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 and 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.
