- "Our results suggest a detrimental effect of screen time and mobile phone-related awakenings on sleep problems and related health symptoms. However, the results should be interpreted cautiously with respect to adolescents’ natural changes in circadian rhythm, which may coincidence with an increase in mobile phone and media use."

- It may not be light color, but light intensity that is really driving the effect. Contrary to common beliefs, it is yellow rather than blue colors that have the strongest effect on the mammalian circadian system.Joshua W. Mouland, Franck Martial, Alex Watson, Robert J.
