Great tips. I haven't use AC in my home for 2 years (freon leaked out & I'm too cheap to refill) but one gets used to the high temps and adjusts. There are days that seem fine to me while my co-workers can't imagine living w/o their AC - it helps knowing my ancestors lived w/o it for thousands of years.

 I have a dual fan where you can do one intake and one exaust. That, ceiling fans and an occasional cold shower work great.
