But after several people do the same exercise, some people sweat more and some people sweat less, because the amount of sweating varies from person to person. First of all, sweat depends on the secretion of sweat glands, and the number of sweat glands is not only gender differences, but also individual differences; In addition, the amount of sweating depends on the body fluid content. Some people have more body fluids and sweat more when exercising; On the contrary, you sweat less when you exercise. The amount of body fluids is determined by the fat content in the body. Because there is less water in adipose tissue, 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, that is to say, if the exercise time is not long, fat people will be prematurely tired due to metabolic disorder.

Whether to drink water before exercise also has an effect on sweating. If you drink plenty of water before exercise, it will lead to an increase in body fluids and sweating. Furthermore, it depends on the physical quality of the individual. People with strong physique have relatively healthy muscles and motor organs. Even if they exercise harder, they naturally have no strength and sweat less. On the contrary, people with poor health will sweat a little.

So sweating more is not the better exercise effect. Some sweatless exercises, such as walking and cycling, can also prevent or reduce various chronic diseases, and also help reduce the risk of stroke, diabetes, dementia, fracture, breast cancer and colon cancer.

Zhao Jisheng added that whether the exercise effect is good or not should be judged according to the heart rate during exercise. The calculation method is: the maximum heart rate during exercise =220- age, that is, the maximum heart rate of a 50-year-old person during exercise should be 170 times. If it exceeds, it proves that the exercise is overloaded, and attention should be paid to reducing it. As for those who sweat like rain after a little exercise, they need to see a doctor as soon as possible.
