In 2012, the American Medical Association’s Council on Science and Public Health made this announcement: “Exposure to excessive light at night, including extended use of various electronic media, can disrupt sleep or exacerbate sleep disorders, especially in children and adolescents. This effect can be minimized by using dim red lighting in the nighttime bedroom environment.”

“The amount of blue light in the spectrum of light sources increases with increasing color temperature. So far a number of studies have investigated the effects of the color temperature of lighting on mental activity, the central nervous system and alertness. These studies have demonstrated that higher color temperatures (7500 K versus 3000 K) are more activating from the viewpoint of mental activity level. Both the parasympathetic and sympathetic nervous systems are thought to be enhanced under higher color temperature conditions and drowsiness has been observed to be higher under lower color temperature lighting when comparing 3000 K with 5000 K .” -
