Reflexology is a natural healing art based on the principle that there are reflexes in the feet, hands and ears and zone related areas, which correspond to every part, gland and organ of the body. Through application of pressure on these reflexes with the feet being the primary area of application, reflexology relieves tension, improves circulation and helps promote the natural function of the related areas of the body. Reflexologists believe that the blockage of an energy field, invisible life force, or Qi, can prevent healing. Another tenet of reflexology is the belief that practitioners can relieve stress and pain in other parts of the body through the manipulation of the feet. One claimed explanation is that the pressure received in the feet may send signals that ‘balance’ the nervous system or release chemicals such as endorphins that reduce stress and pain. Reflexology combined with a targeted massage on the neck, shoulders and scalp can aid and provide relief for those suffering from migraines, chronic fatigue, plantar fasciitis and sleep related issues.
