Window awnings can do more than add charm: They reduce warming from the sun by 77 percent. Not ready to make the investment? Lower the blinds or close the curtains to block half of that heat.
A cold bath or shower can lower your body temperature. Or, place a chilly washcloth on your wrist or neck. That's where blood vessels are closest to the skin, so you'll cool down faster.
Hot air rises, so spending less time on the top floor of the house might keep you out of harm's way.
Electronics like televisions, lamps, and computers can raise a room's temperature. Put them to sleep or turn them off when they aren't in use.
If you have air-conditioning units (window or central), clean the filters once a month and coils twice a year. Dirt can block airflow, reducing chill factor and bumping up your energy bill by up to 15 percent.
