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.

Essentials of health preservation in winter

In winter and March, this is called closing Tibet. Water and ice lie on the ground, don't disturb the sun, lie early and get up late, and wait for the sun, so if there is selfish intention, if there is, it will be warm when driving away the cold, and it will not leak the skin and make the gas lose. This winter air should be the way to raise Tibet; In turn, it hurts the kidney, and it is flaccid and soft in spring, and there are fewer people born.

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

Psychological adjustment: You should meditate and control your emotional activities, so as to ensure that the normal physiology of yang in winter will not be disturbed. This can "not disturb the sun" and save physical strength, which is conducive to the emergence of yang in the next spring and the prevention of spring fever.

Exercise principle: Although it is cold in winter, we should keep exercising. Avoid exercising in strong winds, severe cold, heavy snow and foggy weather. Be prepared before exercise, pay attention to appropriately increase or decrease clothes before and after exercise, and don't wear wet clothes to prevent colds.

Dietary principle: winter diet should follow the principle of "nourishing yin in autumn and winter", not cold or dry. It is most suitable for eating a diet with high calorie, nourishing yin and suppressing yang. Winter is the best time for tonic. At this time, the function of spleen and stomach is more vigorous, which is the best time for nutrient accumulation, which is the significance of winter storage.
