What is Sweat Rash?

Sweat rash (medically known as candidal intertrigo or intertrigo) is a superficial inflammation of the skin that is often infected by Candida yeasts and bacteria. It usually shows up as a red rash on your skin. Candida can multiply when the condition of your skin changes, for example if your sweat is trapped and the area becomes warmer or more moist than normal.

Sweat rash most commonly appears where your skin rubs together and where there’s less air circulation such as under your arms, on the backs of your knees, under your breasts, in the groin area, between abdominal skin folds and in the spaces between your fingers and toes.

Sweat rash most often occurs in individuals that are overweight, have diabetes, have HIV or are confined to bed for a long period of time.
