Reflexology, also known as zone therapy, is an alternative medicine involving application of pressure to the feet and hands with specific thumb, finger, and hand techniques without the use of oil or lotion. It is based on a pseudoscientific system of zones and reflex areas that purportedly reflect an image of the body on the feet and hands, with the premise that such work effects a physical change to the body.
There is no consensus among reflexologists on how reflexology is supposed to work; a unifying theme is the idea that areas on the foot correspond to areas of the body, and that by manipulating these one can improve health through one’s qi. Reflexologists divide the body into ten equal vertical zones, five on the right and five on the left.
Reflexologists posit that the blockage of an energy field, invisible life force, or Qi, can prevent healing. Another tenet of reflexology is the belief that practitioners can relieve stress and pain in other parts of the body through the manipulation of the feet. One claimed explanation is that the pressure received in the feet may send signals that ‘balance’ the nervous system or release chemicals such as endorphins that reduce stress and pain. These hypotheses are rejected by the medical community, who cite a lack of scientific evidence and the well-tested germ theory of disease.
Reflexology’s claim to manipulate energy (Qi) is unsupported by science; there is no scientific evidence for the existence of life energy (Qi), ‘energy balance’, ‘crystalline structures,’ or ‘pathways’ in the body.
