How to keep fit in hot weather?

In summer, the temperature is often 37? Between 39 degrees, sometimes as high as 40 degrees, far beyond the normal heat-resistant range of human body, people live in such a high temperature season, and only when they get used to it can they spend it safely. Summer heat is called yang evil in Chinese medicine. Yang pathogen is easy to damage yin, which causes disease, with rapid onset and short course of disease. Most of them have strong fever, red face and red eyes, thirst and upset, and even mania, delirium and coma. The internal heat of the body is excreted through sweating, and the temperature is 28? At 30℃, the heat in the human body can leak out smoothly. If the outside temperature exceeds 34 degrees, sweating is blocked, and a large amount of internal heat accumulates in the body, it is easy to get heatstroke. Only when you are strong can you adapt to this high temperature and dissipate internal heat, so that you will not be affected by external heat.
