Irene Lyon: "A lot of people are hearing blue light's bad, blue light's bad. But that is from the artificial screens that are human-made (man-made, woman-made), that are artificial. But that natural blue light from the sun in the morning, the sunlight, that is of the healthy kind. Correct?
Carrie Bennett: "Correct. Absolutely. So this blue light from the sun tells time in our brain. It's really the color, the wavelength of light that keeps time, because it predictably varies from like nothing at sunrise to increasing intensity till the sun reaches its high point, and decreasing in its intensity until after sunset.
"So that's why when we stare at a screen where the color, the amount of blue is never changing, it's confusing. It's confusing to our circadian rhythm.
"And then imagine at night when we're staring at a screen with this artificial blue light, when at night there should be zero blue light in our environment. Again, it's confusing to the circadian rhythm."
