Heat Rash



Heat Rash Causes


Heat rash begins with excessive perspiration, usually in a hot, humid environment. The perspiration damaged cells at the outer part of the skin, forming a barrier and trapping sweat beneath the skin, where it builds up, causing the characteristic bumps.


Heat Rash Definition


Heat rash also called prickly heat or miliaria is a common condition in which areas of the skin itch intensely and often feel prickly or sting due to overheating. Heat rash is like tiny bumps surrounded by a zone of red skin.


Heat Rash Diagnosis


As the bumps burst and sweat is released, you may feel the prickly, or stinging, sensation that gives this condition its common name.


Heat Rash Symptoms and Signs


Heat rash occurs when the sweat gland ducts get plugged due to dead skin cells or bacteria such as Staphylococcus epidermidis, a common bacterium that occurs on the skin which is also associated with acne. The trapped sweat leads to irritation, itching and to a rash of very small blisters, usually in a localized area of the skin.


Heat Rash Treatment


In usual cases the rash of miliaria will resolve without intervention. Moreover, severe cases can last for a number of weeks and cause significant disability. General measures should be recommended to all patients, including moving to an air-conditioned environment if possible, avoiding sweat-provoking activities and occlusive clothing, and taking frequent cool showers.
