Massage has very much the same effects upon the system as the cold-water treatment. It accelerates the circulation, draws the blood into the surface, relaxes and opens the pores of the skin, promotes the elimination of morbid matter and increases and stimulates the electromagnetic energies in the body.
We have learned that one of the primary causes of chronic disease is the accumulation of waste matter and systemic poisons in the tissues of the body. These morbid encumbrances clog the capillaries, thus obstructing the circulation and interfering with or preventing the normal activity of the organs of elimination, especially the skin.
The deep-going massage, the squeezing, kneading, rolling and stroking, actually squeezes the stagnant blood and the morbid accumulations out of the tissues into the venous circulation, speeds the venous blood, charged with waste products and poisons, on its way to the lungs and enables the arterial blood with its freight of oxygen and nourishing elements to flow more freely into the less-obstructed tissues and organs.
Through manipulation of the fleshy tissues, the blood is drawn to the surface of the body and in that way the elimination of morbid matter through the relaxed and opened pores of the skin is greatly facilitated.
Very important are the electromagnetic effects of good massage upon the system. The positive magnetism of the operator will stir up and intensify the latent electromagnetic energies in the body of the patient, very much like a piece of iron or steel is magnetized by rubbing it with a horseshoe magnet. The more normal and positive, morally and mentally as well as physically, the operator, the more marked will be the good effects of the treatment upon the weak and negative patient.
