I am a 17-year-old girl. Usually he sweats when he moves, and physical education class's clothes are all wet. I feel particularly embarrassed. What is the reason?

Are you particularly fat? If you are obese, you will sweat a lot if you exercise too much. If you are not particularly fat, it means that you are weak and may be sweating. In this case, you'd better go to the hospital for a comprehensive examination to see what causes you to sweat. It should be in a sub-health state now, and find out the cause as soon as possible.
