When your cells are properly oxygenated, your heart doesn’t have to work as hard to keep things in circulation. That means that the body can release oxygen with less effort, providing cells with the oxygen they need to operate at maximum efficiency. Therefore, more CO2 is available within the body overall when nasal breathing, whether you’re pushing it hard on a run or sitting on the couch. A Closer Look at The Bohr EffectĪs mentioned above, nitric oxide produced when nasal breathing simultaneously increases carbon dioxide and lowers the ratio of oxygen to carbon dioxide. This phenomenon is known as the Bohr effect. While it sounds counterproductive, this lower breathing rate is crucial to allowing more oxygen to enter the bloodstream. This can be attributed to the lower breath rate that nasal breathing allows. However, respiratory rate, breaths per minute, and the ratio of oxygen to carbon dioxide output all decreased while nasal breathing as opposed to mouth #WorkoutHack? Tape your mouth shut! Yes, we’re serious! 🏋️ #fitness #exercise #airwayhealth #mouthbreathers ♬ original sound - Somnifix Their maximum oxygen intake did not change when comparing nasal breathing and mouth breathing. The participants of this experiment were then tested while both nasal breathing and mouth breathing while running to compare their rates of maximum oxygen intake.Īdditionally, their oxygen and carbon dioxide levels were monitored while they exercised.
Throughout that time, they utilized nasal breathing only while running. That means quick fatigue and unnecessary stress on the body, lungs, and muscles. When you mouth breathe, you’re essentially starving your cells of the proper amount of oxygen they need. Therefore, increased oxygenation is not possible. Mouth breathing, on the other hand, does not produce nitric oxide. When CO2 rises in the blood, oxygen can release. This is all thanks to nitric oxide, a miraculous molecule that helps to increase carbon dioxide (CO2). One of the best benefits of training yourself to breathe through the nose over the mouth when running? It allows for more oxygen to reach active muscles and tissues.
What the Research Says About Nasal Breathing While Running But you might be wondering what science says about whether it’s better to breathe through the nose or mouth when running. This prevents dry mouth and sore throat.īy mouth breathing, you’re building an unconscious habit to go against the method of breathing that nature intended.īy nasal breathing during a run, you can take your fitness to the next level. The small hairs, known as cilia, located within the nostrils remove dirt, debris, germs, and toxins from the air.įurthermore, the nasal passages humidify the oxygen we breathe. The nose also boasts a filtering system, unlike the mouth.
The nose, on the other hand, warms or cools the air as needed.įor that reason, breathing through your nose at all times (especially during a run in hot or cold weather) ensures that the lungs aren’t shocked by extreme temperatures. The lungs have a harder time taking in hot or cold air, which is what happens when we breathe through the mouth. It’s part of our evolution and it helps us survive.īeyond that, our noses also provide temperature control. Our throats are configured to allow us to breathe and suckle at the same time, hence why babies do it. It’s the way we were designed to breathe by default. Newborn babies breathe in and out of their noses. Nasal Breathing vs Mouth Breathingįrom birth, humans breathe through the nose. Is it better to breathe through the nose or mouth when running? The answer can be found right on your face! It’s your nose. However, there is some truth behind the idea that there is a more efficient way to breathe while running. With the rise of biohacking, it seems like there’s a new tip or trick to elevate every activity, especially when it comes to exercise. Finding out which hacks are worth your time and which ones are gimmicks can be challenging. It seems like there’s a hack for everything these days.
