It’s no secret that screen time before bed can interfere with sleep, especially in younger people. However, a new study reveals that the lighting in the room itself can make a difference. Phone and tablet use in a dark room has a much more pronounced effect on sleep than when the lights are on.
The study, which was conducted by researchers in London and Switzerland, included 6,616 participants between the ages of 11 and 12. The tweens were asked to report on their screen use within an hour of bedtime, stating whether they used their devices, how well-lit the room was, and if it interfered with their ability to sleep. The study included all types of screens, from mobile devices to gaming consoles and televisions.
