The reasoning for this method is because the body takes quite some time to re-absorb its own blood after being placed in targeted areas Therefore, prolonging the benefits. We have selected these magnets to serve to the 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 hood harmonizes bodily functions safely and naturally, stimulating recovery time, promoting blood circulation, increasing oxygen flow, and ultimately reducing pain and stiffness
