Heat Rash: This Helps Against the Annoying Rash

Itchy heat pimples ruin the most beautiful summer day in no time at all. But what is behind the annoying rash and how do you avoid the blisters? We reveal everything you need to know.

This is how heat rash occurs

Heat rash is particularly common in summer. In contrast to sun allergies, this rash has absolutely nothing to do with UV radiation, but with heat and the associated increased activity of the sweat glands.

Because: The pimples develop when the perspiration that escapes in these cases is not properly transported away. The sweat does not evaporate in the air but gets stuck in the glands. A phenomenon that can affect adults, children, and babies alike.

The result: Colorless small blisters form that burst easily (Miliaria cristallina), or inflamed red pustules (Miliaria rubra) that weep, itch and even hurt. Pimples develop particularly easily where there are many sweat glands, for example under the armpits, in the back of the knees or on the décolleté.

The reason for the clogged pores is simply wrong or too tight clothing. It is not very breathable and prevents sweat from evaporating on the skin’s surface.

How to prevent the rash

Breathable fabrics minimize the risk of this annoying rash. So dress yourself, your child or your baby primarily in light natural fibers such as fine merino wool, silk or cotton, especially in summer. Breathable functional clothing is recommended for sporting activities.

In addition, when it’s hot, it’s best to wear loose-fitting pieces that gently caress your skin. Also, stay in the cool shade on hot days so as not to heat up your skin unnecessarily.

When it comes to skincare in the summer, also use light lotions and creams with moisturizing active ingredients such as aloe vera. On the other hand, avoid overly nourishing, fat-enriched body butters and oils. They promote heat build-up on the skin.

Treat heat rash properly

Colorless pimples usually disappear on their own after a few hours as soon as the build-up of heat on the skin is eliminated by changing clothes, for example. Treat red, inflamed pustules with anti-inflammatory zinc ointment to heal quickly. Important: In the case of a severely painful or prolonged rash, always consult a dermatologist.
