How we measured 38,114 nights.
A consumer sleep ring, a two-line morning diary and a 31-question survey, asked twice. Here is exactly what we did, who we missed, and how to use the data yourself.
Five things to know before you quote a number.
Rings are good at when you sleep and how often you wake. They are less sure about sleep stages, so we report stages only as shares of a night.
Every volunteer wore the same consumer sleep ring on the index finger for 27 consecutive nights between 13 January and 30 March 2026. The ring estimates sleep onset, wake-ups and stages from movement, heart rate and skin temperature. We counted a night when the ring recorded at least three hours in bed.
1,812 people applied through partner clinics, universities and employers; 1,412 completed at least 20 nights. Night-shift workers and new parents are over-represented on purpose. People without a smartphone, and anyone under 18, could not take part, so the report says nothing about them.
31 questions, asked in week one and again in week four: bedtime habits, screens, caffeine, work hours, how rested people felt and what they believed about their own sleep. The survey vs ring comparison uses the week-one answers.
Rings were registered to a random ID, never to a name. Diaries were written in the same app and stripped of place names. The published dataset rounds bedtimes to five minutes and ages to the year. The six diarists in this report agreed to be quoted and chose their own pseudonyms.
