If you’re skeptical when your child tells you that playing a game on a
smartphone or messing around on a tablet is an aid to falling asleep,
you now have a scientific study to back up your naysaying.
“Small amounts of light at night, such as the light from screens, can be enough to affect sleep patterns,” says Mary Carskadon, the study’s senior author and a professor of psychiatry and human behavior at Brown’s Warren Alpert Medical School. “Students who have tablets or TVs or computers—even an ‘old-school’ flashlight under the covers to read—are pushing their circadian clocks to a later timing. This makes it harder to go to sleep and wake up at times early the next morning for school.”
