According to the change principle of the four seasons in Zhouyi, Neijing puts forward the rhythm of the birth, growth, harvest and hiding of the four seasons to guide people to keep healthy and get rid of diseases. "Neijing Lingshu Shunqi is divided into four seasons" says: "Spring grows in summer, autumn harvests in autumn, and winter storage is normal, so people should also respond." Neijing —— The Theory of Four Qi Regulating Spirit reminds people to adjust their spirits according to the changing characteristics of "four Qi" in spring, summer, autumn and winter, so as to achieve the purpose of health preservation and disease prevention, which points out:
In order to stay healthy and adapt to the spring climate, people can go to bed late, but get up early. You can take a slow walk in the yard in the morning. Pay attention to spreading your hair and loosening your clothes, so that your body can stretch and your will can move with the development of spring. This is the way to adapt to spring. If you violate this principle, you will damage your liver qi and catch a cold easily.
It is hot in summer, so people should go to bed late and get up early. Don't hate the long days and hot weather in summer. They should be cheerful and energetic, so that the yang in their bodies can be released to adapt to the sunny environment in summer. This is a way to keep fit in summer. If you violate this truth, you will destroy your mood and get malaria easily in autumn.
In autumn, people should go to bed early and get up early, eliminate all kinds of external interference, keep comfortable and quiet, get up in the morning to crow, keep convergence and not be exposed to the sun, and clear the lungs. This can adapt to the way of health preservation in autumn. If not, lung qi will be damaged, and diarrhea that is difficult to treat will appear in winter, thus weakening the adaptability of the human body to winter.
In winter, we should pay attention to protecting the spirit of the sun, go to bed early and get up late to bask in the sun, keep good spirits and don't disturb the spirit of the sun. At the same time, we should pay attention to keep warm, avoid cold, and don't make the skin sweat excessively, which will lead to frequent consumption of yang in the closed area. This is a way to keep fit in winter. If this principle is violated, it will damage the kidney qi, and in the spring of the following year, there will be paralysis with weak hands and feet and fear of cold.
According to the above, it is not all right to go to bed early and get up early, but it should change according to the changes of the four seasons. Man is a spiritual thing between heaven and earth and a part of nature. Of course, he should conform to nature for his own maintenance.
In addition, Zhouyi emphasizes the unity of form and spirit, that is, the unity of form and spirit. The so-called form refers to the material basis; The so-called god refers to the external expression of spiritual consciousness, thinking and life activities. God cannot exist independently without the body. If he is strong, he must be full of energy and have normal physiological activities. High spirits can also promote good health. Even if you are sick, Chinese medicine emphasizes keeping a healthy attitude. The Book of Changes-No False Gua says: "No false disease, no medicine, no happiness." It means that if you are sick, don't think about it, just calm down and don't take medicine. This is needed for psychological conditioning after illness, and good and stable psychology plays an important role in the early recovery of the disease.
