Usually, the greater the intensity of exercise, the more you sweat. Because with the increase of exercise intensity, muscle activity is more intense and more calories are produced. In order to maintain a normal body temperature, the human body must increase the amount of perspiration to emit excess heat. Therefore, the greater the intensity of exercise, the more perspiration is bound to occur. ?
In addition, individual differences are also reflected in the number of body fluids. Some people have more body fluids and sweat more when exercising; Some people have less body fluids and sweat less when exercising. The amount of body fluids often depends on the fat content in the body, because there is less water in adipose tissue, so fat people have less body fluids than thin people. Although fat people sweat a lot during exercise, their tolerance to water loss is relatively poor, which means that if the exercise time is not long, fat people will be prematurely tired because of water and salt metabolism disorder.
