Your Brain Runs on Light

  • by

It’s been said that the body is the temple of the soul. It houses the spirit. And just like a house, the body has a plumbing system and an electrical system.

One could equate the body’s plumbing system with food and nutrition that’s ingested. Most nutritionists, dietitians and health gurus are focused soley on the body’s plumbing system when they speak of the importance of a healthy, balanced diet.

Curiously, most health professionals are completely in the dark about the nutritional value of light aka “photo nutrition” that’s delivered primarily through the eyes directly to the brain and distributed by the body’s “electrical” nervous system.

Light entering the eyes converts to “photo current” in the body.

The brain has two distinct pathways that process light. One is the visual system that consciously processes illumination and color from the environment. The other is something we’re less conscious of. In 2002, researchers discovered retinal cells that detect light but are not involved in vision.

In addition to the visual system, photo current also regulates brain chemistry and circadian rhythms via a tiny region of the brain called the suprachiasmatic nucleus (SCN) which acts as the master clock of your body regulating your daily rhythms of sleep, wakefulness, and other functions. The SCN is located in the hypothalamus. The hypothalamus is often referred to as “the brain’s brain” because it controls many vital processes such as hormone secretion, body temperature, and appetite.

Circadian rhythms control every process in the human body.

Because this second pathway is beneath our conscious perception, it’s hard for individuals to gauge how light is changing their sleep-wake cycle, moods, and overall health… however, the effects can be profound. 

Common lighting is not designed with nutrition in mind.

“We have finally learned that light is a nutrient much like food, and like food, the wrong kind can make us ill and the right kind helps keep us well.” —Dr. John Ott

Experience uncommon light that’s loaded with near infrared light.

“One third of the energy your body consumes comes from the food you eat. The vast majority of the energy your body needs to maintain systemic equilibrium comes from environmental infrared light exposure.” — Dr. Alexander Wunsch, MD, PhD
