Fever is the body's natural response to a variety of conditions, such as infection. If the fever is mild and no other problems are present, no medical treatment is required. Drink fluids and rest.
Evaporation cools the skin and thereby reduces body temperature.
In addition to sponging with tepid water, place ice packs in the armpits, behind the neck and in the groin. Begin administering fluids if victim is alert. Seek medical attention. Don't bundle up in blankets if the person shivers or becomes chilled. This will only cause a fever to rise.
