Fever is the name orthodoxically given to human body temperature which rises above normal when Nature attempt to burn up or incinerate waste matter in the body system. When there is no excessive waste matter and the body cells are promptly and properly nourished and hydrated daily, there is no need for fever. It has been found that by the use of enemas the fevered condition has been alleviated within an amazingly short time.
Only at higher temperature the red blood cells can "fight" better. Hope you see the point of fever. Battle is going inside your body when the fever is rising. Use water to help the soldiers inside to win the war for you. Simple.
