Physical stress and exposure to Ultraviolet (UV) Rays also elevates the positive ion levels within the body. Research shows that excessive positive ion levels are associated with fatigue, lack of concentration, muscle and joint aches, and feeling of nausea. Trion:Z’s minus-ion properties counteract the positive ions created by modern technology, daily stress, and physical activity.Trion:Z Dual Loop Magnetic/Ion Bracelets feature: •Made with “Stayers,” a unique textile with minus-ion producing minerals woven into the fabric •Generates significant, beneficial levels of minus Ions •Produces twenty to fifty times more minus ions than competing ion bracelets •Medical grade magnets in a unique patent Alternating North-South Polarity Orientation maximize magnetic field flow •Penetrates deeper into tissue fibers and muscle •Can be washed and will still maintain its minus-ion producing properties when wet •Can be worn while swimming or surfing
