Chapter 17:
Nostril Breathing vs. Mouth Breathing.
One of the first lessons in the Yogi Science of Breath, is to learn how to
breathe through the nostrils, and to overcome the common practice of
mouth-breathing.
The breathing mechanism of man is so constructed that he may breathe either
through the mouth or nasal tubes, but it is a matter of vital importance to
him which method he follows, as one brings health and strength and the other
disease and weakness.
It should not be necessary to state to the student that the proper method of
breathing is to take the breath through the nostrils, but alas! the ignorance
among civilized people regarding this simple matter is astounding. We find
people in all walks of life habitually breathing through their mouths, and
allowing their children to follow their horrible and disgusting example.
Many of the diseases to which civilized man is subject are undoubtedly caused
by this common habit of mouth-breathing. Children permitted to breathe in this
way grow up with impaired vitality and weakened constitutions, and in manhood
and womanhood break down and become chronic invalids. The mother of the savage
race does better, being evidently guided by her intuition. She seems to
instinctively recognize that the nostrils are the proper channels for the
conveyal of air to the lungs, and she trains her infant to close its little
lips and breathe through the nose. She tips its head forward when it is
asleep, which attitude closes the lips and makes nostril-breathing imperative.
If our civilized mothers were to adopt the same plan, it would work a great
good for the race.
Many contagious diseases are contracted by the disgusting habit of
mouth-breathing, and many cases of cold and catarrhal affections are also
attributable to the same cause. Many persons who, for the sake of appearances,
keep their mouth closed during the day, persist in mouth-breathing at night
and often contract disease in this way. Carefully conducted scientific
experiments have shown that soldiers and sailors who sleep with their mouths
open are much more liable to contract contagious diseases than those who
breathe properly through the nostrils. An instance is related in which
small-pox became epidemic on a man-of-war in foreign parts, and every death
which resulted was that of some sailor or marine who was a mouth-breather, not
a single nostril-breather succumbing.
The organs of respiration have their only protective apparatus, filter, or
dust-catcher, in the nostrils. When the breath is taken through the mouth,
there is nothing from mouth to lungs to strain the air, or to catch the dust
arid other foreign matter in the air. From mouth to lungs the dirt or impure
substance has a clear track, and the entire respiratory system is unprotected.
And, moreover, such incorrect breathing admits cold air to the organs, thereby
injuring them. Inflammation of the respiratory organs often results from the
inhalation of cold air through the mouth. The man who breathes through the
mouth at night, always awakens with a parched feeling in the mouth and a
dryness in the throat. He is violating one of nature's laws, and is sowing the
seeds of disease.
Once more, remember that the mouth affords no protection to the respiratory
organs, and cold air, dust and impurities and germs readily enter by that
door. On the other hand, the nostrils and nasal passages show evidence of the
careful design of nature in this respect. The nostrils are two narrow,
tortuous channels, containing numerous bristly hairs which serve the purpose
of a filter or sieve to strain the air of its impurities, etc., which are
expelled when the breath is exhaled. Not only do the nostrils serve this
important purpose, but they also perform an important function in warming the
air inhaled. The long narrow winding nostrils are filled with warm mucous
membrane, which coming in contact with the inhaled air warms it so that it can
do no damage to the delicate organs of the throat, or to the lungs.
No animal, excepting man, sleeps with the mouth open or breathes through the
mouth, and in fact it is believed that it is only civilized man who so
perverts nature's functions, as the savage and barbarian races almost
invariably breathe correctly. It is probable that this unnatural habit among
civilized men has been acquired through unnatural methods of living,
enervating luxuries and excessive warmth.
The refining, filtering and straining apparatus of the nostrils renders the
air fit to reach the delicate organs of the throat and the lungs, and the air
is not fit to so reach these organs until it has passed through nature's
refining process. The impurities which are stopped and retained by the sieves
and mucous membrane of the nostrils, are thrown out again by the expelled
breath, in exhalation, and in case they have accumulated too rapidly or have
managed to escape through the sieves and have penetrated forbidden regions,
nature protects us by producing a sneeze which violently ejects the intruder.
The air, when it enters the lungs is as different from the outside air, as is
distilled water different from the water of the cistern. The intricate
purifying organization of the nostrils, arresting and holding the impure
particles in the air, is as important as is the action of the mouth in
stopping cherry stones and fish bones and preventing them from being carried
on to the stomach. Man should no more breathe through his mouth than he would
attempt to take food through his nose.
Another feature of mouth-breathing is that the nasal passages, being thus
comparatively unused, consequently fail to keep themselves clean and clear,
and become clogged up and unclean, and are apt to contract local diseases.
Like abandoned roads that soon become filled with weeds and rubbish, unused
nostrils become filled with impurities and foul matter.
One who habitually breathes through the nostrils is not likely to be troubled
with clogged or stuffy nostrils, but for the benefit of those who have been
more or less addicted to the unnatural mouth-breathing, and who wish to
acquire the natural and rational method, it may perhaps be well to add a few
words regarding the way to keep their nostrils clean and free from impurities.
A favorite Oriental method is to snuff a little water up the nostrils allowing
it to run down the passage into the throat, from thence it may be ejected
through the mouth. Some Hindu Yogis immerse the face in a bowl of water, but
this latter method requires considerable practice, and the first mentioned
method is equally efficacious, and much more easily performed.
Another good plan is to open the window and breathe freely, closing one
nostril with the finger or thumb, sniffing up the air through the open
nostril. Then repeat the process on the other nostril. Repeat several times,
changing nostrils. This method will usually clear the nostrils of
obstructions.
We urge upon the student the necessity of acquiring this method of breathing
if he has it not, and caution him against dismissing this phase of the subject
as unimportant.
