Vacuum air conditioner filters weekly during periods of high use. Air conditioner filters can become clogged or filled with dirt, making them less efficient. Keeping them clean will allow your air conditioner to provide more cool air. If your home does not have air conditioning, go to a public building with air conditioning each day for several hours. Air conditioned locations are the safest places during extreme heat because electric fans do not cool the air.
Fans do help sweat evaporate, which gives a cooling effect.
Lightweight, light-colored clothing reflects heat and sunlight and helps maintain normal body temperature. Cover as much skin as possible to avoid sunburn and over-warming effects of sunlight on your body. Protect face and head by wearing a wide-brimmed hat. A hat will keep direct sunlight off your head and face. Sunlight can burn and warm the inner core of your body.
