The Quantlet’s light module utilizes several frequencies of visible and near-infrared (NIR) light to non-invasively irradiate the blood circulating through your wrist. The effects of light on reducing pain, inflammation and edema, have been known for almost forty years.
Photobiomodulation, as it is known scientifically, has demonstrated increased exercise capacity and longer exercise times, as well as improved biomarkers (including reduced lactate, creatine kinase, and CRP) after exercise in people treated with red and infrared light. It has also been reported to release certain brain compounds that positively affect mood and sleep.
At the cellular level, specific frequencies of light have been shown to stimulate cells in blood to generate more energy and utilize oxygen more effectively.
Within certain blood-based cells exist components called mitochondria, which produce cellular energy in the form of adenosine triphosphate (ATP). An enzyme in mitochondria known as cytochrome c-oxidase (CCO) utilizes light photons and converts them into ATP. This process also creates mild oxidants (ROS) that lead to both cellular repair, healing and gene transcription. Nitric oxide that has bound to the CCO is also released, enabling enhanced oxygen uptake and helping blood vessels dilate; thereby improving blood flow.
The Quantlet’s cooling module utilizes a thermoelectric cooler (TEC) that leverage the Peltier effect. By using a solid-state cooling mechanism to cool your blood while irradiating the placement site with the appropriate light frequencies, the Quantlet stimulates vasodilation through the localized release of nitric oxide (NO).
Both physical and mental functions are impaired when your body’s core temperature increases such as when you perform strenuous exercise. Physical performance can be enhanced with the aid of body cooling.
The Quantlet addresses the two primary steps involved in cooling the body: convection through blood flowing through the wrist and conduction from blood vessels through the skin of the wrist.
