"Guanzi" pointed out: "Autumn begins in the shade, so everything is harvested." Yin Qi started here, which means autumn. Due to the gradual collection of Yang Qi, Yin Qi gradually grew up. Everything is a harvest, which means that everything is mature and it is time to harvest. Judging from the climate characteristics in autumn, it turns from hot to cold, that is, the transition stage of "Yang disappears and Yin grows". The physiological activities of human body change from "long summer" to "autumn harvest". Therefore, autumn health care cannot be separated from the principle of "nourishing", that is to say, autumn health care must take the maintenance of yin in the body as the primary task. As Huangdi Neijing said: "Nourish Yin in autumn and winter." Nourishing Yin in autumn and winter means nourishing and storing Qi in autumn and winter, so as to adapt to the law that Yin is gradually flourishing in nature, thus laying a foundation for the growth of Yang in the coming year, and should not consume essence and hurt Yin.
Drying is harmful to human body fluids. As the saying goes, "dryness is better than dryness." When body fluids are consumed, there will be dryness, such as dry mouth, dry lips, dry nose, dry throat, dry tongue, constipation, dry skin and even chapped skin. The lung is fine and dirty, and it likes to moisten dryness and hates dryness. When dryness enters the lung, it is most likely to hurt its vaginal fluid. Lung loss of fluid and moistening will inevitably affect its function, so it cannot be reduced. From mild cough to less phlegm, phlegm is difficult to stick. In severe cases, the lung collateral is injured and bleeding, and blood is seen in the sputum. After the lung body fluid is insufficient, it will be difficult to dry without body fluid to help the large intestine.
Autumn is dry, which is divided into warm and cool. It is generally believed that the temperature in early autumn is Shang Gao, so it is warm and dry; The temperature drops in late autumn, so it is cool and dry. No matter whether it is cold or warm, it always shows dry skin and insufficient body fluid. But there are still differences between the two in clinic. Warm dryness is harmful to the body, often manifested as aversion to cold or slight aversion to cold, obvious fever and thin pulse; When cold and dryness hurt people, they often have no fever or slight fever. On the contrary, aversion to cold is more obvious, with numerous pulse conditions.
