Overview

• The NHS guidance highlights that heat rash is a common but generally harmless condition that usually clears up on its own within a few days.
• The rash appears as small, raised bumps with a prickly, itchy sensation and may look red on lighter skin but greyish or white on darker skin.
• Self-care measures recommended include wearing loose cotton clothing, taking cool baths, staying well-hydrated and using lightweight bedding.
• To soothe symptoms, apply a cold compress for up to 20 minutes, tap the affected area instead of scratching and avoid perfumed shower gels or creams.
• Those with persistent or troublesome symptoms are advised to consult a pharmacist for treatments like calamine lotion, antihistamines or hydrocortisone and to see a GP if it lasts beyond a few days.
