Study Finds Devices Emitting More Sleep-Disrupting Blue Light.

reports that a study published in Frontiers in Public Health and led by Prof. Paul Gringras of Evelina Children’s Hospital in London, found that newer electronic devices are more likely to disrupt sleep because of their brighter and bluer displays. Prof. Gringras said that “smartphones, tablets and e-readers should have an automatic ‘bedtime mode’ that stops them disrupting people’s sleep.” He said that the devices emit “blue light that delays the body clock and keeps people awake later into the evening.” He explained that there are “some sleep-aware apps” that “reduce blue-green light emissions,” and that the devices could have a “bedtime mode” that would “filter out the blue” light. http://www.bbc.com/news/health-34744859
