Traditional Chinese medicine believes that life is between heaven and earth, and its life activities should be consistent with "life", "growth", "harvest" and "hiding" in spring, summer, autumn and winter. Adjusting your work and rest according to the changes of the four seasons and conforming to nature can improve the quality of sleep and play a good role in health preservation. Go to bed late and get up early in spring: Spring is the season when everything begins to grow, and the qi of heaven and earth begins to sprout in this season, so sleep in spring should be "lying at night and getting up early". The specific sleep time is generally kept around 10: 30 at night. Getting up early in the morning, preferably around 6 o'clock, is conducive to the growth of yang in the body. Summer is the season with the shortest sleep time: everything is at its peak in summer, and so is the human body. As vitality gradually reaches its peak, people's waking time will also increase greatly. Most people can only sleep for five or six hours in summer, so it is more necessary to "lie down at night and get up early" in summer. Unlike spring, because the days in summer are the longest in a year, you should stay up late. 1 1 can sleep around, but the time of getting up early remains the same. Go to bed early and get up early in autumn: If the "life" in spring and the "growth" in summer are better, then in autumn, the human body will reach the most balanced state among the four seasons. At this time, the state of the human body has changed from hyperactivity in summer to introversion in autumn, so it is best to go to sleep early if possible and keep at least 8 hours of sleep every day to facilitate the "collection" of yin essence. Although autumn begins to converge, there is no need to "hide", so pay attention to getting up early when going to bed early to adapt to the relaxation of yang. Go to bed early and get up late in winter: in winter, most animals and plants go into hibernation to save their energy and prepare for next year's growth. The human body should also adapt to the characteristics of nature and reduce activities appropriately, so as not to disturb the yang and consume the yin essence. Go to bed early and get up late this season, and it is best to get up at dawn. However, it is not advisable to get up too late, otherwise the yang spirit will not stretch and rise, which is not conducive to the balance of yin and yang in the body. Although the four seasons have different schedules, "staying up late and getting up late" is a health taboo. Going to bed late and getting up late breaks the law that the human body adapts to natural changes, so staying up late and staying in bed will make the body tired and dizzy. Of course, any kind of work and rest must have a degree, and the overall sleep time is 7~9 hours.
