How to Treat a Heat Rash--Fast Remedies


Stay indoors. Hot, humid temperatures can trigger a heat rash. Limit outdoor activity when the humidity is high and use your air conditioner to maintain a comfortable temperature in your home.


Keep your skin cool. Shower after participating in activities that induce sweating, such as exercising, washing your car, gardening or mowing the lawn.


Alter your attire. Wearing tight-fitting clothes can promote sweating and prolong a heat rash. Choose loose-fitting outfits to stop moisture retention and help treat a heat rash.


Use an antibacterial body wash. "The Doctor's Book of Home Remedies II" recommends the use of a mild antibacterial wash to cleanse your skin. Eliminating bacteria on your skin reduces skin irritation and unclogs pores.


Apply an anti-itch cream. Itching may accompany a heat rash. Use an OTC anti-itch cream such as Calamine lotion to stop irritation.
