hyperthermia
Sign in to saveAlso known as overheating, heat stroke
Hyperthermia, also known as overheating, is a condition in which an individual's body temperature is elevated beyond normal due to failed thermoregulation. The person's body produces or absorbs more heat than it dissipates. According to the International Emergency Medicine Education Project, severe hyperthermia (body temperature elevation of beyond ) "becomes a medical emergency requiring immediate treatment to prevent disability or death". Almost half a million deaths are recorded every year from hyperthermia.

Hyperthermia, also known as overheating, is a condition in which an individual's body temperature is elevated beyond normal due to failed thermoregulation. The person's body produces or absorbs more heat than it dissipates. According to the International Emergency Medicine Education Project, severe hyperthermia (body temperature elevation of beyond ) "becomes a medical emergency requiring immediate treatment to prevent disability or death". Almost half a million deaths are recorded every year from hyperthermia.
The most common causes include heat stroke and adverse reactions to drugs. Heat stroke is an acute temperature elevation caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms of the body. The latter is a relatively rare side effect of many drugs, particularly those that affect the central nervous system. Malignant hyperthermia is a rare complication of some types of general anesthesia. Hyperthermia can also be caused by a traumatic brain injury.
