Why Screens Should Be Avoided Before Bedtime

A structured overview of what credible sources and parent perspectives commonly say about this topic.

Quick answer

Screens emit blue light that suppresses melatonin, the hormone that signals the body to sleep, making it harder to fall asleep. Alternatives to screen time before bed include calming activities like reading a book, taking a bath, or quiet play.
