There are a number of things you can do, but not all of them are desirable to everyone.
Acclimate to the high temp/humidity by spending more and more time outside so your body adjusts. This takes about 3 weeks to be fully effective, but you can see a change in as little as 3 days.
Adjust your shooting schedule to the early cool part of the day. The lower the temp the less you have to adapt to.
Shoot in the shade. If you have to bring your own, do it.
Use cooling clothing instead of your standard heavy jeans and shirts.
Use cooling bandannas and "towels" really work at keeping you cool. Keeping a cooler with chilled water to wet these cooling garments is another way to fight the heat.
While we want to not take anything by mouth if we could transfer lead to ourselves we can bring a sealed cooler of chilled drinks and use wipes on hands and face before drinking the chilled water. Keep the core cool and you can keep the rest of your comfortable.
If you're very sensitive to heat invest in one of the phase change vests that you can wear and will keep your core cooled. They're now popular with motorcyclists to wear under leathers.
