Sweat rash is a very common condition and can occur at any time. A natural yeast on your skin called candida causes irritation when your skin’s natural balance is altered. This can happen when sweat from your glands doesn’t evaporate completely.
Your skin can become itchy and irritable, with a red rash, a burning sensation or broken skin. Prickly heat, exercise, excessive sweating, changes in skin or body care products, synthetic fabrics and tight clothes can all aggravate sweat rash.
Some people have sensitive skin that reacts to the fragrances or perfume in some products. Or they may be allergic to other ingredients like alcohol and aluminium salts.
Sweat rash tends to happen in places where skin can rub together, such as the armpits, the backs of the knees, between the legs, the groin, and between and under the breasts. It can also happen where clothes rub against places where sweat is released, such as a sleeveless vest rubbing on your underarms.
Most types of sweat rash will clear up naturally. If you are sensitive to perfume or fragrance, or have a history of eczema, then it is a good idea to try a fragrance-free antiperspirant or deodorant. You could also try using an emollient or moisturiser alongside your antiperspirant or deodorant.
