Thermal Therapy is a fast onset disorder that happens when the body cannot get rid of its heat firm enough. It happens when the atmosphere outside the body is not favorable to the body peeling heat quickly enough. This is known as the thermal gradient.
If the body gets hot enough, its internal mechanism to regulator temperature goes out of order. The internal thermostat of your body gets set to the highest setting. Your body will continue to heat up to the point that you may possibly expire.
Body temperatures above 40 degrees Celsius (104 degrees Fahrenheit) are dangerous. This links to normal human body temperature of 36-37 degrees Celsius (97-98 degrees Fahrenheit). The normal skin temperature away from the central is about (90 degrees Fahrenheit) At 41 degrees Celsius (106 degrees Fahrenheit), brain death begins, and at 45 Celsius (113 degrees Fahrenheit) death is nearly sure. Internal temperatures above 50 degrees Celsius (122 degrees Fahrenheit) will cause rigidity in the muscles and certain, instant death/expiry.
Hyperthermia has 3 distinctive stages:
Stage 1 is called Heat Cramps. This stage is considered by muscle spasms or twinges. They generally start in the large muscles. Heat cramps are caused by inequity in the electrolytes of the body.
Stage 2 is called heat exhaustion. This stage is categorized by a mild state of blow. They body has increased the size of the blood vessels in an attempt to get rid of its extra heat. The body is also sweating abundantly at this stage, which can cause a state of dehydration. The skin color will be light. The temperature will be normal to elevated. Note that at this stage people still exudate. The heat compensation mechanisms of the body are running at 100% at this point. A person may also be faint or pale.
Stage 3 is called heat stroke. This has a death rate of 20-80%! The heat recompense mechanisms of the body have become overcome and are shutting down. The body becomes inflamed. The body loses its ability to control temperature. If this is not controlled quickly, brain damage may result.
