Stating the obvious -sweat is precious water being used to cool down your body. Allowing it to escape in high heat conditions where replacement water may be scarce is very unwise. Keeping hydrated at all times is critical.
Want to feel great as you are baking? as you refuel, find a hosepipe/tap/water can and drench your jacket, trousers and helmet and keep those vents closed.

This is counterintuitive, but all true, or so the experts tell us. You really want to keep the "sweat inside". Too much air flow can really dehydrate you fast! We still see the Harley guys riding in a tank top and beany helmet in severe heat waves. Then at the next Tavern stop, they pass out. Been there, seen this in person. So cover up, keep some of the sweat inside. Booze makes it all worse.
It's a delicate balance between comfort and safety. Some air flow/venting is good but TOO MUCH is NOT good. And of course, as stated : Drink Drink Drink!
In the tropics, riding small roads at low speed, a mesh jacket works well, but it's always hard to stay comfortable with high humidity with high temps.
I've used the wet T shirt/helmet technique for decades. Great in Desert, not so much in tropics.
