Why do the doctors advise to put strips of wet cloth on the forehead of a person having high fever?

Answer:
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. Thus, moist strips will lower his body temperature.
