Sweater pants are very common in life, because they can effectively cool down and sweat, so many people will buy some at home, but they can't sleep directly in them. If you want to take them out and put them on the bed, no problem, but keep warm, and it is best not to sleep naked. Sweating pants are made of polyester. After high-temperature evaporation, polyester will absorb a lot of water and heat, causing local muscle aches and making people feel cold. Moreover, wearing sweaty pants for a long time will cause diseases such as inguinal and pelvic floor varicose veins, which will affect your health.
