In extreme heat and high humidity, evaporation is slowed and the body must work extra hard to maintain a normal temperature”.

Persons that are exposed to extreme heat can experience heat disorders. Conditions that can induce heat-related illnesses include stagnant atmospheric conditions and poor air quality. One of the most serious illnesses resulting from heat is a heat stroke. Heat stroke is described as a true medical emergency that can be fatal if not properly and promptly treated. Heat stroke will occur if the body is unable to diffuse the heat during excess humidity or extreme heat; the body temperature then begins to rise beyond normal levels. Severe dehydration is another cause of heat stroke. Common symptoms of heat stroke are Read the rest of this entry »
