There's nothing quite like a foot rub, especially after a hard day's work and a long commute home. It's sure to be even more pleasurable if the person working on your feet is a trained practitioner of reflexology, a holistic therapy currently enjoying a boom throughout Japan. Reflexology is an easy way to relieve stress and, arguably, receive other therapeutic benefits, which has no doubt contributed to its popularity -- you can pop into a local salon, take off your shoes, and be out the door in less than 30 minutes, feeling relaxed, refreshed and invigorated.

The human foot, which contains 26 bones and 33 different joints, was once described by Leonardo da Vinci as "a masterpiece of engineering and a work of art." Each foot contains more than 7,000 nerve endings, which connect via the spinal cord and brain to all areas of the anatomy. This is the basis of the practice of reflexology, which uses specific pressure points on the feet to relieve problems elsewhere in the body.

According to reflexology practitioners, the foot is divided into a number of reflex zones, which correspond to different parts of the anatomy. For example, the toes represent the head, including the teeth, mouth, nose, brain, eyes and ears, and the ball of the foot represents the chest area, including the lungs and heart. In essence, the feet are a mirror of the body. Through application of pressure (using the thumbs, index finger and even the knuckles) on these reflexes, reflexology is believed to relieve tension and promote the natural function of the related areas of the body. According to Opal Knowles, president of the Reflexology Association of America, "Reflexology works with all the body's systems to improve the function of the entire system, including organs, glands, and circulation."
