Whats a good way to stop or prevent heat rash?

try body powder w/ cornstarch.

Yes I am Canadian. Born and raised.

The best method is dusting powder, keeps the area dry, ointments aren't any good because they just keep the area hot and moist, which is what causes the heat rash

maybe if your husband had a brain and was smart enough to prevent this on his own this would not happen. or maybe you have some sort of disease that gives him this and you think its heat rash...hows this for playing with your head

powder is good also i'm not sure if it would work on a man but AVON cellusculpt when u put it on ur thight the skin jus gets silky so no chafing and also i can't remember but one of the feminine line like monistat or something has lotion specifically for chafing. just look around hat section in the store or the lotion section .

Chafing? I would make sure it wasnt jockitch..if it is, just use some lotrimin or whatever spray they are selling these days..regular heat rash/chafing use powder before dressing. It is caused from sweating and clothes or legs rubbing against the skin.

When I was in my 20's I had heat rash on my chest. It looked like little red pimples almost like measles. I powered my chest with cornstarch, the stuff you cook with, and it made them go away and prevented more from forming.
