The human body absorbs positive ions from electronic equipment, cell phones, electrical wiring, and machinery encountered in everyday modern life. 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.
