Re the sweating and standing in front of a fat. My suggestion is to keep drinking and perhaps find some place air conditioned to hide out.

Your body's defence against overheating is to sweat, by standing in front of the fat you may 'feel' cooler, but you're evaporating the sweat and actually making yourself warmer and more dehydrated.

A cool/cold shower or bath might help - before we got AC here it was what I'd do when it got unbearable.
