Light is an essential nutrient of life. Using the sun’s light as therapy dates back thousands of years. Modern science has evolved the engineered delivery of the beneficial wavelengths (colors) of the sun’s light into low level light therapy (LLLT) technology. Polychromatic light therapy is a unique therapy that harnesses the healing powers of infrared light. Unlike normal blue, red or yellow light, near infrared (also known as IR) light is invisible to the human eye. It emits special wavelengths of light energy that dramatically increase circulation to injury sites and areas of chronic pain. The IR light has been reported to dilate blood vessels at the site of treatment. The result tends to be a more rapid relief of discomfort, improvement in sensation, and regeneration of damaged tissues.
