In Florida, our AC units pretty much run constantly. I turn mine up to 78-80 and run fans in each room. It stays fairly cool. I also have to use a cool, damp washcloth to help end the hot flashes. Really cools me off right away.

We never use the oven during the summer. Only microwave and cold stuff. Alot of people here turn their AC way up and go somewhere cool for the day. i.e. window shopping at the mall, grocery store. movie theater. Wherever there is AC and it doesn't cost a fortune. We drink cold drinks all the time. Alot of ice water or iced tea.
Basically, most of us sweat alot too I think. What else can we do? We're also fortunate to have swimming pools all over the place to cool ourselves off. Anything we can think of to make it through the summer down here.
