A heat rash is a medical condition in which the sweat ducts in the skin are blocked, so the sweat that forms in the sweat glands of the skin cannot get to the skin surface to evaporate. Instead, sweat remains trapped below the skin surface, causing an inflammation and a skin rash. A heat rash is also called a prickly heat and miliaria. Various factors can contribute to the heat rash, such as tight clothing that prevents sweat from evaporating, heavy creams or lotions that clog pores, intense exercise and dressing too warmly.
