As someone who has gone through entire summers in New Orleans with minimal or no A/C, I can give you some advice:
Lots and lots of fluids. It really makes a difference. Make sure you get enough salt, too. 1 cup of gatorade for every 2 cups of water is good if you are really getting into a sweat.
Fans.
Being a person who doesn't like 200 and 300 dollar utility bills in the summer, I tend to not turn on the A/C until the house gets over 85. But I am sure I have 10 fans of different sizes and types going right now.
Light clothes, lots of fluids and moving air surely make the difference.
and if you have no air conditioning, hop in a cool bath every so often.
I appreciate the advice. 5 fans going now plus the a/c (which will allow me to sleep) in the bedroom. I'm thinking tomorrow might be a good day to clean the basement as it is the coolest place in the house. And yes, I know that N.O. residences don't have basements:) I am a salt addict ( not usually a good thing to be, but) and I drink everything in sight (well...you know what I mean)...Luigi's ice is good for bringing body temp down.
