Prickly heat is not a serious condition, and rarely requires any specific treatment. Most rashes will disappear naturally after a few days.

However, if you have prickly heat, there are a number of steps, such as those that are listed below, which may help to ease your symptoms.

• Avoid excessive heat and humidity where possible. Try to spend some time in the shade, or try taking a small fan out with you. Being exposed to heat will only make you sweat more, and could make your rash worse.
• Wear loose cotton clothing. Avoid wearing synthetic fibers, such as nylon and polyester, because they trap heat more easily than natural fibers.
• Keep your skin cool. Taking a cool bath, or shower, will help prevent sweating and will also soothe your skin.
• Calamine lotion can be used if your skin feels sore and irritated. It will help cool and soothe your skin. You can buy it at most pharmacies.
• Hydrocortisone cream can be used if your rash feels particularly itchy and irritated. You can buy low-strength hydrocortisone cream from your local pharmacy. However, avoid using this cream on your face, and always follow the instructions on the packet.
