Set your phone to alarm-only mode after 9pm
After 9pm, your phone should be capable of receiving calls only — everything else silenced.
Key takeaways
- What it is: After 9pm, your phone should be capable of receiving calls only — everything else silenced.
- Why it works: Late-evening notifications are a form of variable-ratio intermittent reinforcement: occasionally rewarding enough to keep the checking habit alive at night. Alarm-only mode removes the reward schedule and tells the nervous system there is nothing to check — producing a gradual extinction of the late-night checking compulsion over one to two weeks.
- Evidence: Plausible mechanism, limited direct outcome data.
- Avoid: Enabling Do Not Disturb but making exceptions for too many apps, so the mode becomes indistinguishable from normal mode.
Why it works
Late-evening notifications are a form of variable-ratio intermittent reinforcement: occasionally rewarding enough to keep the checking habit alive at night. Alarm-only mode removes the reward schedule and tells the nervous system there is nothing to check — producing a gradual extinction of the late-night checking compulsion over one to two weeks.
How to do it
- 1Enable Focus or Do Not Disturb with exceptions only for calls from starred contacts.
- 2Set this to activate automatically at 9pm daily — manual activation fails because of the urge-to-check problem it is trying to solve.
- 3Do not check whether you received any messages until morning.
- 4Inform close contacts about your policy so genuine emergencies can reach you.
What the evidence says
MechanisticVariable-ratio reinforcement schedules maintain compulsive behavior; removing the schedule reliably produces extinction. Scheduled Do Not Disturb modes have been shown in observational studies to reduce late-night phone use and improve sleep outcomes.
Honest caveat: Extinction of phone-checking habits takes 1-3 weeks and may involve a brief extinction burst (increased urge before it fades); this is normal and not a reason to abandon the practice.
Common mistake
Enabling Do Not Disturb but making exceptions for too many apps, so the mode becomes indistinguishable from normal mode.
