Some simple ideas to help keep cool:
Drink as much cold water as you can. Eat smaller meals and more often. The larger and hotter the meal, the more metabolic heat your body creates breaking down the food. Avoid foods that are high in protein e.g. meats, which increase metabolic heat. Ironically spicy food that causes sweating can help to cool you down; the bathroom is generally one of the coolest rooms in the house, so frequently required visits if you make it too hot, also help keep you cool.
Close the curtains or blinds on the sunrise and sunset sides of the house respectively – open once the sun has gone. A desktop or portable fan only uses around 40Wh so running for 24 hours will cost you around R1.60; make sure all fans blow counter clockwise in summer; specially ceiling fans. Point fans out the windows so they push hot air out. Fans with built in misters are also available; they use around 75w with the mister running. They typically use around 1 litre of water per hour.
Keep windows and doors open to let the breezes blow through. You can cool down a whole room by hanging a wet sheet in front of an open window; breezes blowing in will quickly bring down the room’s temperature. Try to keep one room cool if you can't afford to cool the whole house; make this a south facing windowed room. Consider tinting a few windows on the east, north and west side of the house. If you can afford ceiling insulation do it yesterday; this also helps to keep the winter chill out.
