May Is Sunshine Month—And Your Biology Feels It
Sunlight Is a Foundational Biological Need— “Sunlight is more than a source of brightness or warmth; it is a key environmental signal that helps regulate
Light entering the eyes regulates brain chemistry and synchronizes vital circadian rhythms that control… Appetite, Energy, Mood, Sleep, Libido and so much more.
Science of Light (SOL) is a 501(c)(3) non-profit organization dedicated to the legacy of photobiology pioneer, Dr. John Ott, the father of full-spectrum light technology.
SOL’s Mission:
To enlighten humanity of the essential need for daily light hygiene to support wellness & reduce the risk of — mal-illumination.
SOL’s Mandate:
Share freely our years of research and provide the lighting technology that mitigates the indoor epidemic of mal-illumination.
“We are all light deficient and this deficiency may be the source of our physical and emotional problems.” — Dr. John Ott, Health and Light, 3,000,000+ copies sold
Science of Light has developed Nutritional Light Technology… the “fullest” spectrum light source.
SOL’s technology builds on Dr. Ott’s original full-spectrum light technology by intrinsically improving the spectral quality and biological benefits that help ignite metabolism and regulates brain chemistry & circadian rhythms that control appetite, energy, mood, sleep, libido and so much more.
