The bumps or blisters may swell, become irritated or itchy, and redden as the rash progresses. Prickly heat may spread on the body, but it is not infectious. Under normal conditions, there is no way to pass the rash on to other people.
How do you stop heat rash from spreading?
How can heat rash be prevented?
- Avoid exercising in hot, humid weather.
- Wear loose clothing made of breathable fabrics like cotton.
- Use air conditioning.
- Keep the skin clean with frequent baths or showers to prevent sweat glands from becoming clogged.
- Reduce the amount of overlapping skin-on-skin (fat or weight loss)
How long does prickly heat last?
Prickly heat should subside within a few days. Often, it goes away as soon as you are dry. If the home remedy doesn't work, or you keep getting a heat rash, take a picture of the rash for your doctor to see.
