About Heat Exhaustion

Heat illness or heat-related illness is a spectrum of disorders due to environmental heat exposure. It includes minor conditions such as heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke. Heat stroke is defined as a body temperature of greater than 40.6 C (105.1 F) due to environmental heat exposure with lack of thermoregulation. This is distinct from a fever, where there is a physiological increase in the temperature set point of the body. Treatment involves rapid mechanical cooling. A number of heat illnesses exist including: Heat stroke presents with a hyperthermia of greater than 40.6 C (105.1 F) in combination with confusion and a lack of sweating. Substances that inhibit cooling and cause dehydration such as alcohol, caffeine, stimulants, medications, and age-related physiological changes predispose to so-called classic heat stroke. Exertional heat stroke can happen in young people without health problems or medications, most often in athletes and military recruits. Children, elderly adults, or disabled individuals left alone in a vehicle are at particular risk of succumbing to heat stroke, even with windows
