The underlying theory behind reflexology is that there are certain points or "reflex areas" on the feet and hands that are connected energetically to specific organs and body parts through energy channels in the body. By applying pressure to reflex areas, a reflexologist is said to remove energy blockages and promote health in the related body area. Here are some examples of reflex areas and their corresponding body parts: The tips of the toes reflect the head; The heart and chest are around the ball of the foot; The liver, pancreas, and kidney are in the arch of the foot; Low back and intestines are towards the heel.
