Biological Enlightenment

Human biology is absolutely dependent on natural light.

Light helps regulate brain chemistry and circadian rhythms that control appetite, energy, mood, sleep, libido, and other body-mind functions.



Light helps us to stay alert and to be productive, as well as helps us to sleep, heal and regenerate.

  • Humans are photobiotic ‘solar beings’ — absolutely dependent on the absorption of vital solar radiation.
  • We are human photocells whose ultimate biological nutrient is sunlight.


We can now say emphatically that the function of our entire metabolism is dependent on light.

Every metabolic process, every enzyme reaction, muscular movements, the digestion of food, and the burning of fat are all biological processes that are augmented by sunlight energy.

A reduction of ‘natural light energy’ causes a slowdown in these processes that leads to decreased metabolism, reduced burning of fat, reduced vitality, and compromised immunity.


Photosynthesis in Plants — Metabolism in Humans

  • The human body functions much like a green plant, collecting energy from the atmosphere.
  • The nervous system may be described as a network of electrical wires which conduct photons of light energy.
  • Light energy is collected by the skin and eyes; converted into photocurrent and channeled throughout the body.
  • Photo-current (voltage) is distributed by nerves and fascia (the fibrous connective tissue found throughout the body) that act as an electrical wiring system.
  • In addition to activating sight in the visual cortex, photo-current travels to the brain’s control center, the hypothalamus.
  • Informed by photo-current, the hypothalamus helps regulate brain chemistry, essential hormones, and circadian rhythms.

Light Energy is Life Energy!



The current science of photobiology, the study of the effects of light on living organisms can be traced to ancient cultures through their use of color and light for healing.

More recently, light (therapy) for healing and health was in vogue until the discovery of penicillin and the world of pharmaceuticals. As a matter of fact, Niels Ryberg Finsen, a physician and scientist of Icelandic descent was awarded the Nobel Prize in Medicine and Physiology in 1903 in recognition of his contribution to the treatment of diseases with concentrated light radiation.


Today light for health and disease prevention is again being rediscovered as a natural prevention intervention.

Every day, more people become interested in the potential benefits of light and dark and its effects on human health and well-being. Lighting characteristics that are effective to the circadian system are different than those effective to the visual system.

Biological rhythms that repeat approximately every 24 hours are called circadian rhythms. Light is the main stimulus that helps the circadian clock, and thus circadian rhythms, keep a synchronized rhythm with the 24-hour solar day.


Humans need to be exposed to a sufficient amount and quality of light for the biological clock to remain synchronized with the solar day.

If a lack of synchrony or circadian disruption occurs, we may experience decrements in physiological functions, neurobehavioral performance, and sleep.

Good temporal entrainment allows for optimal performance at the right time of the day because being able to anticipate future tasks allows the appropriate physiological and psychological preparation. However, our modern society often imposes deviations from the natural light-dark cycle which results in problems with entrainment.

Failure to adapt to environmental and societal time cues (being out of rhythm with nature) leads to misalignment of internal biological clocks. This disentrainment comes with an enhanced risk of errors, accidents, low productivity, and health risks such as the increased risk for cancer, depression, sleep disturbances, gastrointestinal, metabolic and cardiovascular disorders, decreased immune responses, and even life span.

The fact that so many are literally in the dark about light’s vital relationship with health is a cause of serious concern and the cornerstone of our non-profit mission to raise awareness of mal-illumination.

Mal-illumination is brought about by limiting our daily intake of balanced, full-spectrum daylight and supplementing it with too much artificial ‘limited-spectrum’ indoor light.

Mal-illumination silently contributes to many health issues, some quite serious —obesity, depression, fatigue, sleep, and eating disorders as well as breast, prostate, and colon cancer.

Like malnutrition, mal-illumination causes deficiencies by depriving us of the sun’s energetic nutrient wavelengths referred to as photo-nutrition.
