The Silent Epidemic

Mal-illumination is brought about by limiting our daily intake of ‘full-spectrum’ daylight and supplementing it with too much artificial ‘limited-spectrum’ indoor light, especially at night, and by shielding ourselves from the sun with such things as tinted windows, windshields, sunglasses and suntan lotions.



Now more than ever in this Age of Information, millions of people are starving for the sun’s life energy and unwittingly suffering from Mal-illumination… the silent epidemic.

Circadian Rhythms

All humans are synchronised to the rhythmic light-dark changes that occur on a daily basis. Rhythms in physiological and biochemical processes and behavioural patterns persist in the absence of all external 24-hour signals from the physical environment, with a period that is close to 24 hours. These rhythms are referred to as ‘circadian’, from the Latin ‘circa diem’ (‘about a day’), and are attributable to internal biological clocks, driven by a major circadian pacemaker in the brain. The circadian pacemaker is entrained each day to the 24-hour solar cycle, which is the major ´zeitgeber´ (literally time-giver). Other zeitgebers are food intake, activity, or social cues, e.g. the alarm clock.

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 enhanced risk of errors and accidents, loss of productivity, and health risks such as increased propensity for cancer, depression, sleep disturbances, gastrointestinal, metabolic and cardiovascular disorders, reduced immune responses and even decreased life span.
How it Works

Radiant Health

Since the beginning of human history people have lived, worked and played outdoors during the light of day, active and vibrant, absorbing the full spectrum of light energy photons from the sky. An average of 10 hours each day, 70 hours weekly, was common for eons. But in less than a mere two hundred years, millions of people have unwittingly become “contemporary cave dwellers” living and working indoors. This dramatic reduction of natural light exposure, and its’ domino-effect disturbance to vital ‘light regulated’ circadian rhythms, was coined “mal-illumination” by the late Dr. John Ott, the father of full-spectrum light.



Mankind’s radical shift indoors, away from nature’s ‘health regulating’ solar energy that our genes are programmed to respond to, leave us with a decreased immune response… and even life span.


Our Mission
  • To inform and educate the entire world about Mal-illumination and the need for natural light in our daily lives and wellness programs.
  • To share freely our many years of research into the biological effects of light on human health & behavior.
  • To provide the necessary technology for the eradication of Mal-illumination.

Light is to mal-illumination as food is to malnutrition
