In this light, mention should be made that exercises to develop the chest and to in- crease its capacity for oxygen are well advised. Modern life generally does not adequate- ly develop the musculature and framework of the chest, and it is for this reason that the modern man or woman’s breathing reserve is small compared to that of wild animals and those people of more primitive societies. Regarding our breathing apparatus, the normal nose permits adequate amounts of air to enter the lungs through but one nostril under ordinary conditions. When under great stress, as when running, the additional nostril should provide for the ingress of sufficient air, providing both nostrils are normal. Gen- erally, mouth breathing is a symptom of disease, as in adenoids, polyps, nasal catarrh, a cold, etc. Every day we should take advantage of the cleanest air available in the particu- lar vicinity in which we live. It is important that we do some exercises that will promote greater oxygen intake. This will also enable us to throw out additional poisons from our lungs and help to keep our breathing functions in a healthier condition.

Are specific deep breathing exercises recommended for greater intake of oxygen?

The need for adequate ventilation during sleep was discussed, and the need for outdoor exercise was highlighted. Lesson 13 also explained why passive deep breathing “exercises” should not be indulged but vigorous exercise should be ob- tained. Suggestions were made on how to avoid the harmful effects of artificial lighting and on how to obtain adequate sunlight during the cold winter months of the temperate zones.

Most important for the preservation of health and vitality are sunlight and air. They are just as necessary for growth and perpetuation of life as are liquid and solid food. “When the sun does not enter, thy physician enters,” says an old proverb. It has been found that the greatest mortality occurs in the narrow streets of cities and in houses having northern exposure. The inhabitants of southern mountain slopes are stronger and healthier than those living on the northern sides. Inhabitants of secluded valleys where the sun rises late and sets early are generally afflicted with peculiar diseases, chiefly due to a lack of direct sunlight and its salutary power to dissipate and decompose noxious vapors that accumulate in dark and low places.
