The Rejuvenate SmartHood fabric is made up of ceramic nano-particles which emits far-infrared rays keeping muscles supple and relaxed. It features 27 magnets (1100 gauss surface strength) to target key acupressure points on the head, neck, and shoulder areas. In ancient (and current) Chinese medicine, acupuncture is performed by using one's own blood to re-inject over targeted acupuncture points. The reasoning for this method is because the body takes time to re-absorb its own blood after being placed in targeted areas—Therefore, prolonging the benefits. These magnets have been selected to serve to that affect by pulling the blood to those targeted areas which will continually stimulate those areas during and after the SmartHood is worn. Each magnet is enclosed in a soft cushion for enhanced comfort. The SmartHood helps harmonize bodily functions safely and naturally stimulating recovery time, promoting blood circulation, increasing oxygen flow, and ultimately reducing pain and stiffness.See complete Benfab Collection
