Sweating is stronger than not sweating when you have a fever. Sweating has the effect of heat dissipation, which helps to lower the body temperature. It is necessary to drink more water, pay attention to rest, take vitamin C supplements, prevent cross-infection, and be alert to dehydration and convulsions caused by high fever. The fever should be treated with a light diet, with less spicy, stimulating and oily foods and sweets to avoid fire and phlegm, which can cause coughing and aggravate the disease. If the fever is caused by a viral infection, antiviral drugs such as ribavirin can be given as symptomatic treatment. If the fever is caused by bacterial infection, symptomatic treatment with antibiotic drugs, such as penicillins, cephalosporins, macrolides and quinolones, can be given. If the body temperature exceeds 38.5℃, you can use indomethacin suppositories in the anus or take antipyretic and analgesic drugs such as ibuprofen and acetaminophen orally, which can play a fast role in reducing fever.
