Foot reflexology is based on nerve zones or reflex points that go from the bottom of our feet to the top of our head, encompassing all the vital organs along the way. A reflexologist can put pressure on different meridians or energy lines on the sole and side of the feet to determine the cause of illness. Foot reflexology is good for stimulating internal organs and improving blood and lymph circulation. It can also help alleviate headaches, asthma, tension, constipation, and sinusitis.
