A few years back when I started running again after the Military, a buddy suggested I hold water in my mouth. It forced me to breath thru my nose. It was simple but it really worked.

I always was told to breathe in through the nose, and out through the mouth.

[@ropersix]

I do that sometimes, and think it tricks your brain a little bit, and makes it easier to breathe through your nose, versus just closing your mouth.

[@Original50]

When I was a runner and started to lose comfortable breathing, I would slow the breath-cycle down; inhale over 4 paces, exhale over 4 paces. Very calming and part of my ' zone'.

🎯 Key Takeaways for quick navigation: 00:00 🏃‍♀️ If you constantly feel out of breath while running, you may be going too fast or there may be something wrong with your approach to workouts. 01:30 💨 Breathlessness is not primarily caused by a lack of oxygen but by a lack of carbon dioxide in the body. 02:55 🩸 Carbon dioxide buildup in the body triggers the release of oxygen from hemoglobin, which fuels our muscles. 04:34 🌬️ Over-breathing, or excessively inhaling, causes low carbon dioxide levels in the body, making us more sensitive to its presence and leading to breathlessness. 06:24 💯 The Body Oxygen Level Test, developed by Patrick McKeown, can measure your tolerance for carbon dioxide and determine if you are over-breathing. 09:21 🌬️ The normal adult who exercises moderately should be able to hold their breath for 20 seconds, while athletes should aim for 40 seconds. 10:31 🚩 A breath hold of less than 20 seconds indicates a significant need for improvement in breathing and endurance. 10:44 🏃‍♀️ Adjusting your breathing patterns can make you a better, stronger, and more comfortable runner and athlete. 11:10 📚 Gradually decrease breathing volume and increase carbon dioxide tolerance to improve performance. 11:37 👃Breathe less through the mouth and more through the nose to limit oxygen intake and allow for natural carbon dioxide buildup. 12:17 📲 Download the free Quick Start Program in the app to practice nose breathing for running. 12:47 👍 Check out the Oxygen Advantage resources and KZbin channel for more information on breathing mechanics and patterns.

Your results on this test can vary greatly depending upon when it is done. On a rest day, it can be very high. On a day after a workout, run, etc, it can be very low. This test is used by some to determine if overtraining is a problem. It is usually done by loading up first: a series of three max inhales and exhales, and then hold. If you determine that you can hold for 40 seconds max, and then on a particular day you can only do 20, this means that you aren’t fully metabolically recovered from previous activity.

[@imdrunkwithoutbeer]

Yeah started off having to tap out at 20. Repeated this clip maybe 10 more time and maybe 12 minutes after the first test I could get to 38 seconds.

[@dinogerc318]

I do high intensity workouts. Today we on Mondays we have legs day and there are stairs 5 sets of them each has about 21 steps. We run and down with different intensity and step widths. 1 by 1, 2 by 2, 3 by 3. Full speed slow, squatts in between. And then every time we get on top we run same same as football field also at different speeds and intensity. I did this test basically 6 hours after the workout and I did 1 minute 5 seconds. Im not in great shape nor in shape. I was a professional soccer player in last century, lol

I never tried this test before and I’m not athletic or anything, but I was able to do 47 seconds without any effort, and i felt like I could go for longer.. so this explains it. I think since I don’t work out my body doesn’t need as much oxygen.. not sure about how useful this test is

[@zevkej]

Interesting, Ive been steadily increasing my runs for the last 30 days since getting back into it and i did 5 miles previous run it felt great, I didnt feel fully recovered and I could barely do a mile without feeling extremely fatigued. I guess i should have waited a bit longer to go for another run. It was 3 days between.

[@Gus-hb8bi]

I've always taken my breaths through my nose and have always been "criticized" for doing this, despite not having any issues with it. Usually once every couple minutes I will take a large breath in during my run and I find that I'm balanced as well as more comfortable. I tried following the "in through the nose, out through the mouth" gig and it actually caused me to collapse during a run because I got too lightheaded. Thanks for your awesome channel! I'll be back to watch more soon.

[@sarelito9202]

I can relate to this, and found it motivating. Now I can do 22 seconds slightly uncomfortably, but when I was fit I could do 40 without particular effort. I used to do the Tibetan square or box breathing which helped a lot. You are supposed not to force how long you hold your breath or lack of breath at the beginning, simply even out the 4 phases, so if you start with a short inhale, the exhale must be kept to the same length, and you repeat the set in the same way, then when you start again you just follow whaat happens spontaneously on the inhale and so on. In time, the hold time both in and out gets longer and the breathing easier.

[@bobjones6756]

Hey does that sincerely work?

[@deltavictor290]

@@bobjones6756 try it and see, I use this while I run and it works well for me. When you exhale rest the tongue on the floor of the mouth and force the air out while using the muscles of the abdomen to pull your navel to your spine. The inhale then just happens as a response to the relaxing of the abdomen, places the tip of your tongue behind your upper front teeth and pull the air in through the nostrils as that allows the most flow into the lungs. Think of your body as a running machine and do the counts in your head until it becomes natural for you. Good luck and let me know if it works well for you. Cheers!

