I understand your feelings about the heat and humidity (and I live in the DC area so it can get really bad here). But if you have a ceiling light fixture in your bedroom you might want to install a ceiling fan (like in the movie Casablanca). It doesn't generate the kind of coolness a regular fan does (so you won't get the muscle cramps), but it will circulate the air around the room making it more livable and the girls could come back in...
