Curb stimulating content before bed
Cut the arousing, attention-grabbing content, not just the screen brightness.
Why it works
A large part of how screens hurt sleep is psychological, not photonic: news, social media, work email, and gripping shows raise emotional and cognitive arousal, which competes directly with the down-regulation sleep requires. Engaging content also pulls you to keep going, displacing the hours you meant to sleep.
How to do it
- Set a cutoff for activating content — news, work, social feeds, intense shows.
- Shift the last stretch to genuinely calming, low-stakes activities.
- If you use a screen late, choose something that winds you down, not up.
Evidence
Pre-sleep arousal is a recognized barrier to sleep onset, and engaging media is associated with later bedtimes and poorer sleep — driven substantially by arousal and time displacement, not only light. (observational)
Much of this is correlational; it points to content and timing as real levers alongside light, not at a single proven dose.

Common mistake
Dimming the screen but doom-scrolling the news in bed — solving for light while leaving the arousal and displacement untouched.

More practices for The Digital Sunset
- Dim your evening light
Lower overall light intensity at night — the lever that actually moves your clock.
- Don’t over-rely on blue-light glasses
Treat blue-light-blocking glasses as a weak, optional add-on, not the fix.
- Set a screen cutoff time
Pick a consistent hour to put screens away and protect the wind-down window.
- Keep screens out of the bedroom
Reserve the bed for sleep so the space itself cues winding down.
- Counterbalance with morning light
Pair the evening sunset with bright morning light to keep the clock anchored.
