Heat Rash

What are the symptoms of heat rash in children and adults?

The common symptoms of heat rash are red bumps on the skin, and an itchy or prickly feeling to the skin. These are due to inflammation of the superficial layers of the skin (the epidermis) and the prickly sensation is similar to the feeling of mild sunburn.

The symptoms of heat rash are the same in infants and adults; however, since an infant can't complain about the rash sensation, he or she may be fussy.

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) 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. Continue Reading
