I deal with heat and humidity, and one of the things I've started doing after noticing the MLB guys do it is putting some towels in a cooler filled with ice water, and just covering your head with one between innings. Sure, you get a little wet, but it's worth it.

I also wear underarmour-they make a looser shirt that I like-unquestionably, the best "cool shirt" on the market.
