Hyperthermia is a fast onset state that happens when the body can't rid itself of heat speedily enough. It occurs when the environment outside the body is not conducive to the body shedding heat quickly enough. This is recognized as the thermal gradient.

If the body gets warm enough, its internal apparatus to control temperature goes out of order. The inner thermostat of your body gets set to the uppermost setting. Your body will continue to heat up to the point that you may possibly die.

Body temperatures above 40 degrees celcius (104 degrees fahrenheit) are life-threatening. This compares to regular human body temperature of 36-37 degrees celcius (97-98 degrees fahrenheit). The usual skin temperature away from the center is about (90 degrees fahrenheit) At 41 degrees celcius (106 degrees fahrenheit), brain death begins, and at 45 celcius (113 degrees fahrenheit) death is nearly certain. Internal temperatures above 50 degrees celcius (122 degrees fahrenheit) will cause rigidity in the muscles and certain, immediate death.

The body becomes overheated. The body loses its ability to control temperature. If this is not controlled quickly, brain damage may result.

A person does not have to be in a very hot environment for hyperthermia to occur. Certain drugs hinder the capacity of the body to regulate temperature. Other medicines interfere with the ability of the body to perspire. The youthful and mature are at more risk. Some conditions will also alter the ability of the body to shed heat.
