If the body cannot rid itself of the heat it is producing, or being exposed to, it will literally overheat. The body’s normal temperature is around 370C. Anything above a couple of degrees and things begin to shut down, including the brain and organs. Workers working outdoors in hot environments are the most susceptible. But heat emergencies can also occur to workers in hot indoor environments, such as, firefighters, construction workers, cooks, factory workers. Factors that might make it worse include; heavy clothing, humidity, medical conditions, certain medications, lack of acclamitazion, dehydration, age (yound and old are more susceptible), etc. There are three major levels of severity; heat cramps, heat exhaustion and heat stroke.
