personnel have studied the onset time of ischemic diseases such as cerebral thrombosis, and found that the incidence rate of such diseases is high in autumn, and the onset time is mostly in the late stage of long sleep. If you get up early in autumn, you can reduce or shorten the chance of thrombosis, which is of certain significance to prevent thrombosis.

It is more appropriate to go to bed early and get up late in winter. Huangdi Neijing holds that keeping in good health in winter should be "going to bed early and getting up late, waiting for the sunshine". In the Qing Dynasty, Shi warned people in the Health Mirror that "when the water is closed in winter and March, it is appropriate to stick mandarin ducks to nourish the true qi". Traditional Chinese medicine believes that human life is closely related to nature, and people's daily life can only be healthy if they conform to the changes of yin and yang in the four seasons.

Winter is the season when all life lurks and hides. People should not disturb the spirit of the sun. They should go to bed early and get up late, and it is best to wait until sunrise, so that their will is as quiet as an ambush, to keep warm from the cold and not to make their skin sweat. Otherwise, it will damage the kidney qi, and it will be easy to be paralyzed next summer.
