Question

why do doctor generally advise to put strips of wet cloth on the high fever

Answer 1

so that the temparature donot rise

Answer 2

When a person has fever his body temperature becomes more than the normal body temperature. If we put strips of wet cloth on the forehead of a person suffering from high fever, the water evaporates taking heat from the body, creating a cooling effect. Thus, moist strips will lower his body temperature.
