Tips For: Staying Safe in a Heat Event     Heat Related Illness


A Heat Wave is a prolonged period of excessive heat and humidity. The National Weather Service steps up its procedures to alert the public during these periods of excessive heat and humidity.

The Heat Index is a number in degrees Fahrenheit that explains how hot it really feels (much like wind chill for cold weather) when the relative humidity is added to the actual air temperature.

Heat Cramps are muscular pains and spasms due to heavy exertion. They usually involve the abdominal muscles or legs. It is generally thought that the loss of water from heavy sweating causes cramps.

Heat Exhaustion typically occurs when people exercise heavily or work in a warm humid place where body fluids are lost through heavy sweating. Blood flow to the skin increases, causing blood flow to decrease to the vital organs. This results in a form of mild shock. If not treated, the victim’s condition will worsen. Body temperature will continue to rise and the victim may suffer heat stroke.

Heat Stroke is life threatening. The victim’s temperature control system, which produces sweat to cool the body, stops working. The body temperature can rise so high that brain damage and death may result if the body isn’t cooled quickly.
