2. Thorough elimination of waste.
a. Through the lungs by oxidization. Deep and adequate breathing accomplishes the two ends of eliminating some of the poisonous waste (as carbon dioxide from the lungs) and bringing quantities of oxygen to the internal cells for burning up of waste. Active physical exercise and the habit of deep breathing are both necessary.
b. Through kidneys and intestines. These are Nature’s plumbing system for removing poisonous waste. Regularity in these functions should become a habit in early childhood. There should be a bowel movement once or twice a day. Abundance of laxative foods in the diet, water between meals, outdoor life and activity, are natural means of regulating these functions.
3. Regulation of bodily heat. Colds and chills pave the way for vital disorders. They are not always symptoms of an infection. They are often due to poor training of the nerves in the skin to respond quickly to changes of temperature. The training of these nerves can come only as that of any other nerves—through their exercise. Indoor and sedentary life does not supply sufficient exercise for them; for this exercise there is required:
a. A low slightly variable temperature, 65°-68° F. indoor
b. Perceptible air current
c. Air baths, sun baths, and cold-water baths administered with judgment
