Can a 38-degree old man move?

You can't. Old people can't exercise in hot weather. Because the organ function of the elderly declines, the water in the body is less than that of the young people 15%, and the heat resistance is far less than that of the young people. The elderly have a high probability of heatstroke in hot days. The weather is 38 degrees, which belongs to high temperature weather. Meteorology in China, when the temperature is above 35 degrees Celsius, it can be called "high temperature weather", and if the highest temperature exceeds 35 degrees Celsius for several days, it can be called "high temperature heat wave".
