"Light is essential for all life on earth. It’s fundamental to human health, and light is a key component of a balanced lifestyle, just like diet, exercise, and sleep. But light is often overlooked as a major contributor to health and well-being. And most people don’t get nearly enough sunlight: the average American spends over 90% of their time indoors, surrounded by bright artificial light."

"Each of the above spectrums of sunlight is crucial for optimal health, controlling everything from our sleep/wake schedule, mood, hormones, our production of vitamin D, and cellular energy!
The easiest way to envision how natural light affects our health is by segregating each effect into the spectrum of light needed to produce it.”

"Additionally, visible light can penetrate the full thickness of the skin and induce pigmentation and erythema. Clinically, lasers and light devices are used to treat skin conditions by utilizing specific wavelengths and treatment parameters. Red and blue light from LEDs and intense pulsed light (IPL) have been studied as anti-microbial and anti-inflammatory treatments for acne. Pulsed dye lasers are used to treat vascular lesions in adults and infants. Further research is necessary to determine the functional significance of visible light on skin health and wellness without confounding the influence of ultraviolet and infrared wavelengths."
