Fungal Skin Infections in Hot Weather: Ringworm, Athlete's Foot and Jock Itch
Heat and sweat help fungi grow on the skin. Learn how to recognise ringworm, athlete's foot and groin rashes, how they are treated and how to prevent them.
Quick answer
Fungal skin infections thrive in hot, humid conditions and cause itchy, red or scaly patches, often ring-shaped, between the toes or in the groin. Most clear with antifungal creams used for the full recommended time, plus keeping the skin clean and dry. See a GP if the rash is spreading, on the scalp or nails, not improving after two weeks of treatment, or if you have diabetes.

Fungi love warm, moist skin, which makes infections common in the UAE climate, especially among people who sweat at work or wear closed shoes all day.
Common types
- Ringworm (tinea corporis): a red or darker, itchy, ring-shaped patch with a clearer centre. It is a fungus, not a worm.
- Athlete's foot (tinea pedis): itchy, peeling or cracked skin between the toes.
- Jock itch (tinea cruris): an itchy rash in the groin and inner thighs.
- Scalp ringworm: scaly patches and hair loss, more common in children.
- Nail infection: thick, discoloured, crumbly nails.
Treatment
- Skin infections usually respond to antifungal creams from a pharmacy. Continue using the cream for the full time on the pack, often for a week or two after the rash disappears, to stop it coming back.
- Scalp and nail infections usually need antifungal tablets prescribed by a doctor.
Don't use steroid creams on a fungal rash unless a doctor advises it; they can make the infection spread.
Prevention
- Shower after sweating and dry skin thoroughly, especially between the toes and in skin folds.
- Wear loose cotton clothing and change socks daily.
- Wear sandals in shared showers and pool areas.
- Don't share towels, combs or shoes.
- Treat pets with skin patches, as animals can pass on ringworm.
When to see a GP
- The rash is spreading or not improving after two weeks of treatment
- The scalp or nails are affected
- You have diabetes or a weakened immune system
- The skin becomes hot, swollen and painful
Frequently asked questions
Is ringworm contagious?
Yes. It spreads through skin contact and shared items. Cover the area and wash hands after touching it.
Why does athlete's foot keep coming back?
Stopping treatment too soon and damp shoes are common reasons. Finish the full course and let shoes dry out between wears.
