My son reacts anywhere from instantly to within minutes of exposure to his contact allergens.

I am glad to have found this article. This has been an issue with my son for years. He doesn’t get the same symptoms, but he has eczema, so all that happens for him is that his eczema flares up. We had finally come to the conclusion that it was heat that was doing it, but we were hesitant about it because we’d never heard of any such thing, so it’s nice to know we aren’t crazy. We did think it was his sweat, and that was mentioned in the article, too, so I’m still not sure exactly what is going on. I don’t _think_ he usually goes around with stuff all over his skin that only causes him to break out when he sweats, but he doesn’t get rashy if he’s just too warm–it doesn’t happen till he sweats, usually copiously.

Hmmm…now I think about it, he doesn’t have a problem with hot baths or hot tubs, so maybe it is the sweat/contact dermitis thing. That’s distressing, because it happens often. I don’t know of a more gentle laundry detergent than All Free and Clear, and I don’t know what else would be bothering him.
