Why is it better to breathe through your nose than your mouth?

Straight off I will say that this is not a yoga thing. I hate yoga, and I am allowed to hate it. Does that make me a terrorist?

There are many reasons why it is better to breathe through your nose than through your mouth. And this is going to be an interesting one!

I don’t know what got me thinking about this, but after I did, I stumbled on a video that I found fascinating. Who knew that something we think of as so simple could have several entire books written about it, not to mention a 2-hour video?

And by the way–as weird as it may seem–it is two hours of steady, crucial information. Here is a link to the video, and I will add it again near the end.

We Were Designed to Breathe Through Our Nose

Babies breathe through their noses. How else would they be able to suckle and breathe at the same time?

We were designed to breathe through our nose, rather than our mouth for several reasons. Maybe most importantly, our nose filters out undesirable stuff in the air, like dust and bugs and debris. If anything does get through when nose-breathing, it will tend to go directly down your throat, rather than into your lungs.

Another maybe obvious benefit to nose-breathing is that when breathing through your nose, you can smell if there is something dangerous in the air, or if something in your food has exceeded its shelf life. As well, your nasal passage is a humidifier (moisturizing the sinuses) and an air-temperature regulator.

But there is so much more to it than this!Why Is it Better to Breathe Through Your Nose Than Your Mouth

Do You Have Trouble with Breathing Through the Nose?

If you have trouble with breathing through the nose, there is probably something you can do to help. And you should strongly consider doing whatever you can to make nose-breathing possible, because breathing through your nose rather than your mouth has great benefits. If you are not a nose-breather, I would bet you have some troubles.

Here is a page that lists 7 tips to breathe better through your nose.

Negative Effects of Mouth Breathing

The negative effects of mouth breathing include snoring, poor sleep, dry mouth, abnormal facial and dental development, poor oxygen concentration in the blood (which can lead to many other health issues), bad breath, gum disease, and much more.

There are surgical methods of improving the ability to nose-breathe, if one is unable, due to a birth defect or other condition.

Leslie Grant, DDS, spokesperson for the Academy of General Dentistry says that, “After surgery and/or orthodontic intervention, many patients show improvement in behavior, energy level, academic performance, peer acceptance and growth. Seeking treatment for mouth breathing can significantly improve quality of life.”

Mouth Breathers Don’t Sleep Well

Sleep disruption occurs in people who tend to mouth-breathe while they sleep.

Dry mouth and other discomforts, due to awkward functioning of things while your mouth is open, and snoring will all result in poor sleep.

We know the effects of poor sleep. If a child is performing poorly in school, or having problems socially, watch how they sleep. A child can be falsely diagnosed with Attention Deficit Disorder or other things, when the only problem they have is brain fog / a poor ability to focus, due to not sleeping well.

Naturally Increase Nitric Oxide

Our nose produces nitric oxide, which aids the lungs in absorbing oxygen.

As well as being an agent which helps oxygen to be transported to the blood, heart and brain and everywhere else in our bodies, nitric oxide does much more. It is crucial for healthy blood vessels. If you eat lots of leafy greens and other vegetables that are commonly known to be generally healthy, you should be okay.

Nitric oxide is also very important for the immune system, fighting fungi, viruses, parasites and bad bacteria.

Here is a great article on nitric oxide, and all of its benefits. It also explains ways to increase nitric oxide levels, and much more.

Achieving Nasal Breathing

Breathing strips can help if you have trouble breathing through your nose during sleep. They may even help you to not snore. But if you just habitually breathe through your mouth and want to stop, its as simple as forming a new habit, which there are aids for, of course.

Some of these products are gimmicky. You don’t need them any more than you need a self-cleaning cordless butt scratcher.

I am thinking of the adhesive mouth strips, which do the exact same thing as a piece of tape. The idea, of course is to hold your mouth shut while you sleep, forcing you to breathe through your nose. Red Green (Sorry, maybe an elusive reference for non-Canadians…) couldn’t make a disaster out of this concept, and would figure this out in about 1 second.

Nose Breathing Techniques

I should mention at this point that while simply breathing through your nose is critical, we also need to breathe through our noses properly. Ready to look at some nose breathing techniques?

Our expert in the video I mentioned at the start, Patrick McKeown (who is a lovely Irish gentleman who is very fun to listen to, by the way) has some methods and nose breathing techniques that amaze. If you have trouble breathing through your nose, he demonstrates a simple exercise that could almost instantly resolve the issue for you.

The fancy tape-over-the-mouth technique can force you into the habit of breathing through your mouth while you sleep. It will also likely help to form a habit of nose-breathing while you are awake.

Whether or not you have issues preventing you from breathing through your nose, whether asleep or awake, there may be simple ways to correct this. Please watch this video before you commit surgery, or buy expensive apparatus that you may not require.

Become Aware of Your Breathing

The main thing, once you have decided that proper breathing is very important to our overall health, is to become aware of your breathing.

The fundamental thing, besides breathing nasally, is developing an awareness of how we breath, and make sure we are breathing deeply and slowly.

If you are like me and getting on in years, time tends to widen you in the middle, disproportionately to the rest of you. That weight restricts your diaphragm, making you naturally tend to breathe more shallow, unless you are aware of it. When you become habitually aware of your breathing, you can also make a habit of breathing deeper and slower. In the two weeks since I have been practicing this, I have noticed how quick and shallow my breathing was. And since I have become more and more aware and adjusted accordingly, I have noticed that I just feel much better. And I’m quite certain I have always been a nose-breather.


