If you remember high school physics, when you pass white light through a prism
it separates out the different colors based on their wavelengths (ROYGBIV). Only
a tiny part of this spectrum (roughly 400nm to 700nm) is actually visible to the
human eye.
What is Red and Near Infrared
Light Therapy?
Below is a chart outlining the electromagnetic spectrum:
LIGHT THERAPY OVERVIEW
Red and near-infrared light are part
of the electromagnetic spectrum,
and more specifically, part of the
spectrum of light emitted by the
sun. These wavelengths of light are
“bioactive” in humans.
