Sleep latency benchmark
How long should you take to fall asleep?
The healthy adult range sits at 5–15 minutes. Falling asleep in under 5 minutes is not "great sleep" — it's the threshold that clinical multiple sleep latency tests use to flag pathological sleepiness. Falling asleep above 30 minutes consistently is one of the criteria used to define chronic insomnia.
Your latency band
Healthy
This is the band associated with adequately rested, healthy adults. You're falling asleep at a rate the literature treats as normal.
Suggested next steps
- Keep your current schedule.
- Re-check if anything changes — illness, schedule disruption, caffeine increase.
Where the bands come from
The 5-minute cut-off comes from the Multiple Sleep Latency Test (Carskadon & Dement, 1982): mean sleep onset under 5 minutes across daytime nap opportunities is the standard threshold for pathological sleepiness. The 30-minute threshold for insomnia is from the AASM research diagnostic criteria (Edinger et al., 2004), paired with frequency (≥ 3 nights/week) and duration (≥ 3 months).
One number on one night doesn't diagnose anything. Track over 1–2 weeks and look at the pattern alongside efficiency and total duration.
