Geeeze, Take off your shirt??? Holy hell, there's this thing called melanoma man. I may be a wimp, but if I can't apply sunscreen to it, it's covered. Of course, I could be over reacting because skin cancer runs in my family, and seeing the holes that are left behind is a sobering testament for sun protection. However, I do like to see other people in various stages of undress, so if you can, ride as nude as you feel. I'll be the dude who's so pale you can't look directly at him in sun light.

For me:
Pick optimum riding times
No Overexertion in +95 F
Hydration
Cool off period

TA-DAA! no heat stroke yet!
