What to Do About Heat Rash in Babies: Should I Be Worried?
Heat rash, or prickly heat, is a skin condition that happens when sweat can't escape due to blocked sweat pores. To prevent it, keep your baby out of overly hot, humid environments.
When you notice your baby has a heat rash, your alarms may go off. However, it’s a mild, temporary skin condition and shouldn’t worry you too much. Another name for it is milaria, or prickly heat.
It’s common in hot, humid climates and often affects newborns, especially babies under a year old. It’s caused by blocked sweat ducts. Because the sweat can’t get out, a rash or little blisters form, which are easily confused with other skin conditions.
So, should you worry about prickly heat?
While it’s good to do certain things to keep your baby comfortable, it’s not a serious condition and doesn’t lead to any other conditions.
Where does prickly heat come from?
Prickly heat is a skin reaction due to a dysfunction of the baby’s sweat ducts. It prevents sweat from leaving the body through their skin, leading to the formation of little red or white pimples or blisters.
It generally forms in areas that tend to get sweaty: the neck, chest, back, etc. However, you may see it in any area. Because of how it looks, some people assume that it comes from poor hygiene.
However, unlike other skin rashes, prickly heat does not come along with fever, and it tends to go away by itself without any treatment. Also, it’s not contagious and doesn’t usually leave marks or scars.

Babies only a few weeks old are more vulnerable to prickly heat, especially if they live in hot, humid climates. It’s also more common in babies with eczema or dry skin.
Generally speaking, risk factors include:
- Moderate or high fever,
- Excess heat,
- Bacteria (staphylococcus) on the skin,
- Use of pore-clogging powders and lotions.
Symptoms of prickly heat in babies
The main symptom of prickly heat is a rash. The rash will look like small blisters and give the skin a rough texture when you rub it.
Most of they time, you’ll see it in areas that contain more sweat ducts, like:
- Skin folds
- The forehead, eyelids, and cheeks
- Your baby’s torso
- The back
- The crotch and thighs
- Underarms and arms
Since prickly heat isn’t an infection, it doesn’t come along with fever. However, since it can be itchy, the baby may seem restless or fussy.
To rule out other problems, see a pediatrician; they’ll be able to find out what it is with a quick physical exam.
Tips to prevent and treat prickly heat in babies

How can I treat prickly heat in babies?
When you see the little bumps of prickly heat, you’ll want to do something about it. However, pediatricians often just advise normal hygiene, since it goes away in 2 or 3 days.
