Light Drives Our Cellular Clocks

Photoreceptors in skin and nervous tissue send light data to control the body's circadian clocks.
Light is the primary influencer of these cellular clocks that regulate genes, hormones, and repair.

Mitochondria Respond To Red Light

Red and near‑infrared light interact with mitochondrial cytochrome C oxidase to increase ATP production.
This frees nitric oxide, improves oxygen access, and enhances cellular repair and reduced oxidative stress.

Light, Quantum Effects, And Biology

Light interactions occur at quantum levels, making human biology responsive in complex, poorly understood ways.
We emit infrared light ourselves and exist as light-influenced beings in a fluctuating quantum field.
