• Location. Heat rash of the forehead can be caused by oil or ointment on the hair. Heat rash of the face of a breastfed baby can be caused by lanolin put on the nipples. Heat rash of the chest can be caused by menthol ointments put on for coughs.

Care Advice for Heat Rash

1. What You Should Know About Heat Rash:
   • Heat rash is caused by blocked-off sweat glands.
   • It's common in hot, humid weather.
   • Here is some care advice that should help.
2. Cooling the Skin:
   • Cool off the skin to treat and prevent heat rash.
   • For large rashes, give your child a cool bath without soap. Do this for 10 minutes. (Caution: Avoid any chill.) Let the skin air-dry. Do this 3 or more times a day.
   • For small rashes, put a cool, wet washcloth on the area. Do this for 5 to 10 minutes. Then let the skin air-dry.
   • Dress in as few layers of clothing as you can.
   • Lower the temperature in your home if you can.
3. Sleeping Cooler:
   • When your child is asleep, run a fan in the bedroom.
   • During sleep, have your child lie on a cotton towel to absorb sweat. (Note: Only for older children age over 1 year.)
4. Steroid Cream for Itching:
   • Use 1% hydrocortisone cream (such as Cortaid). No prescription is needed.
   • Put it on itchy spots 3 times per day.
   • Avoid hydrocortisone ointment.
   • Calamine lotion can also work.
5. Do Not Use Ointments:
   • Avoid all ointments or oils on the skin. Reason: They can block off sweat glands.
