1. Take a cool bath with cornstarch, oatmeal or baking soda added into to the water.

2. Gently clean the prickly heat rash area with a mild body soap to remove germs, sweat and dirt. After soaking in the tub, gently pat the area dry with a clean towel.

3. Apply hydrocortisone cream to relieve itching. Gently rub the cream into to skin until it is fully absorbed.

Tips & Warnings

• If the prickly heat rash does not go away in a few days, you may need to see a dermatologist. He can peel away the upper layers of skin with an ultraviolet light that will take away the plugs and promote sweating.
• To prevent prickly heat rash, try always to keep as cool as possible. Stay in the shade, take cool baths or showers if exposed to the heat for too long, wear loose clothing and drink plenty of fluids when you are outside. You can also apply a medicated heat powder to areas of skin most prone to prickly heat rash before going outdoors.
• Avoid scratching the rash, even though it itches. Scratching could lead to an infection that will require a doctor's visit and antibiotics.
