You should not sweat when your child has a fever. First of all, sweating will raise the child’s body temperature, which is not conducive to reducing the fever. In addition, sweating can make your child sweat a lot, which can easily lead to dehydration, which is bad for fever. Sweatshops can easily breed cryptococcus, a fungus that tends to thrive in dark, humid places with poor air circulation, and saunas and sweatshops are one of them. When children have a fever, their resistance is greatly reduced, and pathogenic bacteria like cryptococcus are especially likely to enter their bodies through the respiratory tract, thus causing pneumonia. What’s more, the alternating hot and cold during the steam will instead weaken your child’s resistance to viruses, so the best thing to do when your child has a fever is to need more rest.
