11. Go for the Meds
Oral antihistamines, like Benadryl, can help reduce the itching. This OTC medication is a medicine cabinet staple. It’s great for many types of allergic reactions and skin irritations.

12. Don’t Chafe
Avoid chafing. Use a clean cotton washcloth to separate body parts that might ordinarily rub together. Heat rash should disappear within a few days. If it persists or is accompanied by a fever, it’s time to see the family physician.
