The liberation of electromagnetic currents through cold-water applications has other very important effects upon the system besides that of stimulation. Electricity splits up molecules of water into hydrogen, oxygen and ozone. We have an example of this in the thunderstorm. The powerful electric discharges which we call lightning separate or split the watery vapors in the air into these elements. It is the increase of oxygen and ozone in the air that purifies and sweetens the atmosphere after the storm. In acute as well as in chronic disease, large amounts of oxygen and ozone are required to burn up the morbid materials and to purify the system. Certain combinations of these elements are among the most powerful antiseptics and germicides. Likewise, the electric currents produced by cold packs, ablutions and other cold-water applications split up the molecules of water in the tissues of the body into their component parts. In this way large amounts of oxygen and ozone are liberated, and these elements assist to a considerable extent in the oxidation and neutralization of waste materials and disease products. The following experiment proves that sudden changes in temperature create electric currents in metals: When two cylinders of dissimilar metals are welded together, and one of the metals is suddenly chilled or heated, electric currents are produced which will continue to flow until both metals are at the same temperature. Another application of this principle is furnished by the oxydonor. If both poles of this little instrument are exposed to the same temperature, there is no manifestation of electricity; but if one of the poles be attached to the warm body and the other immersed in cold water or exposed to cold air, the liberation of electromagnetic currents begins at once. These electric currents set free oxygen and ozone, which in their turn support the oxidation and neutralization of systemic poisons. According to my experience, however, the cold-water applications are more effective in this respect than the oxydonor. The Importance of Right Mental and Emotional Attitude in Acute Disease We have learned that in the processes of inflammation a battle is going on between the healing forces of the body, the phagocytes and natural antitoxins on the one hand and the disease taints, germs, bacilli, etc., on the other hand. This battle is real in every respect, as real as a combat between armies of living soldiers. In this conflict, going on in all acute inflammatory diseases, mind plays the same role as the commander of an army. The great general needs courage, equanimity and presence of mind most in the stress of battle. So the mind, the commander of the vast armies of cells battling in acute disease for the health of the body, must have absolute faith in the superiority of Nature's healing forces.
