The symptom is generally occurs when sweat glands get blocked in hot temperatures
The NHS has shared crucial advice about one symptom that’s especially prevalent during hot weather. While the skin sign is typically harmless and recovers on its own, it can be quite uncomfortable for those affected.
“Heat rash is common during hot weather,” the UK health service said on X, formerly Twitter. “It is uncomfortable – but usually harmless – and it usually gets better on its own after a few days.
“Here are some tips to help you check if you have heat rash – and advice on how to treat it.” As the NHS implies, heat rash is a common symptom that often occurs when sweat glands get blocked in hot temperatures.
Generally, this is caused by excessive sweating, which results in inflammation in the days following. Heat rash can appear as small, raised spots, mild swelling, or an ‘itchy prickly feeling’ on the skin.

This may look red on white skin, but can be more difficult to spot on brown or black skin, often seeming more grey or white. Although the rash can arise anywhere on the body and may spread, it cannot be transmitted to other people.
If you are suffering from heat rash, one of the best things you can do is keep the skin cool to avoid further sweat and irritation. The NHS explained that wearing loose cotton clothing, taking cool baths, drinking plenty of water and sleeping in lightweight bedding can all help with this.
Its advice also added: “To calm the itching or prickly feeling apply something cold, such as a damp cloth or ice pack (wrapped in a tea towel) for up to 20 minutes. Tap or pat the rash instead of scratching it. Do not use perfumed shower gels or creams.”
Normally, heat rash improves within a couple of days. However, anyone especially struggling should speak to a pharmacist, who is best placed to recommend specific treatments.
This may include a calamine lotion, antihistamine tablets or hydrocortisone cream, though it will vary on a case-by-case basis. If you are struggling with heat rash beyond just a few days, seek GP advice.
