It looks like tiny bumps surrounded by red skin. It usually happens on clothed parts of the body, such as your back, abdomen, neck, upper chest, groin, or armpits. And it usually gets better once your skin cools off.
Heat rash happens most often in hot, humid conditions. It's most common in infants. Active people, newborns in incubators, and people on bed rest with fever also are more likely to get it.
You can get a heat rash when you sweat too much. The ducts from the sweat glands in your skin become blocked. This causes the sweat to leak into the surrounding tissue, which leads to irritation and redness. You may feel the prickly, or stinging, sensation that gives this condition its name.
Treatment and Prevention
- Move to a cooler, less humid place.
- Don’t scratch your skin, or it could become infected.
- Keep the affected area dry.
- Don’t use ointments or creams that keep your skin moist.
- You can put powder on the rash to feel more comfortable.
- Use a fan.
- Wear clothes that aren’t tight and don’t trap heat and moisture.
