Reflexology is the thousands-of-years-old practice of massaging acupressure points in the Feet or Hands to relieve stress/illness/pain, and stimulate mental, emotional, physical healing and well-being in all body systems.
It builds stress resistance + rejuvenates by stimulating meridians, circulation, nerve systems: flushing/detoxing.
HOW IT WORKS:
Each area of the Foot, Hand, Eye (+face, ear) connects via nerves = electromagnetic energy (chi) channels ("meridians") to a particular body organ/system. Rubbing stimulates, flushes that area.
These meridians also run thru our 7 main life energy centers called "chakras" (Sanskrit, "sha-kras") linked to our 7 main endocrine glands, supplying physical, mental, and emotional energy there. Each chakra/gland area also correlates with the 7 rainbow color.
Area Tenderness=illness or calcium/waste deposits from preservatives, caffein, alcohol, cigarettes, other toxins + mucle acid (from tension or no exercise) in that area.
