Screen-Free Family Evenings: Why a Story Beats a Screen Before Bed
The problem with a screen before bed isn't just the content — it's the light. Here's what the research shows, and what to do instead.
There's a physiological reason a story settles a child and a tablet winds them up. Screens emit short-wavelength 'blue' light in exactly the range the brain uses to set its internal clock. Exposure in the evening suppresses melatonin, the hormone that signals sleep.
What the research found
In a 2015 study in the Proceedings of the National Academy of Sciences, Chang and colleagues found that reading on a light-emitting e-reader before bed — compared with reading a printed book — suppressed melatonin, delayed the body clock by over an hour, and left readers less alert the next morning. The American Academy of Pediatrics advises keeping screens out of the bedroom and avoiding screen exposure in the hour before sleep, favouring quiet activities like reading instead.
Screen-free wind-down ideas
- A printed or read-aloud story — the classic for good reason (no blue light, plenty of calm).
- A gentle 'high–low' chat about the best and hardest part of the day.
- Quiet drawing or colouring.
- A short stretch or 'sleepy breathing' together.
- Listening to a story read aloud with the screen off and the lights low.
That last one is worth noting: audio narration lets a child enjoy a story with the lights off and no screen at all — the calming benefits of a story without the sleep-disrupting light.
Frequently asked questions
Why is screen time before bed bad for sleep?
Screens emit blue-range light that suppresses melatonin, the hormone that signals sleep. A 2015 PNAS study found reading on a light-emitting device before bed delayed the body clock by over an hour compared with a printed book.
Is listening to an audio story before bed okay?
Audio avoids the blue-light problem entirely — the child can listen with the screen off and lights low. It offers the calming benefits of a story without the sleep-disrupting light of a display.
How long before bed should screens go off?
The American Academy of Pediatrics suggests avoiding screens for at least an hour before sleep and keeping them out of the bedroom.

You don't need flashcards or apps to raise a reader. The research points to something simpler: read aloud, every day, and make it something your child looks forward to.
Everyday conversation is wonderful — but it recycles the same few hundred words. Books reach for rarer ones, and that's exactly where new vocabulary comes from.
Reading is one of the few activities that supports language, thinking and emotional development all at once — and the evidence for the language part is especially strong.
