Huangdi Neijing says: "Nourish yin in autumn and winter, and nourish yang in spring and summer". Speaking of heatstroke prevention and health care this summer, we should start with people and nature. "Chinese medicine health is closely related to the four seasons, so-called spring, summer, autumn and winter. According to the concept of traditional Chinese medicine, man and nature are interlinked, and life and death, health and disease are all related to nature. For example, the six qi (wind, cold, heat, humidity, dryness and fire) are in the hot and humid dog days. Once the human body is deficient in vital qi and its resistance drops, it will become six evils, and summer heat will also become summer evil. " The summer weather is hot, the human body's yang floats on the body surface, and the skin pores expand. In addition, when the sun is the strongest in summer, it is more conducive to summer health. Therefore, there is a saying in Chinese medicine called' eat radish in winter and ginger in summer'. ""Ginger tastes pungent and warm, and has the functions of regulating stomach, strengthening spleen and protecting yang. In summer, the yang is floating, and the yang in the internal organs is weak. Eating more ginger can properly nourish yang. "In fact, the same is true of moxibustion therapy. Moxibustion ointment is generally treated with ephedra and ginger isothermal drugs through the corresponding acupoints of the human body. " Because the acupoints have two-way hot spots, and the acupoints are relatively unobstructed in summer, after the drugs are permeated and absorbed, warming the lung meridian and Yang Qi can melt the cold evil hidden in the body, adjust the balance of yin and yang in the human body, and achieve the purpose of' treating winter diseases in summer'. "Since you want to replenish Yang, of course, you should drink less cold drinks and herbal tea; Blow less air conditioning and pay attention to keep warm and keep out the cold. According to Professor Qin Min, cold drinks are harmful to the yang of viscera. Internally, don't drink too many cold drinks, herbal tea and eat too many watermelons.
