Who is at risk for heat rash?

Newborns, infants, the elderly, and obese individuals with large areas with skin-on-skin contact areas (for example, a large overlapping area of abdominal fat or panniculus) are at risk for developing heat rash. They all are especially at risk if they are immobile for long periods of time and parts of the skin aren't exposed to circulating air, which results in the inability of the sweat ducts to "breathe" (evaporative cooling).

Heat rashes are more common in places with hot, humid, climates because people sweat more.

Intense exercise associated with lots of sweating may cause a heat rash, especially if the clothing worn does not allow adequate air circulation.

How is heat rash diagnosed?

The diagnosis of heat rash or prickly heat is made by physical examination. Knowing that the rash appears during sweating or heat, appreciating the location on the body (in skin creases or where clothes fit tightly) and seeing what the rash looks like is enough to make the diagnosis. As with many rashes, the health care professional may look at the involved skin and because of previous experience, immediately make the diagnosis.
