Common, itchy and harmless—heat rash can be a pain. Here’s how to spot, treat and prevent this warm weather ailment.
As temperatures rise, so do incidents of heat rash, also known as prickly heat. Heat rash is caused when sweat gets trapped in the skin by clogged sweat glands or pores. That backup inflames surrounding tissue, causing a pink rash that can be uncomfortable. It may look like a spread of pimples or dots and typically itches or feels like pens and needles.
Even though it may feel bad, heat rash is typically harmless. It most commonly occurs in places where sweat tends to accumulate, such as the neck, armpit, chest, elbow creases, groin or area under the breasts. As a result of this sweat accumulation, those areas may become too warm for comfort due to friction or clothing.
To treat heat rash, remove excess layers of clothing and move to a cool, dry spot. Avoid using creams, powders or other topical treatments. They may make clogging worse and trigger prolonged discomfort.
Heat rash often clears up on its own within a few days. If you notice any signs of infection, such as fever, pus or red lines leading away from the rash, visit your local urgent care center immediately. The same goes for cases that don’t improve in three to five days or that spread to other parts of the body.
