I moved to Alabama in 1978, and i'm still not used to the heat and humidity. Probably never will be.
I learned years ago that you have to hydrate constantly when it is hot outside. When i'm at Disney, or even cutting the grass outside, I wear a Camelbak and drink from it constantly. I've found that I can handle the heat much better by drinking constantly. I also drink plain old water. And, when you think you've drank enough water, you haven't. Keep drinking.
I also wear loose fitting light colored (khaki) garments. I stopped wearing dark shirts and pants outside years ago. They made me feel hotter.
