Noticing that your baby has a rash can be alarming. The rash may be causing your little one discomfort. Worse still, you might not know where it came from. While there are many skin conditions that babies often experience, heat rash is one of the most common. In fact, it may even be the first type of rash to affect your child.
In this article, the baby experts at Mustela will explain everything you need to know about baby heat rash. We’ll tell you exactly what it is and how to identify it, as well as how to prevent and treat it. Follow the easy tips we provide in this post and your baby’s skin will be back to normal in no time.
What Is Baby Heat Rash?
As the name suggests, heat rash is a skin condition that develops when your baby’s skin gets too hot. More specifically, heat rash is caused when sweat gets stuck in your baby’s pores.
When your baby’s body becomes hot, their skin begins to produce sweat (which is a cooling mechanism for the human body). Normally, drops of sweat would simply be released through pores. However, babies have tiny pores that can easily become clogged. Heat rash is the result of sweat getting caught in those small pores as it tries to reach the surface of your little one’s skin.
Summer is the most common season for heat rash because we all sweat a bit more during the hot summer months. Humid climates can also contribute to heat rash. But this skin condition doesn’t only occur when the temperature is high! It can also form when it’s cold, especially if your baby is wearing many layers of clothing. Remember to de-layer when you go indoors.
Fortunately, heat rash isn’t a serious condition. It’s perfectly normal for babies to get heat rash, and with proper treatment, it usually goes away after a few days.
How Can I Tell If My Baby Has Heat Rash?
- Patches of red, itchy skin
- Tiny bumps or pimples
- Slight inflammation or puffiness
- Irritation and discomfort
If you’ve noticed these telltale signs on your baby’s skin, they may be suffering from heat rash. Keep an extra close eye on your baby’s chest, neck, diaper area, or armpits. Your baby is more likely to develop heat rash in these places because they are the areas that usually produce the most sweat. Clothing also tends to fit tightly around those parts of their body.
So how can you tell baby heat rash apart from other skin conditions, like eczema or cradle cap? Eczema will normally cause flaking and feel rough to the touch. Heat rash, on the other hand, causes small bumps or tiny blisters to form on the surface of your baby’s skin. Cradle cap also causes red, flaky skin, but this condition can only form on your baby’s head and forehead.
How Can I Prevent My Baby From Getting Heat Rash?
If your baby hasn’t yet developed a heat rash, consider yourself lucky! It’s a common ailment that most babies suffer from at one point or another. But this doesn’t mean baby heat rash is inevitable! There are several simple steps you can take to prevent it.
Keep Your Baby Cool
If your baby is nice and cool, their body doesn’t need to sweat. No sweating means no heat rash! If your baby’s cheeks become flushed, it’s probably a sign that they’re a bit too hot. Whenever you notice rosy red cheeks, move your baby to a cooler area.
Don’t Spend Too Much Time In The Sun
While there’s nothing wrong with enjoying some sunshine with your little bundle of joy, don’t spend too long in the sun. Too much direct sunlight can cause sunburn and poses dangers for your baby’s sensitive skin. The heat the sunlight brings can also lead to baby heat rash.
Keep Your Baby’s Skin Dry
Moisturized skin is generally a good thing, but too much moisture can irritate your baby’s skin. This is especially true when heat is added to the mix. To prevent heat rash, make sure you are using a moisturizer formulated for your baby’s skin type so no excess moisture remains. Always make sure your baby is dry before dressing them or putting on a new diaper.
Dress Your Baby In Layers
Babies are a bit fickle when it comes to temperatures. They get cold easily, but they can also get too hot very quickly. The easiest solution is to dress your little one in layers. Whenever your baby seems hot, simply remove a layer. When you notice that your baby is feeling cold again, just add another layer.
What Are The Best Ways To Treat Baby Heat Rash?
As we mentioned earlier, heat rash is easy to treat and normally goes away in two to three days, if not sooner. Here are the best ways to treat your baby’s heat rash.
Let Your Baby’s Skin Breathe And Dry Out
It’s extremely important to keep the areas affected by heat rash completely dry. This is essential to get rid of your baby’s heat rash. Why is keeping your little one’s skin dry so important? As we explained earlier in the post, heat rash is caused by sweat clogging your baby’s pores.
Letting your little one’s skin breathe is an excellent way to clear up heat rash because it dries their skin. Allow your baby to be naked (or just in a diaper) for as much time as possible until the rash goes away.
Adjust The Temperature In Your Home
One easy way to treat heat rash is to lower the temperature in your home. This will help keep your baby’s skin cool and dry, which will help the rash to clear up on its own. It’s particularly important to make sure your baby isn’t too hot while they sleep. Try turning a fan on low if your baby’s room tends to be too warm at night.
Apply Skin Care Products Made Especially For Babies
Using the right cream can work wonders when treating your baby’s heat rash. Just be sure to choose skin care products that are safe to use with infants and toddlers. Stelatria is an excellent product to use, as it will soothe your baby’s skin while also helping the rash to heal.
Use Mild Cleansers Rather Than Soaps
Most soaps are simply too harsh for a baby’s delicate skin and should be avoided whenever possible. Instead, use mild cleansers to bathe your baby as part of their daily hygiene routine. This is a great way to treat heat rash and will help keep your baby’s skin healthy. Mustela offers several baby-friendly cleansers, like our Soothing Cleansing Gel and our Gentle Cleansing Gel.
Be Gentle With Your Baby’s Skin
This may seem obvious, but it’s worth repeating: always be gentle with your little one’s skin! Be careful not to rub or scratch your baby’s skin when dressing them. Always pat (rather than rub) your baby dry with a soft towel and only use gentle skin care products that are specially designed for a baby’s delicate skin.
Dress Your Baby In Loose Clothing
Loose-fitting clothing won’t rub against your baby’s skin and is, therefore, less likely to further irritate heat rash. Tight clothing may inflame the rash by rubbing against the affected area or by making your baby sweat even more. Try to dress your baby in loose clothing made from soft, breathable fabrics.
Give Your Baby Plenty Of Fluids
While your little one is fighting off a heat rash, they may be dehydrated. There’s very likely a lot of moisture locked in their skin and the rash. Plus, their body is working overtime to unclog their pores and eliminate the rash! Give your baby plenty of fluids so that their body has the hydration it needs until the heat rash is gone.
Limit The Time Your Baby Spends Tightly Wrapped Up
Although babies love the feeling of being swaddled, you should skip this comforting activity while fighting your baby’s heat rash. It’s also best to limit the time your baby spends in carriers, strollers, and car seats. These places can inflame heat rash, so it’s best to avoid them until your little one’s skin is back to normal.
Baby heat rash is never fun, but it’s very common and easily treatable. Just follow the simple tips we’ve outlined above and your baby’s skin will be soft and smooth again in just a few days.