If you didn’t know before about why it is better to breathe through your nose than through your mouth, you should now have a clear idea about why it is very important, whether or not you have watched the video I am obviously strongly recommending.

Here it is again, as promised.

We have seen that we were designed to breath a certain way. As everything else with our health and how our bodies are designed, it is best to simply ponder how that design was designed. Only then will we quickly begin to realise that with the design, we were also given a mind that can deduce pretty easily that we have a built in owner’s manual that came with the design of our bodies. It is located in our common sense, which is a very nice gift.

Maybe common sense is not so common anymore, but that is because we have been indoctrinated to believe that doctors and medical “authorities” are Lord.

They are not!

Without breath, we are dead. Think about that.

Proper breathing should not be automatic, and is not, as I have been personally discovering, and as you may be considering also, by now. Once you learn some nose breathing techniques and train yourself to breathe properly, proper breathing will become quite automatic. But if you find yourself with a myriad of physical and mental issues, despite maintaining an otherwise healthy lifestyle, proper breathing should be looked at before rushing off to buy a bunch of ridiculous crap from a pharmacy. Or obediently gliding off to a clinic to be subscribed a bunch of chemicals for things you don’t even have.

I hope you have found some value in this.

Happy Breathing!

  1. Such a wonderful article and informative 2 hour video we’ll worth it. I’m currently pregnant and struggling with sinuses issues. It is currently hard to practice those breathing exercises but I did learn a lot about breathing how to truly help my baby when he comes to the world. Thank you so much.

  2. Diana, I’m so glad you understand. The simplest things evade us as we get older. It doesn’t even have to be complicated. Just be aware of your breathing. It’s not rocket science. 

  3. A baby take deeper breath than an adult, if you watch the movement of their stomach it is obvious. However over time everything changes. Thank you for a very educating article – Why Is it Better to Breathe Through Your Nose Than Your Mouth? The nose filters our oxygen intake and keeps us healthy.

  4. Thank you so much for expounding, Millie! I will likely update this, based on what you have said. I hadn’t considered the taste aspect, but of course!

    Yes, I remember a couple of childhood friends who were mouth breathers, and had all kinds of issues.

  5. I am aware for optimal lung development and maintenance, breathing through our nose is essential!  I had a friend who had severe nasal issues and had no choice but to mostly breathe through her mouth.  She was so limited in doing virtually everything that she did not have a great childhood, nor a healthy life as an adult as she spent more time needing medical attention than enjoying life.

    Another observation I made through my friend was her inability to taste and enjoy her food.  The dots were connected even then that if you cannot breathe properly through your nose, even your own taste buds are not going to function as well as it should.  And, when you think about it, this makes sense.  When experiencing nasal congestion due to a cold or flu, the appetite deteriorates because the ability to enjoy our food like normal simply isn’t there.

    Also, by being able to breathe properly through your nose, did you know this actually helps you digest your food better?  Yeah, it does make a difference!  When nasally congested, not only are you unable to taste your food, but your system won’t be able to digest it properly either.  And, believe it or not, this also contributes towards a person’s weight issues.

  6. Thank you very much, Ian. I very much appreciate it. I am only 51, and finally starting to try to be aware of my breathing, and it is hard to make it a habit, but you can do it. 

    I was wondering why I had a very big surge of traffic yesterday to this article, so now I think I see why. Much thanks!

  7. This is true.
    Your page was very good reading as far as your nasal breathing techniques go once again you should breathe properly.
    As it said please watch the video which I did very good video hope you don’t mind but I transferred the video to my site, as I’m dealing with age and disabilities and I thought yes it could go well within my sight to let the people know about breathing and what it can do.
    Reading this site of yours breathing deeply and slowly seems to take a bit of effort up-to-date before I’ve breathed in trying it for 6 seconds at a time becomes, difficult as I have always been an intermittent breather using both mouth and nose when necessary.
    Very well structured article reason is fine unfortunately didn’t like call jam video much so turn it off halfway through.
    When I got to your conclusion I had to go and watch that breathing video and as I said I transferred it to my site.
    Conclusion I don’t know whether it’s going to be hard for me at 81 years of age to train myself after all these years to breathe correctly but I am sure I will have a go.
    This site of yours very informative and you’re write-up explains to the point of understaning all you write about and why you should breath through your nose.

  8. Hi Craig. Thank you for very interesting article. To be fair I never thought too much how Im breathing and I didn’t know that its so important to make it properly. But looking on your post it was obviously mistake and I will focus more on my breathing awareness. Your advices and recommendations will be very useful and I hope shortly I will  see results of more proper breathing.

  9. First of all, I have a common ground with you: I hate yoga. Enough said. Now concerning breating through the mouth, I learnt to do it during singing lessons because we had to exhale through our mouth in order to sing more clearly. However, I wasn’t aware that breathing through the moiuth could cause many ailments such as poor sleep and even poor dental development (!). I did learn a lot with your article. Thank you!

  10. I didn’t know that nose-breathing was so important. I had already arrived to the conclusion we’re designed to breath with our nose but I had not thought in all the negative effects that breathing with our mouth could bring us. I am glad I came across your post. Now I will head over to the 2-hour video.

  11. Thank you for sharing such an emphasizing article, on the importance of breathing through our noise. The general benefits of doing so are meanly for air filtering. That removes dust and other debris that may cause havock to the human body. The hair follicles found in the nose do most of the trapping of foreign particles which may include pollen, with the help of a moisturized environment and mucus. Unlike breathing through the mouth were all the dust and pollen particles are taken in, which can be dangerous to the human body.
