Core evidence
Psychological detachment after work is strongly linked to better recovery, lower strain, and better next-day functioning. Without detachment, the brain remains in unresolved task mode.
Practical mechanism
Evening rumination is often driven by open loops. A 5-minute closure routine (tomorrow list + one top priority) reduces residual cognitive load.
Digital sunset routine (20 minutes)
T-60 before sleep: stop work email and messaging.
T-30: write tomorrow's top 3 tasks, then close devices.
T-20: slow breathing or screen-free walk.
UX micro-copy
"Disconnecting is not disengagement. It is cognitive maintenance for tomorrow's performance."
Intentional disconnection is a productivity strategy, not a luxury.
