Extreme Heat

Heat kills by pushing the human body beyond its limits. In extreme heat and high humidity, evaporation is slowed and the body must work extra hard to maintain a normal temperature.

Most heat disorders occur because the victim has been overexposed to heat or has over-exercised for his or her age and physical condition. Older adults, young children and those who are sick or overweight are more likely to succumb to extreme heat.

Conditions that can induce heat-related illnesses include stagnant atmospheric conditions and poor air quality. Consequently, people living in urban areas may be at greater risk from the effects of a prolonged heat wave than those living in rural areas. Also, asphalt and concrete store heat longer and gradually release heat at night, which can produce higher nighttime temperatures known as the "urban heat island effect."

A heat wave is an extended period of extreme heat, and is often accompanied by high humidity. These conditions can be dangerous and even life-threatening for humans who don't take the proper precautions.

 

Before Extreme Heat

To prepare for extreme heat, you should:

·         To begin preparing, you should build an emergency kit and make a family communications plan.

·         Install window air conditioners snugly; insulate if necessary.

·         Check air-conditioning ducts for proper insulation.

·         Install temporary window reflectors (for use between windows and drapes), such as aluminum foil-covered cardboard, to reflect heat back outside.

·         Weather-strip doors and sills to keep cool air in.

·         Cover windows that receive morning or afternoon sun with drapes, shades, awnings, or louvers. (Outdoor awnings or louvers can reduce the heat that enters a home by up to 80 percent.)

·         Keep storm windows up all year.

·         Listen to local weather forecasts and stay aware of upcoming temperature changes.

·         Know those in your neighborhood who are elderly, young, sick or overweight. They are more likely to become victims of excessive heat and may need help.

·         Be aware that people living in urban areas may be at greater risk from the effects of a prolonged heat wave than are people living in rural areas.
