Wipe the atmosphere as a fever, you should use the "warm" or "cold".         
           When the temperature is hot, many people will not get a fever-reducing drug consumption. But if you feel tired and very hot. Even after treatment. Symptoms that may be not much better. I need help with a damp cloth to compress the normal temperature on the forehead. Then sleep. 

          When you wake up. Found to have fever. The fever can be wiped out. But some people just use cold water. Sometimes the ice is mixed with water. While some people use hot water. In fact, it's cold or warm water using sponge and helps reduce fever. 


         Why not use cold water to sponge. The cold water will make people feel chills, fever, more than ever before. This cooling of the water. The muscle and blood vessels under the skin contraction. The increasing power consumption. The body heat up again.     Reduce the body temperature down significantly. 

           However, a fever, and medication to reduce fever. Herbal damp cloth on the forehead. Then wipe with warm water. It should drink as much water at room temperature. It helps, too.

    
         The answer of this question is 'water' as a warm damp cloth to wipe the sweat off the body will allow. It is toxic to the body heat of the fever out.
