Nationwide sleep extension program for adults who sleep too little

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The study tests a manually determined, self-correcting sleep-extension intervention that is individually tailored and uses Fitbit data plus daily sleep diaries to guide changes. Eligible participants are adults 18–60 who typically sleep ≤6 hours per night, have bedtimes between 8 PM and 1 AM and wake times between 5 AM and 10 AM, and who own a Fitbit with heart-rate monitoring. The intervention adapts to each person’s schedule and does not rely on knowing an individual’s exact sleep need, and outcomes are measured with actigraphy and sleep diaries to capture sleep duration and efficiency. Participants with untreated insomnia or sleep apnea are excluded, and initial sleep efficiency must be at least 85% to enter the program.
