In the 20th century, three medical doctors discovered the existence of invisible maps of the human body on the feet, hands, and outer ears that correspond to specific parts and regions of the body. They found that applying finger pressure to reflex points on these maps stimulates nerve endings and meridian pathways that send messages to the corresponding organs, body systems, skeletal structures, or general body regions (or body zones).

These reflexes amount to functional circuits of nerve pathways or meridian lines that connect the map points with targeted regions in the body. As such, they offer the unique potential for affecting internal bodily functions by the application of special pressure techniques on the skin. It is also believed that these circuits can become blocked and that one of the benefits of reflexology is to relieve the blockage and congestion of energy along these pathways.

Foot Reflexology is practiced worldwide and is the best-known type of reflexology. However, Hand Reflexology is getting increased attention, and integrating both of these with the stimulation of ear reflex regions is gaining more and more acclaim as possibly the most effective form of reflexology.
