A Medical Clinic in Japan has reported great success with the use of infrared treatment for Whiplash, Sciatica, Menopause, Arthritis, Shoulder Stiffness, Rheumatism, Acne, Gastroenteric Problems, Ear Diseases and Insomnia, Muscle Spasms and Tension, Lower Back Pain, Trauma and Repetitive Stress Syndromes, Post-exercise Muscle Pain, Gouty, Rheumatoid Ailments, and the list goes on.
The infrared sauna technology differs from the more familiar saunas that heat the air with steam or rocks. This heat emanates from the light at the far end of the spectrum; it falls between visible rays and microwaves.
For this reason it is often referred to as far infrared sauna therapy. Because it does not overheat the air but, rather, penetrates into skin and muscles, it has been put into use by NASA for its astronauts, and the neonatal units in hospitals keep babies warm with it.
