In a year, spring grows in summer, autumn harvests in winter, and Huangdi Neijing gives the principle of keeping in good health in four seasons. Only by adapting to the changes of natural phenology can we really achieve reasonable health and longevity.

Winter is the coldest season of the year, with abundant sunshine and abundant yin. Therefore, the way to preserve one's health in winter should pay attention to protecting the yang, focusing on the word "hiding".

Basic rules of keeping in good health in four seasons

The four seasons in nature are characterized by spring, long summer, autumn harvest and winter storage. According to the theory of traditional Chinese medicine, the basic principle of four seasons health preservation is "nourishing yang in spring and summer, nourishing yin in autumn and winter". Therefore, the four seasons diet aftercare should also follow this principle.

The principle of spring diet: it is sour and sweet, and choose spicy and warm products. Diet should be light and delicious, avoid sour, greasy and cold things, and eat more yellow-green vegetables.

Summer diet is hot and sour, less cold and less cold drinks. Choose light, refreshing, less greasy and digestible food. "Summer tonic" should warm yang and adjust yin.

Autumn diet principle: less spicy and more sour, prevent dryness and protect yin. For example, eat less spicy products such as onions, ginger, garlic, leeks and peppers, and eat more sour fruits and vegetables. Eat more sesame seeds, walnuts, honey, glutinous rice and dairy products.

Winter diet principle: reduce salt and increase bitterness, protect yin and suppress yang. Appropriate intake of soft-shelled turtle, soft-shelled turtle, lotus root, flax, fungus, etc. Tonifying in winter should be based on nourishing yin and protecting yang.
