Hot weather can be enjoyable until your skin starts reacting to the heat. Heat rash, also known as prickly heat, is a common skin condition that affects both children and adults, especially during periods of intense heat and humidity. While it is usually harmless, it can be uncomfortable, itchy, and frustrating.
The good news is that heat rash often clears up with simple home care and a few lifestyle changes.
What Is Heat Rash?
Heat rash happens when sweat becomes trapped under the skin because the sweat ducts are blocked. This leads to small bumps, redness, irritation, and an uncomfortable prickling sensation on the skin.
It commonly appears on areas where sweat builds up, such as the neck, chest, back, under the breasts, groin area, elbow and skin folds
Babies are especially prone to heat rash because their sweat ducts are still developing.
Common symptoms
Heat rash can look different from person to person, but common signs include:
- Tiny red or clear bumps
- Itching or tingling sensation
- Mild swelling
- Red patches on the skin
- A prickly or stinging feeling
In severe cases, the rash may become painful or infected if scratched repeatedly.
How to Treat Heat Rash
- Stay cool
The first and most important step is to cool the skin. Move to a well-ventilated or air-conditioned area if possible. Heat rash usually improves once the body temperature drops and sweating reduces.
- Wear loose clothing
Tight clothing traps heat and sweat against the skin. Choose lightweight cotton fabrics that allow the skin to breathe comfortably.
- Keep the skin dry
Gently pat sweaty skin dry with a soft towel. Avoid rubbing the affected area because this can worsen irritation.
- Take cool baths or showers
A cool bath or shower can soothe the skin and reduce inflammation. Avoid hot water, as it may further aggravate the rash.
- Use calamine lotion
Calamine lotion may help relieve itching and discomfort. Apply lightly to the affected area if the skin feels irritated.
- Avoid heavy creams
Thick creams and oily products can block pores and trap more sweat. Use light skincare products during hot weather.
- Do not scratch
Scratching can break the skin and increase the risk of infection. If the itching becomes severe, an antihistamine recommended by a pharmacist may help.
When to see a doctor
Although heat rash is usually mild, medical attention may be needed if:
- The rash lasts more than a few days
- There is pus or increasing pain
- You develop a fever or chills
- The skin becomes swollen or infected
- A baby seems unusually uncomfortable or distressed
Tips to prevent heat rash
Prevention is often easier than treatment. Here are a few helpful habits:
- Stay hydrated
- Avoid excessive sun exposure
- Wear breathable fabrics
- Keep rooms cool and ventilated
- Shower after heavy sweating
- Avoid overdressing babies and children
