3. Eat Cold Meals
Just as drinking a nice cold cocktail cools your body, eating cold food helps keep your internal temperature lower on a hot day. Try a simple watermelon salad, for instance, or a cold soup. If you do cook, use the grill or the microwave, or else you'll heat up your kitchen from using the oven and stove. And remember, kitchen appliances aren't the only devices that give off heat; limiting your use of electronics and lighting will help keep your home cooler, too.
