But ... I find I'm doing things to cool off, things that I'll share with you.
I'll assume you already have a fan or two to help circulate the air.
Try taking lots of quick showers (coldish ones) if you're feeling overheated. Do it with a tshirt and your undies on to make the feeling last longer.
If at night you find you can't sleep, stand in the shower WITH A SHEET WRAPPED AROUND YOU and go back to bed with the wet sheet. The evaporation will keep you cool. I did this three or four times a night in Phoenix the week it got up to 122 degrees and the AC in my rental house died. And it got COMPLETELY DRY in between shower visits.
Other options ... hang out some place with AC (the movies are good, the one that came out about surfing might help even more). For some reason I think drinks with mint are extra cooling - mint italian sodas come to mind.
Finally ... try going to Lake Washington today (Denny Blaine beach) and resting in the shade, sporadically taking a dip in the water. Bring food, drinks, and a good book. You'll remember this as one of the most pleasant days of the summer if you do.
