For a period of five years, I have made it a rule to dress in January exactly as in July--except in the matter of an overcoat. I go without underclothing, I wear no waistcoat, (vest). I do not take exception to the wearing by others of such garments, during the winter months. But for myself, as I gradually learned to take advantage of systematic breathing exercises and thus to charge my blood abundantly with oxygen, the necessity for much clothing disappeared. Underwear grew to be uncomfortable. I found myself both happier and healthier without it. When I wore the heavier clothing in winter, I suffered from frequent colds. Now I am rarely troubled in that manner. If, through carelessness, I do catch cold, I am able easily to throw it off within twenty-four hours by means of extra practice in deep breathing, together with a short fast. I do not wish to infer that the heavier clothing is the cause of colds. My point is, rather, that the extra amount of oxygen I take into my blood supplies the place of the garments formerly worn by me, as well as acts in consuming, or burning up, the poisonous material that gathers in the tissues, and tends to make you _feel_ cold. Let me repeat that I do not advise anyone to experiment with the wearing of summer apparel in winter until after several months of systematic breathing exercises, with the consequent enriching of the blood. The matter, like that of the cold bath, is one for individual discrimination. In my own case, the lighter garb has become actually a necessity for comfort’s sake. Why We Should Establish Schools To Teach The New Science of Breathing Whatever the different systems for muscular and health development may be, the value of developing those vital inner organs--the heart, the lungs and the digestive organs, is easily understood. A large arm, or a wonderful leg development cannot help these inner organs, if they are naturally weak, or if they have been weakened. The point is--what _will_ give health to these organs the fundamental or motor power to all health.
