Heat rash looks like tiny bumps surrounded by a zone of red skin. It usually occurs on clothed parts of the body, such as the back, abdomen, neck, upper chest, groin or armpits and goes away on its own within a few days. In severe forms, however, heat rash can interfere with the body's heat-regulating mechanism .





Heat rash occurs most often in hot, humid conditions, but you may develop it in cool weather if you are overdressed. It's most common in infants.











Heat rash begins with excessive perspiration, usually in a hot, humid environment. The perspiration damages cells on the surface of the skin, forming a barrier and trapping sweat beneath the skin, where it builds up, causing the characteristic bumps. As the bumps burst and sweat is released, you may feel the prickly, or stinging, sensation that gives this condition its common name.|||You could be allergic to the sun. Sounds weird but there are people who are, typically it effects people with very light skin.|||I agree with blushlila...you could well be allergic


to the sun. Do you start feeling itchy and a burning


sensation the minute you step out in the sun?





If you are not allergic to the sun then try the other


suggestions-using baby powder, etc. You can also


try appling a deoderant in any creases on your body


where sweat accumulates.
