Hyperthermia
elevated body temperature due to failed thermoregulation that occurs when a body produces or absorbs more heat than it dissipates / From Wikipedia, the free encyclopedia
Hyperthermia is a high body temperature. It happens when a person is not able to control their body temperature. This can happen for many reasons, like very hot weather, fever, and some medicines or illegal drugs.
Doctors define hyperthermia as a body temperature that is over 101 degrees Fahrenheit (equal to 38.3 degrees Celsius).[1] This is higher than the normal healthy human body temperature, which is normally around 98.6 degrees Fahrenheit (37 degrees Celsius). When a person gets hyperthermia, they can have heat-related injuries, where the high body temperature hurts the body.
There are three forms of heat-related injuries caused by hyperthermia: heat cramps (the least serious), heat exhaustion, and heat stroke (the most serious).
The opposite of hyperthermia is hypothermia.
