Anxiety & Stress: The Overlooked Role of Light
Anxiety isn’t always caused by thoughts alone. Very often, it reflects a deeper biological imbalance—one that begins with light. Human physiology evolved under the full
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.

Light Therapy Shows Potential — Bright light exposure can suppress appetite and reduce weight gain by activating a visual pathway that connects directly to the

‘Tis the Season of Depression — For millions of people, fall and winter bring shorter days, reduced sunlight, and a drop in overall mood and energy.

— Indoor LED environments overexpose people to short-wavelength blue light while suppressing the regenerative power of longer wavelengths—a combination unprecedented in nature with measurable consequences

— For centuries, poets, healers, and everyday observers have known what science is only now confirming: sunlight nourishes the brain as much as the body.

Understanding Light and Menopause – Hormone balance starts with the light that enters your eyes each morning. – Bright artificial light at night disrupts that
