Kind of a hijack ... but was it a dermatologist that told you that? When the humidity is high (including any time I wear gloves in warm weather) I get dyshidrosis on my hands (and to a lesser extent on my feet and forehead), which is a form of eczema. It got its name because they used to think it was a sweat disorder, but it turns out it really isn't. Ambient humidity alone can trigger it. I especially get it at the change of seasons, and then adapt a bit to the humidity. There's often a stress component too, like most auto-immune issues.

The heat rash I get is nothing like that, though. Two different animals.
