Because obese people have high fat content and poor thermal conductivity, the heat generated by metabolism in obese people is not easy to dissipate, and heat accumulation will lead to body temperature imbalance, and sweating is the most efficient way to dissipate heat. Therefore, fat people sweat more, and its physiological significance lies in dispelling excess heat in the body as soon as possible.

However, not all people in love sweating are fat. The amount of sweat is first related to individual differences: sweat comes from the secretion of sweat glands, and its amount is not only gender differences, but also individual differences. In addition, individual differences are also reflected in the number of body fluids. Whether to drink water before exercise also affects body fluids. If you drink plenty of water before exercise, you will also increase sweating due to the increase of body fluids.

Active sweating is the sweat produced by human body's active exercise to keep the body temperature and emit heat, so it is beneficial to physical and mental health. But it doesn't mean that the more you sweat, the better the exercise effect will be. Generally speaking, the greater the intensity of exercise, the more you sweat. But the process of sweating is mainly to dissipate heat and cool down. Sweating a lot will lose water and salt in the body, leading to dehydration, and you can only lose weight temporarily, but you can't lose weight. People who sweat like rain after a little exercise need to go to the hospital for examination.

In addition, if you drink plenty of water before exercise, it will also lead to increased body fluids and increased sweating. It should be noted that drinking water should not be excessive during exercise. Drinking plenty of water will lead to sweating, further loss of salt and convulsions. In addition to hydrating, we should also pay attention to supplementing the necessary potassium and eat more foods rich in potassium, mainly beans, vegetables and fruits.

Hot weather makes people's demand for vitamins rise, so we should pay attention to supplementing foods rich in vitamin C and vitamin B at ordinary times. Generally speaking, when the body sweats a lot or the body temperature is too high, it is best to replenish water several times in a small amount, which can slow down the body's perspiration and reduce the evaporation of water in the body, while sodium supplementation depends on the amount of sweating.
