Extended data:

In spring, people's qi and blood flow from the inside out, and the whole nature is also the time when everything is born. Huangdi Neijing said that at this time, we must remember "lying at night and getting up early, walking in a wide court." Sleeping at night means sleeping after dark; Getting up early means getting up early in the morning.

In summer, people are easily agitated and lose their temper. Why is this? Because in summer, qi and blood come outside, and there is a relative shortage of qi and blood inside, it is easy to get angry when something happens. Avoid getting angry in summer, don't lose your temper, or try to lose your temper as little as possible. In summer, people should "stay up late and get up early, and the sun is not tired", that is to say, in summer, we can stay up late, stay up late and get up early, and sleep less, even if you make up some sleep at noon. Before 1 1 at the latest, I have to sleep and get up at five or six in the morning. Simply put, if you follow the sun and follow this natural law, you will help people's yang to grow outward.

In autumn, people's daily life and health preservation can be summed up as "going to bed early and getting up early, having fun with chickens". "Having fun with the chicken" means that our autumn life rules should follow the chicken. As long as the chicken enters the nest, you sleep, and when the chicken comes out, you get up and have fun with the chicken. At this time, your qi and blood are only collected from the outside to the inside. As we all know, people's yang is outside during the day and at night. So if you can go to bed early and get up early like a chicken, then your qi and blood will conform to this state that has been gradually stored in it.

In winter, if you want to "go to bed early and get up late, you must wait for the sun to come out", that is, get up after the sun comes out. When you exercise in winter, you must wait for the sun to come out. Follow the sun. When the sun comes out, you go for a walk. When the sun goes down, you go home. Don't go out to exercise in foggy, dew and snowy weather. This is not in line with the law of TCM health preservation.
