The invention is a wrist worn Photoplethysmography Sensor (“PPG”) and Pulsed Electro Magnetic Field (“PEMF”) integrated into a thin ergonomic wristband. The invention will measure heart rate, oxygen saturation, and heart rate variability. In addition to PPG measurements, the PEMF generator treats a users blood with an electromagnetic field tailored to the individual. The electromagnetic field washes red blood cells and/or erythrocytes and/or any other vertebrate organisms which principal means of delivering oxygen and other cellular nutrients to the body tissues via blood flow through the circulatory system for optimal CELLHEALTH™.
