What Is RED Light ?

Red and near-infrared light are part of the electromagnetic spectrum, and more specifically, part of the spectrum of light emitted by the sun (and also fire light). These wavelengths of light are “bioactive” in humans. That means that these types of light literally affect the function of our cells.

Most importantly, you need to grasp that the human body needs light to be healthy.


These are the five types of bioactive light in humans:


1. Blue light – sets the circadian rhythm in our brain, which in turn regulates numerous different neurotransmitters and hormones.
2. UV light – allows us to synthesize vitamin D from the sun.
3. Far-infrared – acts to heat up our cells (this is the part of the sun’s spectrum that you feel as heat) which stimulates. changes in cell function, as well as circulation changes
4. Red light – acts on the mitochondria in our cells to stimulate increased cellular energy (ATP) production.
5. Near-infrared (NIR) – acts on the same pathways as red light – particularly in the mitochondria in our cells to stimulate increased cellular energy (ATP) production.
