Screen time before bedtime could be especially damaging to preteens

Bad for kids: Screen time before bed has become pervasive and a new study suggests it could be particularly detrimental for children and young teens.

Experts have been warning for the last few years that mobile device and computer screens diminish sleep quality, but a new study suggests the effect could be particularly detrimental for children and young teenagers. 

Nighttime light exposure of any kind can imperil sleep, yet the new study says that pubescent boys and girls between the ages of nine and 15 are particularly sensitive – more so than older teens.
