The trapped sweat leads to irritation, itching and to a rash of very small blisters, usually in a localized area of the
skin. These
rashes may occur in the face, neck,
skin folds, areas of the body that may rub against clothing, such as the back, chest, and stomach.This can be prevented by avoiding activities that induce sweating, using air conditioning to cool the environment, wearing light clothing and in general, avoiding hot and humid weather and taking frequent cool showers .
