DR. LISA RHODES: Hi, I'm Dr. Lisa Rhodes with Westlake Dermatology and Cosmetic Surgery. Heat rash or miliaria rubra is a common eruption that occurs in the summertime usually in hot, humid climates. Usually, it shows itself as a little red bumps in areas where the sweat's not evaporating. It's very common in young children. The best treatment is to get cool. Keep the areas dry. You can use cornstarch powders or other powders that absorb that sweat and then put some fans on, get to a cooler climate and try keep your body temperature a little bit lower. That should help the most.
