What should you know about body heat and itching?

Heat and sweating may irritate skin or trigger small itchy bumps, especially in folds and areas covered by clothing. Dry, cracked skin can itch more when the weather is hot or indoor air is dry, as in Asteatotic Eczema. Atopic Dermatitis and Psoriasis can flare with heat, sweat, or friction. A new product may cause Contact Dermatitis; moist folds can develop a Skin Yeast Infection. Night-time itch or itch affecting several household members can occur with Scabies. Hives are raised, transient itchy welts, while Lichen Planus may produce persistent itchy bumps.

Move to a cooler environment, rinse sweat away with lukewarm water, pat dry, and wear loose breathable clothing. Use a fragrance-free moisturiser after bathing and avoid new fragranced products, harsh scrubs, and hot showers. Keep nails short to reduce skin injury from scratching. Do not share towels or bedding if a contagious cause is possible, and ask a pharmacist or clinician before using a medicated cream on a widespread, broken, or facial rash.

Arrange a review if itching persists, repeatedly returns, disrupts sleep, or comes with scaling, cracks, oozing, pain, or spreading redness. Seek urgent help for swelling of the lips or tongue, breathing difficulty, faintness, or a rapidly spreading rash. Fever, pus, severe tenderness, or blistering also warrants prompt assessment.

Describe where the itch began, whether heat or sweating triggers it, and any new products, medicines, travel, or household symptoms. Ask which condition fits the rash, whether testing is needed, and how long to try treatment before follow-up.
