In order to adapt to the hot environment outside, the body’s thermoregulatory center increases heat dissipation through various means to maintain a constant body temperature, the most effective means is to absorb metabolic heat through sweat evaporation. The outdoor temperature often exceeds 30 degrees Celsius, plus the relative humidity in the air is relatively high, the body to the outside heat dissipation is hindered to a certain extent, at this time, the evaporation of sweat to take away the heat in maintaining the body temperature constant role is particularly prominent. But this also brings a great deal of hidden danger to the body. In addition, sweat is the heart fluid, sweating is the heart qi damage, will appear palpitations, weakness and other symptoms of heart qi deficiency; In addition, sweating is Yang qi injury, Yang qi main guard outside, solid table, Yang qi injury is not solid outside the guard, will lead to spontaneous sweating, night sweating. In healthy people, due to the balance of yin and yang, even if the Yang Qi is slightly damaged in summer sweating, the balance of their own yin and yang will soon be balanced again, and there will be no spontaneous sweating, night sweating, or the development of palpitations and other symptoms. Sub-healthy and sick people are already on the verge of imbalance due to their own Yin and Yang balance, plus the hot weather in summer and autumn causes excessive loss of sweat and damage to Yang and Yin qi, thus easily triggering spontaneous sweating and night sweating, so these people should pay more attention to the discomfort brought by the climate. Therefore, sub-healthy people and disease people in the summer and autumn season should pay special attention to the solid protection of the body, avoid doing a lot of exercise in hot weather, so as not to sweat a lot of Yang; in addition, should also avoid greedy cold drinking cold, pay attention not to blow straight air conditioning, so as not to wind cold injury Yang, spontaneous sweating and cold and other diseases.
