Reflexology involves the application of pressure on the feet with a specific finger, thumb and hand technique. This is an alternative medicine that helps relieve stress, pain and anxiety, improves blood and lymph circulation and stimulates the activity of internal organs. The reflexology therapy which is also called the zone therapy does not involve the use of oil or lotion. It is based on a system of zones and reflex areas that purportedly reflect an image of the body on the feet and hands. Such a therapy affects the body and brings about a physical change. There is no general theory 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 this one can improve health. The body is divided by the reflexologists into ten equal vertical zones, five on the right and five on the left. Such a technique helps in reducing stress and improves one's emotional state.
