What is a good treatment option for heat rash?
In most cases, heat rash will clear up on its own in a few days if the affected area is kept cool and dry. So cool your body in an air-conditioned room or with a fan, or take a cool shower or bath and let your skin air dry. If you can’t cool down right away and you continue to sweat, don’t add any antiperspirant, lotion, insect repellent, or powder to your skin — these may trap more sweat, making your symptoms worse. Once the skin is cool and dry again, don’t use any type of oil-based product, which might block your sweat glands. If your prickly heat does not go away within a few days, or if you develop an infection where the bumps have burst, you may need medication, so consult your doctor.
