The essence of seasonal health preservation is to adjust the functions of various parts of the human body according to the laws and characteristics of yin and yang changes throughout the year, so as to achieve the purpose of health and longevity. For example, nourishing yang in spring and summer with the growth of yang, and nourishing yin in autumn and winter with the collection of yin, which is what we usually call "nourishing yang in summer and nourishing yin in autumn and winter", is an important principle of health preservation formed on the basis of seasonal health preservation.
The third month of spring is the season of recovery of all things, and nature is full of vitality. So everything in nature is thriving. At this time, people should stay up late and get up early. After getting up, go to the courtyard, let your hair hang freely, wear spacious clothes, don't bind your body, and let your spirit be relaxed and lively with the growth of everything in spring. This is the law and method of keeping in good health in spring.
Summer health rules In the three months of summer, everything grows luxuriantly, so it is called numerous and beautiful. Heaven and earth are connected with yin and yang, and plants blossom and bear fruit. At this time, people should go to bed late and get up early, never hate the long days, keep a good mood, make the flowers of spirit more beautiful, make the yang flow smoothly, and have a strong interest in foreign things. This is the law and method to adapt to summer health.
In the three months of autumn, nature presents a scene of bumper harvest and peace. The autumn wind is vigorous, the autumn is crisp and the scenery is beautiful. In this season, people can follow the rules of chicken's life, go to bed early and get up early, so as to promote mental peace, reduce the damage caused by the cold in early autumn, restrain their mental mood without spreading it outside, calm the autumn air and clear the lung air. This is the method and principle that is suitable for autumn and can keep the human body "closed".
The law of keeping in good health in winter The three months of winter are the season when vitality lurks and everything hides. The sun in nature is deep and the cold is strong. It's freezing, the water freezes and the earth cracks. At this time, people should go to bed early and get up late, and get up when the sun rises, so as to make their spirit calm and not move. Just like lurking, try to keep warm and don't sweat too much, which is a health care method and principle to adapt to the characteristics of "hiding" gas in winter.
Huangdi Neijing holds that heaven and earth move endlessly according to the law of the ups and downs of Yin and Yang in the four seasons, and our health care must be adjusted in time according to this law. Violation of this law will inevitably lead to imbalance between yin and yang in the body and make the body sick.
