How it Works Far infrared rays are also called vital rays because of its regenerative effects on the body. "Resonant absorption?is the phenomenon of the body reaching its fullest healing response to the external production of far infrared energy. Tissues needing repair selectively absorb the rays while the remaining rays pass on harmlessly.

Wilkins): Collagen tissues increase in extensibility needed for repair & recovery of injuries involving ligaments, joint capsules, tendons, fasciae & synovium; Joint stiffness decrease in thickened connective tissues for greater flexibility and full range of muscular motion; Muscle spasms are relieved with the heating of muscle fibers; Pain is relieved through increased endorphin production & dilation of blood vessels brought about by direct heat application on tissues & nerves; Blood flow is increased by inducing expansion of capillaries promoting quick muscle recovery; Inflammation is arrested           Reported Therapeutic Benefits of Far Infrared Energy Great success has been reported with the use of far infrared treatment for the following:   - Arthritis (TMJ, traumatic, gouty, rheumatoid & DJD) - muscle spasms - lower back pain - adhesions - compression fracture - spinal cord shock - muscle tension - post-exercise muscle pain   - shoulder pain & stiffness - bursitis - whiplash - menopause symptoms - rheumatism - gastro enteric problems - insomnia                   More provocative results have been reported with the use of far infrared treatment for the following:   - cancer of the tongue reversed - burn relief, healing & less scarring - high blood pressure - coronary artery disease - gouty arthritis - low blood pressure - short-term memory - cancer therapy - cerebral hemorrhage - soft tissue injury from auto accident - exposure to toxic electromagnetic fields - acute & chronic arthritis - rheumatoid arthritis - menopause symptoms - arteriosclerosis & hypertension
