is humid heat or dry heat more dangerous?

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 🙂

High humidity prevents you from cooling due to your sweat evaporating, so high humidity is much more dangerous. For instance at 100% humidity, your sweat wouldn’t evaporate at all.
