Limiting screen use for one week may improve teenagers' sleep – study

Reducing blue light exposure at night may decrease fatigue and mood swings, researchers find

Sleep problems suffered by teenagers can be improved after just one week by limiting evening exposure to light-emitting screens on mobile phones, tablets and computers, a study suggests.

The research indicates that by reducing their exposure to blue light-emitting devices in the evening, adolescents can improve their sleep quality and reduce symptoms of fatigue, lack of concentration and mood swings after seven days.
