Reflexology is a non-intrusive complementary health therapy involving the applying of gentle pressure to the feet. This therapy is based on the theory that different areas on the feet are linked to different parts of the body.
The ancient Chinese have documented reflexology as a treatment for certain afflictions. It involves the reflexologist applying pressure to specific areas in the feet that affect certain reflex areas of the body. 
There is a connection between zones of your feet that represent certain areas of your body that can be adjusted or managed through these reflex areas. A lot of the theory behind reflexology has to do with aligning your qi, to support stress, anxiety, induce sleep and relaxation.
