Hyperthermia means a body temperature above normal. Generally body temperature is around 98.6 ° F. Hyperthermia is not synonymous with fever because fever is considered a deviation from the midpoint of what is considered the normal body temperature while hyperthermia is an increase in temperature when the ability to compensate for the rise in temperature is compromised. Hyperthermia may well be due to too much or too long exposure to heat or too intense physical exertion: it is also referred to as heat stroke. Some drugs can also cause hyperthermia. The treatment is rest, gradual cooling, and adequate hydration. Antipyretics such as acetaminophen do not have any effect on hyperthermia.
