Quizplus · Accepted Answer

A fever is not generally caused by an inability of the body to get rid of excess heat, as in heat stroke. It is typically caused by an immune response to an infection or inflammation, which leads to an upward resetting of the hypothalamus and an increase in body temperature. While a fever can be reduced by aspirin, it is not necessarily the case that it will always respond to antipyretic medication. A fever is "broken" when the hypothalamus resets back to its normal temperature range, which can be achieved through mechanisms such as vasodilation and sweating.
