Counterbalance with morning light
Pair the evening sunset with bright morning light to keep the clock anchored.
Why it works
Dimming at night is only half of clock alignment; bright light in the morning advances the clock and reinforces a strong day–night contrast. The two together — bright early, dim late — entrain the rhythm far more effectively than evening changes alone.
How to do it
- Get bright (ideally outdoor) light within an hour or two of waking.
- Treat morning light and the evening digital sunset as one paired routine.
- Keep both roughly consistent so the clock gets a stable daily signal.
Evidence
Morning bright light advancing circadian phase and improving alertness is well established in chronobiology and used clinically in light therapy. (rct)
Exact dose varies with season and individual sensitivity; the direction of effect is reliable, the precise minutes are not.

Common mistake
Obsessing over the evening sunset while waking to dim indoor light, leaving the clock without its strongest daily anchor.

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.
- Curb stimulating content before bed
Cut the arousing, attention-grabbing content, not just the screen brightness.
- 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.
