I think the hottest I've ever been in my life was when I lived in Boston back in 1968, the third floor apartment on Beacon Hill.

I would pull out the sofa bed, point the fan at the mattress, turn off all the lights except in the bathroom, and get in the shower, with the water turned down as cool as I could stand it.

Then I'd turn off the shower, flip off the bathroom light and leap onto the mattress soaking wet, hoping to fall asleep before I evaporated.
