Treat heat pimples in children with home remedies

The condition we call heat rash occurs in adults and children when sweat builds up under the skin. When sweat glands are clogged, the sweat cannot evaporate, leading to the formation of small red or skin-colored blisters. These are often filled with fluid and resemble small pustules. The heat rash, which is still called a sweat rash or miliaria, is usually harmless and can heal on its own in a short time if the causative agent is removed. Children are more commonly affected than adults because their sweat glands are still developing.

Heat pimples are usually uncomfortable and itchy. In most cases, the appearance of the rash is not a reason to see a doctor. There are simple treatment options and prevention tips for people who frequently suffer from heat rash.

Thus, sun allergy is referred to as a reaction of the skin to UV light, and the heat rash can occur even after being indoors. The most common cause is heavy sweating, for example during sports or sleeping. In babies, heat pimples are often the result of clothing that is too warm or overheating.

Counteract heat rash with ice cubes

Since heat pimples are caused by heat, it’s not surprising that you can use cold to combat it. As soon as you spot the rash, you can put a few ice cubes in a bag or towel and use them to cool the affected area. Caution: never put the ice cubes directly on the skin, as they can burn it. If you don’t have ice cubes available, you can use a bag of frozen vegetables instead or simply treat the skin with cold water.

To use cornmeal against heat pimples, apply it directly to the itchy skin and leave it on for 10 to 15 minutes. After the exposure time, wash off the flour and you will immediately feel and notice the improvement of the skin appearance.

What else helps against heat pimples?

In addition to home remedies, some simple remedies from the pharmacy can also work well against heat rash. A thermal water spray, for example, is a must-have for the mom bag in the summer, as it quickly soothes the delicate skin so that it no longer itches. The spray consists only of minerals, trace elements and silica, so it has a quick cooling effect.

An over-the-counter zinc ointment from the pharmacy can also relieve the itchy skin irritation caused by heat pimples. The zinc oxide absorbs the sweat and dries out the formed pustules at the same time. Apply the zinc ointment against heat pimples in the evening so that it can work overnight. In the morning, the remains can be washed off with lukewarm water. Also, apply the ointment only selectively, i.e. directly on the affected areas, otherwise it can dry out healthy skin.
