Sweating over a cold and fever is a relatively unscientific method of treatment, because there are many types of colds, including wind-cold, wind-heat and summer-damp colds.

However, wind-heat cold is caused by heat entering the body, and summer humidity cold is caused by hot and humid weather, and it is difficult to expel moisture from the body. At this time, if the excessive warmth, serious sweating, but not conducive to heat and moisture dissipation, more likely to aggravate the performance of fever, so the current clinical advice for patients with a cold and fever to cover the sweat this way to reduce fever treatment. Generally speaking, it is still necessary to use anti-cold drugs or fever-reducing drugs for treatment.
