is humid heat or dry heat more dangerous?

708 views

With my extremely limited knowledge of thermodynamics, it seems like high humidity would provide enough water to transfer some of the summer heat.

Is it enough to make a difference?

Thanks so much for your responses! I had no idea that cooling came from the evaporation of sweat versus the just having water on you. I was going to reply to everyone, but the response seems to be the same across the board. I really appreciated everyone taking the time to educate little ole me 🙂

I once spent a few days above a wet-bulb temperature of 32C.

With 100% humidity and 32C your body is unable to shed heat and after a few hours of activity in this weather even healthy heat adapted athletes will begin to die.
