The science of light & sleep
Scientific breakthroughs in circadian biology have shed light on the systems that
govern our sleep cycles. It should be no surprise that it all starts with the sun.
The sun is rich in blue light that signals “daytime” to our brains, setting off a cascade
of physiological responses that keep us awake and alert.

We now spend
90% of our time indoors
Today, we are surrounded by artificial light sources, and long after the sun has set, we continue to bombard our eyes with LEDs that emit the same “wake-up” wavelengths of blue light found in the sun. This comes at a great cost to our
sleep and performance.

How much is too much blue?

is too much blue?
At night, any light source emitting greater than 2% blue light will start to disrupt sleep.
Standard LEDs emit from 10-30% blue light.

Wavelengths matter
Blue light in the Critical Circadian Wavelength (CCW) range (440-495nm) signals “daytime” to your circadian system and tells your
body to suppress the natural production of melatonin (sleep-friendly hormone), keeping you awake and alert.

How our eyes digest light
Our eyes interpret light with three types of cells. Rods help us see shadow, light and motion. Cones allow us to see color.
ipRGCs signal our circadian system, informing pineal melatonin and cortisol production, sleep regulation systems, cognitive
function, alertness, body temperature, mood, and emotion.
