Fever is a natural response of the body that helps in fighting off foreign substances, such as microorganisms, toxins, etc. Body temperature is set by the thermoregulatory center, located in an area in the brain called hypothalamus. Body temperature is not constant all day, but actually is lowest at 6 A.M. and highest around 4-6 P.M.

It is also important to realize that certain normal conditions can effect body temperature, such as pregnancy, food ingestion, age, and certain hormonal changes.
