The theories and methods of health preservation in traditional Chinese medicine are extremely rich, and one of the important principles is "keeping health in time". As "Soul Pivot, the God" said: "Therefore, the health of the wise must be suitable for cold and summer at all times ... If so, the eccentric evil will not come, and you will live a long life." Zhang Jingyue, a medical scientist in the Ming Dynasty, said: "Spring should be based on the liver, summer should be based on the heart, long summer should be based on the spleen, autumn should be based on the lungs, and winter should be based on the kidney." It shows that the physiological activities of the five internal organs of the human body must adapt to the changes of yin and yang in the four seasons in order to maintain a harmonious balance with the external environment.

Autumn is the transitional season from summer to winter. As the saying goes, "one layer of autumn rain is cool", the summer heat gradually recedes, the autumn is crisp, the wind is high and things are dry. At this time, the general principle of health preservation is "nourishing yin in autumn and winter". Only by conforming to the characteristics of autumn solar terms can we ensure vigorous energy and vitality.

1. Raising "harvest" in autumn has a long history.

"Su Wen, Four Qi Tunes the Spirit" says: "Autumn is March, which is called Rong Ping. The weather is urgent and the atmosphere is bright. Early to bed and early to rise, is happy with chickens. Calm the mind, slow down the punishment in autumn, converge the air, make the autumn gas calm, and make the lungs clear. This autumn gas should be the way to raise and collect. "

"Autumn March" here refers to the day before beginning of autumn, Chushu, Bailu, Autumnal Equinox, Cold Dew and Frost fell to beginning of winter. Huangdi Neijing pointed out that three months in autumn is a season of calm and calm, the weather is getting colder and the atmosphere is clear. People should go to bed early and get up early, which can be based on the work and rest of chickens. The spirit must be quiet, not anxious or impatient, so that the cold air in autumn can be peaceful. Do not make the will go out, and make the lung qi clear and even. Only in this way can we adapt to the autumn air and recuperate the "harvest" air.

"Guanzi" says: "Autumn begins with yin, so everything is harvested". The word "harvest" in the sentence contains two meanings: one refers to the harvest season when everything is ripe and the fruits are numerous; Second, it refers to the autumn when thousands of trees fall into English and thousands of flowers wither, which is the season of gathering. Judging from the climate characteristics, the early autumn is called "autumn tiger" because of the lingering summer heat and the raging autumn sun, and the climate characteristics are that the temperature is still high. However, after the Millennium, the cold in the north gradually went south, the autumn wind rustled, the climate gradually changed from hot to cold, and the temperature difference between morning and evening was large, and everything gradually fell with the increase of cold. At this time, we must pay attention to maintaining the yang in the memory in autumn health preservation, and all the adjustments of spirit, daily life, diet and exercise must follow the principle of "receiving".
