Nose Breathing
© 1997, 2005 Austin "Ozzie" Gontang, Ph.D.
Breathing through the nose on the inhalation:
1. Warms the air
2. Moisturizes the air
3. Purifies the air
When the nose smells some pleasing aroma, the nostrils flair. Look in the mirror and as you breathe in flair the nostrils. Many people when breathing in through the nose, allow the nostrils to be sucked semi-closed by the pressure of the inhalation. Practice the nostril flair so that there is no sniffling sound on the in breath.
The brain is not playing any tricks. The brain that will die without oxygen within minutes, is not playing. The brain (which as most of us know is an integral part of our being) is afraid of dying. So when it is not getting what it considers sufficient nourishment of O2, it will every and any orifice to get enough air to survive and get back to its comfort level.
When one is having difficulty getting air, the body may and often goes into a panic mode. In that mode, the breathing cycle is reversed That is on the inhalation the stomach muscles contract and relax on the exhalation. That is the reverse of inhalation/abdominals relax/diaphragm contract and exhalation/abdominals contract/diaphragm relax. Often the stitch is due to the diaphragm working against the muscles that should be relaxing on the inhalation.
The art of nose breathing takes running slower at first until the mind knows that it is not being suffocated by nose breathing. During a run nose breathe when running slower so as to keep the mind relaxed. At first it may only be 50 to 100 yards. By gradual practice, I know several people, one who has done a 3:17 through the nose and another a half in a sub 90. Both started from the fear of not getting enough air. They practiced and played with it.
Wonder what the world records for nose breathing at all the various distances are?
In an article I wrote for the San Diego Track Club back in the early 80's I wrote about the Mescalero Apaches who trained their kids to run 5 or 6 miles with a mouth full of water. When the crossed the finish line after 5 or 6 miles of running they had to spit the mouthful of water out.
Everyone then was focusing on the great effort not to swallow the water and the great amount of self-discipline demonstrated by these children. I took it the next step beyond the holding water in your mouth for "x" miles. To do so, one could only breathe through their nose.
I mentioned also that one soccer coach got his kids to hold a mouthful of water as they played, saying that they wouldn't have to stop for a drink of water so often. The kids enjoyed the suggestion as they played soccer.
For me the issue was not the water in the mouth, the issue was: "with water in the mouth, one has to nose breathe.
And so I began several years of playing and practicing nose breathing. My fastest through the nose marathon was a 3:27. That was breathing in and out through the nose. Jerry Goldberg another friend who I got to play with nose breathing did an 84:04 half marathon through the nose. As Jerry said to me a few months ago, there are some things you don't forget.
A related article you may find interesting. It is probably more than you wanted to know or even think about...let alone practice. Oz

A Dialogue on Breathing: Some science to aid in what we often know intuitively.
C.2001 Austin "Ozzie" Gontang, Ph.D., Patrick Aro, and Andrew Heiz
Thanks to Andrew and Patrick for creating the opporutnity to gain a better understanding and some scientific information about the role of nasal breathing:
Ozzie Gontang made an assumptive statement wrote:
Breathing through the nose on the inhalation:

2. Moisturizes the air
3. Purifies the air
Andrew rightfully queried:
Please explain all the scientific facts behind these statements!
Patrick responded from the text on Body Structures and Functions:
"Protruding into the nasal cavity are three turbinate, or nasal conchae bones. These three scroll-like bones (superior, middle, and inferior concha) divide the large nasal cavity in three narrow passageways. The turbinates increase the surface area of the nasal cavity causing turbulence in the flowing air. This causes the air to move in various directions before exiting the nasal cavity. As it moves through the nasal cavity, air is being filtered of dust and dirt particles by the mucous membranes lining the conchal and nasal cavity. The air is also moistened by the mucus and by blood vessels which supply the nasal cavity ... by the time air reaches the lungs, it has been warmed, moistened, and filtered." (Scott and Fong, Body Structures and Functions 9th ed., 1997)
Andrew continued his query
How can you say that nose breathing moisturizes the air? Again the argument can be made that since there is more saliva in your mouth than snot in your nose the air coming in through your mouth is in contact with more moisture.
But beyond either of these arguments what is the role of moisturizing air in exercise breathing. And how much moisturization is necessary?

Abstract: "The role of the nose and lower airways in respiration is examined. The nose can increase the temperature of inspired air by as much as 25(degree)C between external nares and nasopharynx; this is because of
the nose's rich blood supply with plentiful arteriovenous anastomoses. The lower airways are poor at warming and humidifying air in comparison with the nose, and bronchoconstriction may result from the temporary development of hyperosmolarity in their walls..."

Title: Comparison of maximal oxygen consumption with oral and nasal breathing.
Source: Aust J Sci Med Sport (AUSTRALIAN JOURNAL OF SCIENCE AND MEDICINE IN SPORT) 1995 Sep; 27 (3): 51-5 Journal Code: B9S
Abstract: " The major cause of exercise-induced asthma (EIA) is thought to be the drying and cooling of the airways during the 'conditioning' of the inspired air. Nasal breathing increases the respiratory system's ability to warm and humidi
fy the inspired air compared to oral breathing and reduces the drying and cooling effects of
the increased ventilation during exercise. This will reduce the severity of EIA provoked by a given intensity and duration of exercise. The purpose of the study was to determine the exercise intensity (%VO2 max) at which healthy subjects, free from respiratory disease, could perform while breathing through the nose-only and to compare this with mouth-only and mouth plus nose breathing."
This study found only a 3% difference in tidal volume (the volume of air inhaled and exhaled in one cycle) between nasal only and mouth only breathing during exercise. Average tidal volume is about 500 ml, so the difference works out to be about 15 ml. Since the residual volume, the amount of air that cannot be voluntarily expelled from the lungs, is about 1500 ml allowing continuous exchange of gasses between breaths, the 15 ml difference seems to be physiologically insignificant. Granted, the study did not research the ability or inability of an athlete to reach peak performance while nasal only breathing, however, it strongly suggests that there are benefits to nasal only or a combination of nasal and mouth breathing.
Andrew finally adds:
And the fact of the matter is there comes a point that breathing in through the nose is not enough. So sooner or later the mouth is going to have the last word (excuse the pun). Or if it doesn't then performance will be at a reduced rate.
Patrick concludes:
Yes, I agree. There is a level of exertion that seems to call for additional or alternative routes of inhalation. However, the study above demonstrated that a recreational runner can achieve and sustain the "fat burning zone" by nose only breathing. ExcUSE the pun? I'd much rather USE one.
As others have suggested and you have already done, experiment with it. If it doesn't work for you, well that's just one more piece of knowledge gained.
Sorry for droning.
Peace as Well,
Patrick
Ozzie adds:
Thank you Andrew and Patrick for a lovely and informative dialogue where we all learned a great deal about breathing through the nose and mouth, the benefits of nasal breathing, and the power and the spirit of collegiality when it comes to educating ourselves.
As Andrew and Patrick have shown so well, don't assume anything. Even the best of science when more information and research are done has been proved to be incorrect because we didn't know what we know now. So Science, from the Latin meaning knowledge, keeps on growing. And with it the amazing aquisitive and inquisitive minds of rec.running.
Rec.running while containing some great info has also been overrun by trolls.
In health and on the run,
