Heat stroke occurs when the body cannot adequately dissipate heat through evaporation of sweat or radiation of heat from the skin, typically caused by extreme heat, high humidity, vigorous exertion under the sun, or dehydration. Heat exhaustion, a milder form of hyperthermia, may occur initially and progress to heat stroke if not properly treated.

Absence of sweating
Hot, red, flushed skin
Because heat stroke can cause permanent organ damage and even death, immediate treatment is imperative. If you suspect a child or adult is experiencing heat stroke, quickly call 911 then take measures to cool the victim. Move victim out of the sun, remove clothing, fan the victim, lightly spray with cool water, and place ice packs under the arm pits. The 911 operator can assist you with further instructions as emergency personnel are in route.
To avoid heat exhaustion or heat stroke, limit outdoor activities when the temperature and humidity are high. Opt to play or exercise outdoors before 10am or in the early evening, when the temperature is cooler. Another key preventative factor is to stay hydrated. Drink at least 8 (8-ounce) glasses of water daily and keep your intake of caffeine and alcohol to a minimum.
