Heat rash or miliaria is a common form of skin rash. This type of rash affects children and adults in warm, humid weather conditions. A rash might develop if the pores are blocked and sweat could not escape.

The cause is often friction on the skin surface. Among adults, heat rash develops on parts of the body that rub together such as under the arms or between the inner thighs. Infants often develop the rash on the neck area but also in the skin folds especially in the elbows, armpits and thighs.
