What Is a Sweat Rash?
Sweat rash is a rash developing when the body heats up and perspires, and the rash is usually caused by some minimal to significant blockage of the sweat glands. Many people know this rash by other names like prickly heat, and medically it’s referred to as miliaria. Mild forms of heat or sweat rash are known as miliaria rubra, but severe forms, which are fortunately rare, are called miliaria profunda. The type of rash that develops with sweat can differ in location on the body. Very often it appears in patches, usually in parts of the body that are cut off from air, like in between skin folds. Areas under the belly, in the underarms and under the breasts are prime possible rash locations. Usually the rash doesn’t spread, and simply looks like a collection of red whiteheads or blisters, but if the person is severely overheated, the rash could be present on a significant part of the body or in several different large patches.