Great video! Really drove home some points for me. I got 38 sec on the test btw. I'll say one thing that you got wrong, tho. In Mr James Nestor's book, Breath, he states that you actually intake 30% more oxygen thru your nose than you do the mouth even if it doesn't feel like it. I've been trying to incorporate strictly nasal breathing while running which is easier in less humid weather. Takes a lot of work but I was able to run 2 miles with uphill just with my nose working on a clear day.

In my country, school sports activities are called "Physical Education". This involves giving children a ball and forgetting they exist for 45 minutes. When it comes to the one-kilometer race for evaluation, some of the children don't even finish. I had the same experience. I got bad grades in running and the teacher never explained to me or the other kids what the problem was. Thanks to this film, I have a lot of useful information and a path for further research.

After your 37 seconds how long did it take to catch your breath? It should have been instant in 1 breath. If it takes more, you held your breath for too long I think.

I’m in the same boat. I have asthma and got covid twice, but I made it to 30 seconds comfortably and 35 without a spasm. Yet, I cannot run without an inhaler.

Nice work! Everyone's doing great on this test :)

[@beccakreidler8290]

I come from swimming where nose breathing is critical to keep water out, etc. Also, it has to be synchronized with breath intake in swimming. You use your nose to push out air as you inhale through your mouth in the sidemouth technique. As a result, it's actually massively difficult for me to not breathe through my nose. In order for my ENT to evaluate my mouth breathing, I have to pinch close my nose. But I am one of 2 people in the literature with damage to my nose muscle. I have velopharyngeal disfunction as a result of who knows. One of the issues I have with my diagnosis was it is such a rare issue. Your nose muscles are small and are not explicitly used to conscious control. I worry about overtraining. In fact, I would bet that some sort of overtraining led to my initial injury. Like VCD/ELIO, my velopharyngeal disfunction has specific triggers: cold definitely, altitude maybe? (still trying to analyze it), allergies or sinal congestion definitely. It's great to work on your breathing but these are all relatively small muscles that as smooth muscles are not going to "bulk up". Likewise, the tendons that connect your various respiratory tract muscles to your skeleton don't have a toughening up period. So Coach Nate, I would encourage you to bring a speech/language pathologist into your breathing work, particularly as you are training other people in the techniques. They really are experts on this muscle pathway. I would also discourage people with any pre-existing conditions from overtraining. Do not do breathing work with active sinus infection conditions. Do not overtrain on breathing if you have a physical blockage or other biological damage, in the same way we wouldn't tell you to run on a broken ankle. Get cleared by an ENT or a Speech/Lang Pathologist if you have a physical barrier to nose breathing. Having damaged my nose muscles, it has completely re-routed what I can do. My nose will collapse into my airway if I overtrain. I can't breathe in daily life. I have to sleep on my face. It eventually resolves itself but it can take up to 3 weeks to fix itself. Sprinting and other hard breathing exertions are triggers/cause failure. Cold air can cause a failure. Exercising while dehydrated can cause failure. Exercising with heavy allergy flow can cause failure. It's a rough way to live when I come from 15 years of swimming and another 15 years of team sports. It took out peak bagging for me. We are just understanding ELIO/VCD and other associated respiratory track damages. We need to move in this space carefully because there is a lot we don't know on a scientific level.

[@mikelara2345]

Great info! Thanks for sharing. Remember that other health conditions can affect our oxygen levels. I had adrenal fatigue killing my energy levels. It took a long time to figure out what was happening and how to help myself.

[@TomEatsNC]

What did you do to get help?

[@matthewtikka5133]

@@TomEatsNC with some simple at home tests I found that I was dealing with adrenal fatigue. This was caused by a chronic fight or flight response created from a life time of abuse. There are several ways to correct this, one of my favorites is using the mammalian dive reflex. By holding your face under cold water, your body will force itself into a responce to survive a swim. This will lower our oxygen consumption, lower anxiety, decrease the heart rate and blood pressure, among other things. All mammals have this involuntary responce to water on the face. You don't need to hold your face in the water till your gasping for breath, but long enough to feel the need for breath. Repeat submerging your face while holding your breath untill you feel a shift. For me, my stomach usually growls, this lets me know that my digestive system just engaged. Your body is not designed to digest and stress at the same time. It's kinda one or the other. If I'm really stressed I will feel a sence of calm hit me when my stomach growls. People very widely with how well they transition depending on their individual conditions. Don't be surprised if you feel extremely exhausted shortly after. It also may be short lived and then I dunk my face again to reset to calm. A super hard nap is a good sign. Hope this helps

[@TomEatsNC]

@@matthewtikka5133 thanks for the info. I'll give it a try. What did you do to heal the adrenals fatigue? Did you self diagnose? I'm in the same boat but idk where to seek help.

