Artificial Light from Tech Devices May Impair Sleep Cycles

Maybe there’s a reason why students and profs seem more tired than in the past. From Education Week:

That's because evidence is mounting that use of artificial light from energy-efficient lamps and computer and mobile-electronics screens later and later in the day can lead to significant sleep problems for adults and, particularly, children.

While lights and electronic devices that mimic daylight can improve students' attention and alertness if used during normal daytime hours, Dr. Charles A.
