In most cases of colds with fever, you can drink brown sugar water appropriately. The main reason for having fever is that the immunity of the body is reduced and the body is infected by viruses and bacteria, causing an inflammatory response in the body and a continuous increase in body temperature. When the fever is low, for example, the body temperature is below 38.5 ℃, you can drink brown sugar water, which facilitates sweating and can promote urination to lower the body temperature through heat dissipation. When the body temperature exceeds 38.5℃ or more, you should not only drink brown sugar water, but also choose antipyretic drugs, such as ibuprofen, acetaminophen, diclofenac sodium, etc., while drinking a little brown sugar water to promote sweating and body temperature drop.
