Sweat rash

Sweat rash is common during the dry season, and can affect you frequently if you play sports regularly. It normally shows up as a red rash on your skin.

Also known as candida intertrigo, sweat rash is a superficial skin inflammation caused by yeast and bacteria. Candidiasis develops on the areas of your body where moisture becomes trapped, as Candida yeast spreads easily when your skin condition changes. For example, if your skin becomes warmer when exposed to humid conditions.¹

Sweat rash symptoms

You might have a sweat rash if you notice:

Red rash with scaling on the periphery
Stinging or burning sensation on skin
Cracked skin in the space between your fingers or toes
Blisters

You should see a doctor if:

Your sweat rash persists
Your symptoms are caused by being overweight, for advice on losing weight
You are pregnant or elderly ³

Understanding sweat rash

Humidity, friction and lack of ventilation all contribute to sweat rash. That's why you will find that it shows up in skin folds or areas that normally stay covered. It's also why physical exercise can make symptoms more pronounced.⁴

Sweat rash treatment

It’s always best to start treatment for your Candida-associated sweat rash early with topical products like creams or sprays.

Depending on the severity of your symptoms, you may be recommended treatment using an antifungal product, or a milder anti-inflammatory product such as hydrocortisone.⁵
