What does a humidifier do for babies?

Have you ever wondered how a humidifier, well…humidifies? Bobbie Medical Advisor, Lauren Crosby, MD, FAAP, explains that humidifiers add moisture to the environment by releasing water vapor into the air. This humidified air can reduce congestion caused by colds and/or allergies and also help dry skin.

Do babies benefit from cool mist humidifiers?

You bet! Dr. Crosby says babies benefit from a humidifier because they serve as an additional way to support certain health conditions like soothing airways and helping dry skin. “Pediatricians recommend the use of cool mist humidifiers instead of warm ones or hot water vaporizers for safety reasons,” says Dr. Crosby. She explains that the hot water or steam used in the warm mist humidifiers can burn your little one should they get too close or knock over the machine. 

When does a baby need a humidifier?

A popular question about baby humidifiers is this one: Should you only humidify during certain seasons or sickness? Dr. Crosby says humidifiers are recommended whenever a child has a cold, but especially during winter when the air is even drier. During the winter months, cold air holds less moisture than warm air. This causes the moisture from your body to evaporate quickly leading to more respiratory and sinus issues. 

This is why Dr. Crosby suggests a humidifier during the winter months. If your child is experiencing congestion, the moist air can help thin nasal discharge to make breathing easier and calm coughs. “It can also help treat a type of viral upper respiratory infection called croup and can soothe sore throats,” she says. 

Should a baby sleep with a humidifier every night?

If you’re wondering if you need to add a humidifier to your bedtime ritual, know that it’s not necessary for everyday use. Dr. Crosby explains that, “Overuse can lead to the development of mold either in the machine or in the room. And if a child has environmental allergies (especially to dust or mold or has asthma), a humidifier isn’t recommended as it might promote the growth of these allergens.” 

Are humidifiers good for newborn babies?

When it comes to using a humidifier for your newborn, Dr. Crosby says that typically they don’t need a humidifier. She does add that they can beneficial for newborns if your baby has a condition that would respond to the humidified air such as a respiratory infection or dry skin. If you’re unsure, your pediatrician can answer any concerns you may have. 

Should a baby have a humidifier in their room?

Dr. Crosby says it’s a good idea to have a humidifier in the home and ready to go if needed for respiratory infections or skin conditions like eczema. But it’s not necessary to run it all the time because that moisture builds up and can cause the growth of mold or other allergens, she reminds. Use it when you need it. For example, during the dry, winter months is a great idea.

Are humidifiers good for congested babies?

If you’re looking for tricks-of-trade when it comes to helping your congested baby breathe easier, a baby humidifier is super useful. “The moist air can ease breathing by thinning nasal mucus, calming coughs and soothing sore throats,” Dr. Crosby says. 

How important is it to clean your humidifier?

Very. The instructions are a good first place to check if you want to learn more about the care of your new humidifier. Best practices generally require taking apart the device daily. In addition, it’s important to change the filters as directed because this keeps mold or mineral deposits from building up. Dr. Crosby explains that distilled water (versus tap water) which has the minerals removed is recommended to use in the machine so there is less chance of build-up. 

Can you put essential oils in a humidifier?

While good-smelling essential oils may help your overworked mom-brain de-stress, it’s best not to use these in your baby’s humidifier. “Essential oils could irritate the airway, cause an increase in mucus production, cause coughing, or trigger wheezing in babies who have a history of wheezing, and potentially irritate the skin,” Dr. Crosby says. 

Is Vicks in a humidifier safe?

Vicks is a topical ointment containing some essential oils, so isn’t recommended to be used in a baby humidifier. Dr. Crosby reminds us that these oils can cause an increase in mucus production, wheezing, and coughing, and can worsen symptoms.

5 Expert tips on choosing the best humidifier

Mom, Cindy Kang, Founded the Hey Dewy brand of cool mist humidifiers when she struggled to find a lightweight, portable humidifier for herself and her kids. She shares expert tips with us here:

1- Cool Mist is best.  Hot water or steam from a warm-mist humidifier can burn your child if they are too close and can be unsafe if spilled by accident.  Cool mist is safe and effective.

2- Easy to use, Easy to fill, Easy to clean. For new moms who are already sleep deprived, the last thing you need is a large clunky humidifier that’s so big you have to walk down to the kitchen sink to fill (since it won’t even fit in your bathroom sink).  When it’s inconvenient to pour out and refill, you won’t do it often which leads to stagnant water that is left sitting for long periods of time. You try everything to clean it, shake that vinegar, but it’s just impossible to clean since you can’t touch all parts of the device, and you give up. Choose a humidifier that is small, lightweight, easy to empty & refill with one hand in your bathroom sink. The filter should be replaced every 4-6 months, depending on the frequency of use, so that everything is kept clean and good as new.

3- Find a small humidifier. Sometimes there’s a lot to fit on your nightstand, and the last thing you need is an ugly, clunky humidifier taking up the whole space. It’s better to choose a unit that is small, elegant, and has a beautiful illuminating night light to make sure bedtime is relaxing and calm.

4- A humidifier is not just for colds. Some children struggle with bloody noses or allergies and using a humidifier can be a game changer. During the winter months, especially when the heat is blasting, adding a humidifier can also help keep your little one’s skin from getting too dry and ease some eczema symptoms. 

5- Choose a humidifier that works for baby and mom.  New moms tend to fly to the moon & back for their kiddos, but often forget to take care of themselves. Adding a cool mist humidifier to YOUR nighttime routine is an easy way to incorporate some self-care while you sleep. When you start incorporating cool mist overnight, you may notice your skin feeling fresh & dewy (instead of tight and dry) when you wake up.  And instead of waking up with a dry, sore throat from the heater, you may feel rejuvenated from better quality sleep, ready to start the day.

Do you really need a humidifier?

Humidifiers can soothe congestion, provide relief for a pesky stuffy nose, and ease itchy dry skin. Having one on hand, to support your little one through these things can give you and your baby the comfort you need so you can both sleep better at night. You can have a humidifier in each bedroom of the house, as we all need added comfort from time to time.
