Usually, heat rash is composed of small, prickly, itchy bumps with a halo around them. This type of heat rash is called miliaria ruba, or prickly heat.
Other than the discomfort, heat rash really isn’t a health concern. However, if left untreated, the condition can cause pus-containing blisters (miliaria profunda) and lead to infection.
A heat rash most often appears:
- In the folds of the skin, including armpits and elbow creases
- Under the breasts
- In the groin area
- On the legs, chest, arms, neck, and back
Although a heat rash usually goes away on its own in a few days, some simple home remedies and over-the-counter products can help treat the rash or, even better, prevent it in the first place.
