Luckily, I live somewhere where it seldom gets really hot--and when it does it's only for a few days. We have two large box fans that we set at each end of the apartment, one sucks in the shady air, one blows out the window the hot interior air (we switch them around as the sun moves across the sky). We also have smaller tabletop fans we can aim directly at someone sitting and I usually have one going in the bedroom since the bedrooms gets really hot. I get up early in the morning and open the windows to let in the cool dawn air, then pull the shades/curtains so the sun can't heat up the inside. If I get really hot myself, I run cool (not cold) water over my feet, wrists, inner elbows and neck, sometimes I run cool water over my head and I usually can cool down that way--a warm-cool shower also works for a while but we often are in drought conditions so I don't want to use too much water. I strip down as much as possible (just wear a woven cotton long shirt to cover my risky parts). We always keep water cooling in the frig and I drink a lot of it, sometimes I'll do iced coffee (since I don't particularly like tea). I try not to do too much and if I need to go somewhere, I stick to the shady sides of the street and try to do my outdoor chores either really early in the morning (before the sun gets going) or after the sun sets if it's cooled off enough. I even put ice in our pets' water bucket so they can have cool water (and I change it more frequently). I've also been known to wear my Ray-bans indoors since seeing the world in that dark green/grey shade seems to help me convince my mind it isn't as blaring hot as it really is. I eat things that don't need to be cooked--eat a lot of salads since I usually don't want anything heavy. Sleeping is usually hard since the mattress always seems too hot and I lie there wishing I had a hammock. I don't know why but the cats always want to snuggle their hot furry bodies right up against me (ugh) and I hate yelling at them to get away from me but, hey, I'm hot. I also wish I had a transom over my doors so I could open them and let any cross-breeze waft through without the cats getting (but transoms must have been deemed a fire hazard or something). Oh, and I have been known to go to supermarkets and spend literally hours shopping and not buying much just so I can be in their A/C. Same with movies. And anywhere else I can find that has A/C since I don't have it at home (nor do I want it at home).
