Mouth Breathing: Is It Bad For Your Health?

Mouth breathing, often due to congestion or habit, can lead to dry mouth, bad breath, and increased risk of infections; learn about the causes, risks, and ways to encourage nose breathing.


Do you ever catch yourself breathing through your mouth without really thinking about it? Most of us are supposed to breathe through our noses, but sometimes we end up relying on our mouths, maybe because our noses are stuffy or for other reasons. Is this something we should worry about? What’s the deal with mouth breathing anyway? We’re gonna dive into all of that, so stick around.

When Does Mouth Breathing Happen?

Okay, so you might find yourself breathing through your mouth now and then, especially if you’ve got a stuffy nose, maybe from allergies or a cold. Or, um, when you’re pushing yourself hard during exercise, your body might just need more oxygen, like, ASAP so you start breathing through your mouth to get it faster.

Some conditions can actually make you breathe through your mouth to get enough air. But, if you’re constantly breathing through your mouth, like all day or while you sleep, it can cause some problems.

Mouth breathing is pretty common in kids too and can be caused by things like enlarged tonsils or adenoids, allergies, or even just habits. For adults, it might happen because of a deviated septum, nasal polyps, or just congestion caused by different health issues.

Are You a Mouth Breather?

You might not even realize you’re breathing through your mouth instead of your nose, especially when you’re asleep. But there are some telltale signs that might pop up that’ll suggest you’re doing it:

  • Dry mouth
  • Sore throat
  • Bad breath
  • Snoring
  • Chronic fatigue
  • Brain fog
  • Dark circles around your eyes
  • Irritability

For kids, watch out for these signs:

  • Poor performance in school
  • Hyperactivity
  • Swollen tonsils, especially at night
  • Snoring
  • Chapped lips
  • Trouble focusing
  • Nightmares

Here’s something interesting to consider, beyond what we’ve discussed: the impact of mouth taping. We haven’t touched on it yet, but some folks are exploring whether taping their mouths shut at night can encourage nasal breathing. It’s a method that’s gaining traction, but, like any health practice, it’s got its proponents and skeptics. It’s something to discuss with a healthcare professional.

Why Do We Breathe Through Our Mouths?

There’s a bunch of different reasons why you might be breathing through your mouth, and most of the time, it’s because something’s blocking your nose. So your body switches to mouth breathing to make sure you’re still getting enough oxygen. Some common causes include:

  • Nasal congestion
  • Allergies or colds
  • Nasal polyps
  • Deviated septum
  • Trying to stop snoring
  • Tonsillitis, and
  • Colds or flu

Basically, if your nose is blocked, your body will try to find another way to breathe, and your mouth is the next best option. It’s good to keep in mind that, in some cases, consistently resorting to breathing through the mouth may continue even after the root cause has been addressed.

Are There Risks to Breathing Through Your Mouth?

Breathing through your mouth can actually make you more prone to certain health problems:

  • Allergies
  • Asthma or allergic rhinitis
  • Chronic sinusitis
  • Colds or flu
  • Chronic tonsillitis
  • Periodontal disease like receding gums
  • Dry mouth
  • Ear, nose, and throat infections

Is Mouth Breathing Bad for You?

Thing is, breathing through your mouth raises your risk of getting sick more often. It can also dry out your mouth, which leads to bad breath. Long-term mouth breathing can cause more serious problems, too.

Let’s just say the nose is like your body’s natural air filter and humidifier. It preps the air before it hits your lungs, which is a pretty big deal. When you breathe through your mouth, you’re basically skipping that step, which can lead to some issues.

How to Treat Mouth Breathing?

The way you deal with mouth breathing really depends on what’s causing it in the first place. Once you figure that out, things usually get better. It is always worth consulting with your health provider who may have solutions that will be best suited for you or your children. Here are some things you might try:

  • Use nasal decongestants to help clear up congestion, especially during travel
  • Use whatever medications your doctor prescribed if you’re struggling with allergies
  • Sleeping on your side, and raising your head, can help open up your nasal passages
  • Keep your home clean to avoid irritants that might cause congestion
  • Try breathing exercises to help you breathe through your nose more easily

Pay attention to your body and your kids too, and if you notice any signs of mouth breathing get it checked out to treat it ASAP.

Importance of Nose Breathing

You might not think about it much, but your nose is pretty important! When you’re congested, you really notice. It plays a big role in how well your body gets oxygen. Plus, if you’ve got congestion, you definitely notice, right? You might not be getting enough oxygen, and that can mess with how you feel day to day. So, yeah, nose breathing? It’s kind of a big deal for keeping you feeling good and on top of your game.

Your nose makes nitric oxide which helps to improve the lungs ability to absorb oxygen. Nitric oxide also helps increase oxygen circulation in the body. It even fights viruses bacteria and infections and protects your body by supporting the immune system.

Here are some benefits of breathing through your nose:

  • Nose breathing filters the air before it gets to your body
  • The nose adds moisture to the air so the lungs are protected from irritants
  • The nose heats the air before it gets to the lungs.

Key takeaways

  • Mouth breathing, especially if chronic, can increase the risk of infections and oral health problems.
  • Nose breathing provides natural filtration, humidification, and warming of air before it reaches the lungs, leading to better oxygen absorption.
  • Addressing underlying causes like allergies or nasal congestion is crucial in treating and preventing mouth breathing.

FAQ, Myth & Facts

Is mouth breathing normal?

While it can happen to anyone, breathing through your mouth isn’t the ideal way to take in air all the time. It’s more of a backup system when your nose is blocked. If it’s happening a lot, it’s worth figuring out why and seeing if you can switch back to nose breathing.

Can mouth breathing cause dental problems?

Absolutely. Mouth breathing can dry out your mouth, which allows bacteria to thrive. This can lead to cavities, gum disease, and other dental issues.

Is there any way to improve nasal breathing?

Yes! Try using a humidifier, nasal saline rinses, or decongestants when needed. Addressing allergies and correcting any structural issues in your nose can also make a big difference.

Myth: Mouth breathing is only a problem for kids.

Not true! While it can affect children’s development, mouth breathing can cause issues for adults too, like sleep disturbances, dry mouth, and increased risk of infections.

Fact: Mouth taping can help encourage nasal breathing.

Some people have found that using a special tape to keep their mouths closed during sleep encourages them to breathe through their nose instead. However, it’s essential to talk to a doctor before trying this.

For years, I struggled with chronic dry mouth and frequent sore throats. It wasn’t until my dentist pointed out I was likely breathing through my mouth at night that things clicked. Now I focus on nasal breathing exercises and it has helped.

As a parent, I was concerned about my child’s constant mouth breathing, especially at night. We visited an ENT specialist and found out that their adenoids were enlarged. After addressing that, their sleep improved dramatically.

I never realized how important nasal breathing was until I experienced nasal congestion due to allergies. Switching to nasal breathing techniques really made a difference. I have much more energy now.

Thinking about all this mouth breathing stuff, it makes me wonder how often I’m actually doing it without realizing! I guess it’s a good reminder to pay attention to how we’re breathing and make sure we’re giving our bodies the best chance to get that good ol’ oxygen.
