What is heat rash?

Heat rash is a skin rash which appears in response to the child being very hot – in fact he or she may be too warm.

It is a pimply, red skin eruption, which can appear when your child overheats in hot or humid weather. It is most noticeable in folds in the skin and on parts of the body where clothing or nappies fit snugly, such as the chest, back, stomach, neck, genital area and buttocks. It may also spread across the head and forehead if your child wears a hat.

What causes heat rash?

Heat rash seems to arise when the child is sweating a lot. It is possible that there is some sort of irritation set up on the skin when the child sweats so much that the pores clog up and the sweat cannot be released as fast as it builds up.

Tight, or heavy clothing can trap sweat, and contribute to the rash. Heat rash can also occur if the child has a high fever and is sweating heavily.

Can heat rash be prevented?

Keep your child comfortably cool and avoid dressing him or her in tight fitting clothing in hot weather. Some people believe that natural fabrics such as cotton allow easier movement of air across the skin and so less sweating than artificial fibres.

If it is very hot, make sure that your child plays inside or in the shade. Give him or her plenty of liquids to prevent dehydration.

Corn starch or talcum powder in skin creases can also help to prevent heat rash.

How is heat rash treated?

Start by cooling your child down. Loosen or remove tight clothing and move him or her into a cool, shady place. Cool the area affected by the rash with cotton clothes soaked in cool water. A tepid bath can also help. Let the air dry the skin as much as possible and avoid using towels since the rubbing can irritate the skin further.

Avoid ointments or lotions since they can trap sweat as well and exacerbate the situation.

What is the outcome of heat rash?

Heat rash is not a serious condition and the child will get better without specific treatment in most cases.

There may be very superficial peeling of the affected skin area as the rash gets better.

When to call the doctor

Call your doctor if your child has a fever which does not respond to medication or other cooling techniques.

If the rash does not disappear in three to four days, take your child to the doctor to check the diagnosis.
