Fever

Fever is one of the most common medical signs and is characterized by an elevation of body temperature above the normal range of 36.5–37.5 °C due to an increase in the temperature regulatory set-point. This increase in set-point triggers increased muscle tone and chills. As a person's temperature increases, there is, in general, a feeling of cold despite an increasing body temperature. Once the new temperature is reached, there is a feeling of warmth. A fever can be caused by many different conditions ranging from benign to potentially serious. Some studies suggest that fever is useful as a defense mechanism as the body's immune response can be strengthened at higher temperatures, however there are arguments for and against the usefulness of fever, and the issue is controversial. With the exception of very high temperatures, treatment to reduce fever is often not necessary; however, antipyretic medications can be effective at lowering the temperature, which may improve the affected person's comfort. Fever differs from uncontrolled hyperthermia, in that hyperthermia is an increase in body temperature over the body's thermoregulatory set-point, due to excessive heat production and/or insufficient thermoregulation.
