As early as Huangdi Neijing, the four-season health preservation was expounded. For example, the chapter "Soul Pivot and Five Kinds of Body Fluids" in Neijing said: "In summer, the clothes are thick, so the sweat is closed ... When it is cold, the air will be closed, and if the water is naked, it will be drowned and angry." This means that in spring and summer, qi and blood are very easy to be inconsistent, mainly manifested as facial relaxation, depression and sweating. In autumn and winter, the collection of personal qi and blood tends to be adducted, which is mainly manifested in high skin density, less sweating and more drowning, in order to maintain and regulate the unity of man and nature.
Even the skin changes with the seasons, not to mention other parts of the human body. Therefore, everyone's health care development strategy for one year should be adjusted accordingly with the changes of the four seasons. In short, it is to be timely.
Keeping in good health according to law means keeping in good health with the weather. To be practical, it is the health standard of hot weather and cold weather in winter. The general principle is to conform to nature and preserve one's health, that is, to adjust one's body according to the transformation of yin and yang in nature. The core idea of legal health care is four-season health care, which is based on the changes of cold, heat and cold in spring, summer, autumn and winter.
Health preservation according to the four seasons, that is, health preservation in four seasons, that is, conditioning according to the laws and characteristics of climate yin and yang changes throughout the year, in order to achieve the purpose of health preservation and longevity. To understand the meaning of four seasons health care, it is necessary to understand the concept of the ups and downs of yin and yang in four seasons health care in traditional Chinese medicine. Ancient Chinese medicine believed that the changes of heat, cold and cold throughout the year were caused by the ups and downs of yin and yang in a year. The winter solstice solar term is the whole process from spring to summer, so there are spring temperatures and summer heat; Yin Chang Yang Xiao is the whole process from autumn to winter, so autumn is cool and winter is cold.
Throughout the year, it is sunny in spring and summer and cloudy in autumn and winter. Of course, with the change of climate, festivals will also produce changes in spring and summer, harvest and winter storage. According to this understanding, the four-season regimen in TCM stipulates that people should regulate qi and blood in spring and Xia Zhishi, and maintain yin in autumn and winter. Therefore, since ancient times, there has been a saying that "Yang is nourished in spring and summer, and Yin is nourished in autumn and winter".
This requires everyone to make appropriate adjustments according to the changes of the four seasons, such as spiritual theme activities, daily routine, and five flavors of diet. In the schedule of work and rest, we should also adapt to the changes of the four seasons, and ensure "regular living" and "going to bed late and getting up early" in spring and summer, "going to bed early and getting up early" in autumn and "going to bed early and getting up late" in winter. The intake of five flavors in the diet should be more regular. Excessive drinking, satiety or partial eclipse can damage the internal organs and endanger physical and mental health. Vegetables, fruits, melons and fruits are also taken regularly. In addition, "the five internal organs should have their private income at four o'clock." According to the climate characteristics of the four seasons, people also summed up the five-organ conditioning methods of nourishing the liver in spring, nourishing the spirit in summer, nourishing the spleen in summer, moistening the lungs in autumn and protecting the kidney in winter.
