William Fitzgerald developed the 'zone theory' after finding that he could induce numbness and reduce certain symptoms in the body by simply applying pressure to specific points on the hands and mouth.
The zones are throughout the body with the head having five zones on each side. All the zones lie in each finger and thumb and the theory is that energy travels through the zones and these have an energy connection to all organs, muscles, blood supplies, nerve cells and different tissue types. Disturbances in any of your body will affect these zones so by applying pressure on your hands and feet to these zones it will stimulate the flow of of energy back through your body to the area that needs it.
