Heat rashes in children may be of many types and cause skin irritation. Thankfully, it is not considered a serious condition. These rashes usually affect the skin in the body parts that remain sweaty for a long duration. They are self-limiting and get resolved in a few days (1). Continue reading this post as we tell you about the various types of heat rashes, the causes of heat rashes in children, their symptoms, and some home care tips for managing and preventing such rashes.

Types And Symptoms Of Heat Rashes

1. Miliaria rubra

This appears as red to pinkish bumps without any pus.

These are a few millimeters in size and appear as blisters.

The bumps appear on the fold of neck, forehead, creases of elbow and knee.

They also appear in the armpits and groin areas (2).

These tend to go away after a few days when the body temperature comes to normal.

2. Miliaria crystallina

Is the least severe of the three types.

Occurs in neonates as their sweat glands are yet to mature.

1-2 diameter bumps with clear liquid appear on the neck, axillae, and face (3)

Cooling down the body and avoiding excessive clothing will reduce the rashes within a few days.

3. Miliaria profunda

It is not common in children and might develop if miliaria rubra is ignored.

Flesh-colored larger bumps appear on the skin.

They might itch a little (2).

Sometimes, these rashes might require a visit to the doctor. But first let us see what causes heat rashes in children?

Causes Of Heat Rashes

A heat rash occurs due to the trapping of sweat within the sweat pores, and the blocking the sweat gland. Here are a few reasons which might cause blockage of the sweat pores. Heat rash, also known as prickly heat and miliaria, would get resolved within three to four days as soon as your child’s body cools down. However, it can cause itching and prickliness that could irritate the children. Read on to how you may speed up the healing process.

Home Care And Prevention Of Heat Rashes In Children

Most cases of prickly heat do not require a visit to a doctor or medication. You can take remedial steps at home when you notice heat rash. These home care tips focus on preventing the accumulation of sweat and cooling your child’s body.

Dress your child in fewer layers of clothes made from natural fabrics like cotton. Cotton absorbs sweat and allows ventilation.

If your child has a heat rash, you could consider letting them wear only one layer of clothing to let the body stay cool.

Cool baths might help soothe itching and the prickly feeling caused by a heat rash.

Let the child have a bath with cool water, without soap or shower gel.

Keep the water cool to touch and not too cold since that can cause chills.

Pat dry the skin with an absorbent towel and let the child stand under a fan to allow the rest of the water to dry.

Keep the fan running at maximum speed in your child’s room during summers.

If it is hot and very humid, then use an air conditioner to make the temperature comfortable enough to prevent excessive sweating and subside any existing heat rashes.

Several over-the-counter prickly heat dusting powders help contain itching and absorb sweat.

Buy a prickly heat powder that is safe for your child’s age and apply the powder on the affected/prone areas.

Let the child stand under the fan after coming back from the outdoors. It helps evaporate the sweat, thus mitigating the chances of prickly heat.

Give your child plenty of water to drink, as that could help bring down the body temperature and prevent dehydration.

If the itching is severe, then make an appointment with your child’s doctor.

When To Take A Child To A Doctor?

If the rashes do not subside with three to four days and if the following symptoms accompany a heat rash, then take the child to a doctor:

Fever Excessive itching Vomiting and diarrhea Extreme lethargy or dizziness Loss of appetite Pus in the blisters Swollen lymph nodes
