Heat rash

I think the arm coolers would probably work better in a drier climate. They get waterlogged pretty quickly in humidity, the way I sweat. At that point they don't help cool me, but they definitely are no hotter than bare skin. I have tried taking them off when it was unbearably hot, and it did not help. When they're not waterlogged, it's uncanny how much cooler they feel.

I get it too, but I typically get it under my shorts on the tops of my thighs. It looks just just like yours. It doesn't hurt, does not itch. And it goes away in a day or so. Since I put sun block on my whole legs, and only get the rash in the area covered by my bike shorts, I'm thinking that it is just a simple heat rash and that nothing really needs to be done. But if anyone has found a way to prevent it, or to make it go away faster, I'd love to hear.

I recently started developing the same thing. Since the first time it showed up was with a new pair of shorts, I thought I might be developing an allergy to the silicone in the gripperbands or something like that. Took a baby benedryl, rinsed it off with cool water and put aloe vera on it and it was cleared up by the next day. Since I got it again with an old familiar pair of shorts yesterday, I guess it is heat rash and will start putting on an allergy cream before I put on the shorts- good to know what it is.

Have you recently started taking any new medication? Sometimes medicine will make you hypersensitive to the sun and rashes even if you normally aren't prone to that.
