Prickly Heat (Heat Rash): How to Prevent and Soothe It

Prickly heat—also known as heat rash—is an irritating and uncomfortable skin condition that can really spoil warm weather, holidays, and time at the beach. If you’ve ever experienced the itchy red bumps and stinging sensation, you’ll know just how distracting it can be when all you want to do is enjoy the sun.

What Causes Prickly Heat?

Prickly heat occurs when sweat becomes trapped under the skin. This usually happens when pores are blocked, preventing perspiration from escaping properly. The result is inflammation, irritation, and those familiar itchy spots—especially in hot, humid conditions.

The good news is that there are simple, effective ways to both prevent prickly heat and calm symptoms if it does flare up.

How to Help Prevent Prickly Heat

1. Take regular cool showers
Cool water helps lower skin temperature and keeps pores clear. Avoid scented soaps or shower gels, as fragrances can irritate sensitive skin. Instead, use an unscented or vegetable-based soap. For extra relief, a dermatologically formulated cleanser such as Rona Ross Foaming Prickly Heat Gel Wash can help cleanse, cool, and soothe itchy skin.

2. Keep your body cool
Wear loose-fitting clothing made from natural fibres like cotton or, better still, linen. These fabrics allow the skin to breathe. At night, use lightweight bedding and keep rooms cool where possible. During the day, gently pat skin with a cool, damp towel if needed.

3. Stay well hydrated
Drinking plenty of water helps regulate body temperature and supports healthy skin function.

4. Consider antihistamines
In some cases, a pharmacist may recommend antihistamine tablets to help reduce itching and irritation.

5. Choose the right sunscreen
Use a non-comedogenic sunscreen—one that won’t block pores. EVY Technology Sunscreen Mousse is clinically proven, provides 5-star protection, and is designed to work with the skin rather than sit heavily on the surface. It’s suitable for the whole family and may help reduce sun-related skin reactions, including prickly heat.

Treating Prickly Heat When It Appears

6. Cool and cleanse the skin
Take a cool shower using an unscented soap or a specialist wash such as Rona Ross Foaming Prickly Heat Gel Wash.

7. Reduce heat exposure
Move into the shade or a cool, air-conditioned space. Lightly pat the skin with a cool, damp towel—avoid rubbing.

8. Apply a calming lotion
A calamine-based product such as Rona Ross Prickly Heat Lotion helps soothe itching, calm irritation, and lightly moisturise the skin. It also works well as an aftersun, cooling and hydrating without added fragrance.

9. Seek pharmacy advice if symptoms are severe
In persistent or more severe cases, a pharmacist may recommend a mild hydrocortisone cream.

A Simple Rule of Thumb

When dealing with prickly heat, keep things cool, light, and fragrance-free. Give your skin space to breathe, and it will usually settle quickly—letting you get back to enjoying warm weather the way it’s meant to be enjoyed.
