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.
Get trained in first aid to learn how to treat heat-related emergencies.
