With enough fans and keeping the humidity out, then it's not that hard to stay comfortable, well until you decide to cook but on hot days, I use only my microwave.

When I was a child mom used to wet our sheets down with a spray bottle so that we could fall asleep under them and it did work as long as we fell asleep fast.

I never heard of putting wet sheets in front of the windows but i can see where that would work.

I am staying cool with my air conditioning, even though I have the air conditioner set at 80 degrees.

I hope you're doing ok, I think I'ld probably wet a few bandanas down and put them in the freezer so I could change them out as they melt.
