extreme heat


Extreme Heat often results in the highest number of annual deaths among all weather-related hazards. In most of the United States, extreme heat is defined as a long period (2 to 3 days) of high heat and humidity with temperatures above 90 degrees. In extreme heat, evaporation is slowed and the body must work extra hard to maintain a normal temperature. This can lead to death by overworking the human body. Remember that:

 IF YOU ARE UNDER AN EXTREME HEAT WARNING:


During extremely hot and humid weather, your body's ability to cool itself is challenged. When the body heats too rapidly to cool itself properly, or when too much fluid or salt is lost through dehydration or sweating, body temperatures rise and you or someone you care about may experience a heat-related illness. It is important to know the symptoms of extreme heat exposure and the appropriate responses 

Heat Stroke

Using a fan to blow air in someone’s direction may actually make them hotter if heat index temperatures are above the 90s.

Heat Cramps


Heat cramps may be the first sign of heat-related illness, and may lead to heat exhaustion or stroke.

Heat Exhaustion

Each year, dozens of children and untold numbers of pets left in parked vehicles die from hyperthermia, which occurs when the body absorbs more heat than it can handle. Hyperthermia can occur even on a mild day with temperatures in the 70s. Studies have shown that the temperature inside a parked vehicle can rapidly rise to a dangerous level for children, pets and even adults. Leaving the windows slightly open does not significantly decrease the heating rate. The younger the child the more severe the effects because their bodies have not developed the ability to efficiently regulate its internal temperature.