[@matthewtikka5133]

@@TomEatsNC for me it was self diagnosed, then confirmed by a doctor. One easy self test is with your eyes. Within your nervous system, the system that regulates the adrenal glands is the same system that regulates pupil dilation. Go into a dark room with a flash light and give yourself at least 30 seconds for your eyes to adjust to the low light. Facing a mirror hold the flashlight pointing toward your face but not directly at it. Kinda like that classic campfire scene where the flashlight is at chest level shining across your face. Make sure the light hits your eyes. Count the seconds that you pupils stay contracted. If you make it to 30 seconds adrenal fatigue may not be an issue. On the other hand, the shorter the time your pupils are contracted, the more fatigue your adrenals are. For myself, it appears as if the flashlight is flickering on really bad days. My pupils can't hold for more than 3 seconds and they keep recontacting and then letting go. It can happen rapidly. As far as treatment, I have found it's more of a mindset/lifestyle change than anything. Doctors can help, but really all that needs to happen is the body needs to rest. Avoid stimulation like caffeine for a while. Get some proper sleep. Meditation can be extremely beneficial. Lots of people get stuck in what is referred to as beta brain waves, this is good for being productive at work but not good for resting. Meditation can help to learn how to step down into alpha waves and hopefully theta waves. Theta is where the really good spot for healing happens. During this time do whatever you can to let the body and the mind know you are safe. The water on the face trick I mentioned will help. I have found natural things like kava and St John's wart to help as well. Find things that work for you and stick with it for a while. Also, as difficult as it is for some people, cutting down on screen time will help as well. This is a learned thing so don't get discouraged if it seems impossible at first, or it feels as if nothing sticks. Depending on how chronic your condition is, you may only hold the relaxed state for seconds at a time to begin with. But with practice those seconds will grow to minutes and eventually hours and days. Hope this helps

Actually here because I'm not having issues with being out of breath, so I'm wondering what I might have done correctly. And the video just fully confirms it. After years of no running at all, I started running in June this year in the middle of a heat wave at high noon. Along with having a narrator coach me through keeping my pace under control, I also challenged myself to avoid breathing through the mouth (avoiding both inhaling and exhaling) because I heard it just gets you more efficient. I still found myself having to make a big exhale through the mouth once or twice every 10 minutes, and when I did, I definitely noticed the tingling, leaving me feeling rejuvenated to push on the run further.

The way I always thought of it was, when you breathe in through the nose you cause a higher vacuum or pressure difference in your lungs drawing on the capillaries and making the smaller molecule, CO2, leach out more readily and when you breath out through your mouth or nose you cause a slightly higher pressure pushing the oxygen into the capillaries.

When holding my breath, I feel fine at first, then there is that window where you feel your body naturally cry out to breathe. If you can power through that window, you reach a point where it ends and you can calmly hold your breath without the panicked need to breathe.

Also.... maybe I'm wrong but isn't he saying it backwards? He's suggesting that we need a higher concentration of carbon dioxide in our bloodstream to regulate our labored breathing? But no... High CO2 levels cause that feeling of suffocating. So you need to focus on your exhale to push CO2 out of your lungs and LOWER your CO2 bloodstream concentration - not raise it up higher.

[@colinmartin9797]

I'm a paramedic with a degree in biochemistry and biomolecular analysis and this was a pretty fair explanation of the process. Two small mentions though - if you can hold your breath for quite a while but feel really out of breath during exercise, see with your doctor if you might have exercise induced asthma. EIA is a surprisingly common condition, and forcing exercise without treating the asthma can actually cause permanent lung damage without you even knowing it. And second, hemoglobin is pronounced like "globe", like the planet.

[@ixifutureproof9286]

No don't do that! Watch animals. When they're chilling they're breathing through their nose. When they're running they breathe through their mouths, and continue to until they've recovered. Nose breathing isn't about the size of the hole! It's about warming the air which reduces construction of the airways as well as releasing nitric oxide which is a vasodilator (opens up the blood vessels) Win win. Google it. Buteyko discovered it whilst observing respiratory patients sleeping.

I've never heard of the idea of CO2 tolerance before. Funnily enough, as a lifelong asthmatic, i've always struggled with my breathing and have developed a lot of control over my breath, just not much in the way of stamina. The first time I tried the experiment in this video, I managed to push it to 19 seconds. A minute later, I could barely manage 10. I think, after many years of wheezing, my body has become hard wired to try and take in more oxygen. I've had moments in my life where my asthma seems to clear up and I wasn't sure why? Perhaps certain breathing methods i've experimented with, had built up my CO2 tolerance. If I remember correctly, it was breath in through the nose for 3 seconds, breath out through the mouth for as long as you can. I guess it's time to start experimenting again!
