What is sweat rash?

Sweat rash is a red, itchy rash on the skin. Anyone can get sweat rash. Not surprisingly, the rash is linked to sweating! Therefore, people who sweat more have an increased chance of getting sweat rash. Such people include those who play a lot of sport and those who are overweight. It usually happens where chafing occurs or when sweat gets trapped between two layers of touching skin or between skin and clothes.

Areas that are usually affected include the armpits, under breasts, around the groin and between the legs and the arms. Along with the redness and irritation of the chafing, the rash may also become infected, increasing the problem.
