The theories and methods of TCM health preservation are extremely rich, and one of the important principles is "timely health preservation". As "Lost in Soul" said: "Therefore, the health of the wise must be suitable for cold and heat 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 is based on the liver, summer on the heart, long summer on the spleen, autumn on the lung and winter 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 a transitional season from summer to winter. As the saying goes, "the 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 in line with the characteristics of autumn solar terms can we ensure vigorous energy and vitality.

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

"Su Wen Si Qi Diao Ling" says: "Autumn is March, which is called Rongping. The weather is urgent and the atmosphere is clear. Early to bed and early to rise, happiness is with the chicken. Calm the mind, slow down the autumn punishment, converge the air, calm the autumn qi and clear the lung qi. This autumn is the way to raise your income. "

"Autumn March" here refers to the day before beginning of autumn, when the summer heat, white dew, autumnal equinox, cold dew and frost fell to beginning of winter. Huangdi Neijing pointed out that three months in autumn is a calm season, 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, and the cold air in autumn can be peaceful. Do not extinguish the will, and make the lung qi clear. Only in this way can we adapt to the autumn air and adjust the "harvested" air.

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