Build a consistent pre-sleep wind-down routine

Create a repeatable 30-60 minute pre-sleep sequence that cues the nervous system toward rest.

Why it works

The nervous system does not switch from alert to sleep on command — it descends through a gradient of arousal. A consistent pre-sleep sequence functions as a classical conditioning trigger: the same series of cues, repeated nightly, becomes a reliable signal for the parasympathetic shift. The ritual also displaces the screen time that occupies this window by default.

How to do it

1. Design a 30-60 minute sequence that you can do every night: dimmed lights, bath or shower, physical book, light stretching, journaling — whatever reliably relaxes you.
2. Use the same sequence in the same order each night. Consistency is what creates the conditioning.
3. Exclude all screens from the sequence.
4. After four weeks, notice whether the start of the routine triggers a recognisable shift toward sleepiness.

Evidence

Sleep hygiene guidelines consistently recommend pre-sleep routines based on circadian and behavioral conditioning evidence. Consistent sleep scheduling and pre-sleep rituals are among the most reliably effective components of sleep hygiene education. (clinical)

Sleep hygiene as a standalone intervention has modest effect sizes in clinical research; it is most effective as part of a fuller behavioral protocol.

Common mistake

Designing a wind-down routine that is too elaborate to actually do every night, so it becomes aspirational rather than consistent — consistent and modest beats elaborate and intermittent.
