Generally speaking, the amount of exercise determines your sweating, but some people have special physique and do a lot of exercise in time, but they still don't sweat. You should pay attention. Regarding sweating during exercise, we should pay attention to the following situations: it is easy to get heatstroke if you don't sweat during exercise, and you should be alert to rheumatism when you sweat heavily during exercise. Many people think that the more you sweat during exercise, the better the exercise effect. In fact, a lot of sweating will take away potassium ions, sodium ions, salts and other substances in the human body. For people with poor constitution, excessive sweating may lead to dehydration, dizziness, abdominal pain and other symptoms. In addition to poor physical fitness, you will sweat a lot when you are doing non-sweating exercises such as walking and playing Tai Ji Chuan. You should go to the hospital to check whether there is rheumatism. Don't take a bath immediately after sweating. At the end of exercise, the human body is still in a state of vigorous metabolism and vasodilation of the skin. At this time, if you take a bath immediately, the skin will be stimulated, and the skin blood vessels will contract through nerve reflex, but it will make it difficult to dissipate heat and raise the body temperature. Experts remind: the reduction of skin blood flow increases the blood flow back to the heart and increases the burden on the heart. Because sweat contains more sodium chloride, so sweat should be supplemented with salt and calcium. Therefore, after exercising in summer, you should drink some salt water properly, and then rest for about 1 hour before taking a bath. Of course, it is best to take a bath with warm water.
