Why Screens Should Be Removed Before Bedtime

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

Quick answer

Screens emit blue light that can disrupt melatonin production, making it harder to fall asleep. Alternatives to screen time before bed include reading books, taking a bath, or quiet play, which help signal the body to prepare for sleep.
