Heat rash is usually uncomfortable but harmless, typically clearing up on its own within a few days.
How to Identify Heat Rash
Common symptoms include:
- Small, raised bumps
- Itchy or prickly sensation
- Mild swelling
On lighter skin, the rash appears red, while on darker skin, it may be less noticeable or appear grey or white.
Both adults and children can experience these symptoms, and the rash can form anywhere on the body. It is not contagious.
Causes of Heat Rash
Heat rash commonly occurs when sweating becomes excessive. Blocked sweat glands can trap sweat under the skin, leading to the rash after a few days.
Babies are particularly vulnerable to heat rash since they have a harder time regulating their body temperature compared to adults or older children.
Self-Treatment for Heat Rash
To manage heat rash, the focus is on cooling the skin and reducing sweating:
To cool your skin:
- Wear loose-fitting cotton clothing.
- Use lightweight bedding.
- Take cool baths or showers.
- Drink plenty of fluids to stay hydrated.
To ease itching or prickliness:
- Apply a cold compress, like a damp cloth or ice pack (wrapped in a towel), for up to 20 minutes.
- Gently tap or pat the rash instead of scratching.
- Avoid scented shower gels or creams.
