"Nourish yang in spring and summer, nourish yin in autumn and winter" is an important principle of traditional Chinese medicine health care, derived from the "Huangdi Neijing", which emphasizes following the laws of nature to maintain the body. In spring and summer, when yang energy rises, it is necessary to pay attention to warming and replenishing yang energy, preventing heatstroke and removing dampness; in autumn and winter, when yin energy becomes stronger, it is advisable to nourish yin, moisturize dryness, and consolidate the essence. This article will focus on this theme and analyze its connotation, specific methods and practical significance at different levels.

In spring and summer, the yang energy in nature is strong and the body's metabolism accelerates. At this time, nourishing yang helps to enhance resistance. Specific methods include: moderate exercise (such as morning exercises, Baduanjin) to promote Yang Qi, and eating more pungent and warm foods such as ginger, onions, and leeks in the diet to avoid excessive craving for cold. For example, "Compendium of Materia Medica" records that ginger "dispels cold and warms the body" and is suitable for dispelling dampness and cold in the body in spring and summer. In addition, to prevent heatstroke and dampness in summer, you can drink mung bean soup or adzuki bean and barley porridge to help eliminate dampness.

In autumn and winter, the climate turns cooler and drier, the human body's yang energy is restrained, and nourishing yin becomes the focus. It is advisable to choose yin-nourishing ingredients such as white fungus, lily, and yam in your diet. For example, "Eating Lily in Autumn" recommends "eating lily in autumn to moisten the lungs and dryness." In terms of daily life, you should go to bed early and get up late, and avoid sweaty exercises to prevent the leakage of yang energy. In winter, you can also use moxibustion on Guanyuan, Zusanli and other acupoints to warm and nourish the spleen and kidneys. However, you need to pay attention to the differences in physical constitution, and use it with caution in those with yin deficiency and excessive fire.

In modern life, you can choose health products based on this principle. For example, some pharmaceutical companies produce donkey-hide gelatin cake (Dong'e donkey-hide gelatin) and Liuwei Dihuang pills (Tong Ren Tang), which are suitable for nourishing yin in autumn and winter; in summer, Huoxiang Zhengqi water (Guangzhou Pharmaceutical Group) can be used to remove dampness and relieve heat. However, it should be noted that these products need to be used based on syndrome differentiation and cannot be blindly supplemented. The following table lists some related products and their effects:

In summary, "nourishing yang in spring and summer, nourishing yin in autumn and winter" is a specific practice of the theory of "correspondence between nature and man" in traditional Chinese medicine. Diet, exercise and lifestyle need to be adjusted according to seasonal characteristics. Whether it is ancient health-preserving methods or modern products, the core is to follow nature and provide nourishment based on syndrome differentiation. Quoting the original text of "Huangdi Neijing·Suwen": "The yin and yang of the four seasons are the foundation of all things." It reminds us that health care must follow the laws of nature in order to achieve a healthy state of yin and yang balance.
