Nationwide sleep extension program for adults who sleep too little

Hypknowledge Nationwide Sleep Extension

This program will try a personalized, Fitbit-supported sleep-extension approach to see if adults who usually sleep 6 hours or less can get more nightly sleep and improve related outcomes.

Quick facts

• Phase: Not applicable
• Study type: Interventional
• Enrollment: 1038 (estimated)
• Ages: 18 Years to 60 Years

• Locations: 1 site (Tucson, Arizona)
• Trial ID: NCT07345767 on ClinicalTrials.gov

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.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18–60 who typically sleep ≤6 hours per night, own a Fitbit with heart-rate monitoring, have bedtimes between 8 PM and 1 AM and wake times between 5 AM and 10 AM, do not have untreated insomnia or sleep apnea, and show baseline sleep efficiency ≥85%.

Not a fit: People who sleep more than 6 hours per night, lack a Fitbit with heart-rate monitoring, have untreated insomnia or sleep apnea, have bed or wake times outside the required windows, or have low baseline sleep efficiency are unlikely to benefit from this program.

Why it matters

Potential benefit: If successful, the approach could help short sleepers increase nightly sleep duration and reduce health risks linked to chronically insufficient sleep.

How similar studies have performed: Preliminary and pilot work suggests tailored, device-supported interventions can increase sleep duration in short sleepers, but there are currently no widely validated, large-scale interventions for insufficient sleep.

Eligibility criteria

Inclusion Criteria:

7. Must not have sleep apnea as determined by diagnosis or STOP-BANG scale, or must be treated.
8. Must have a computer or smartphone device for daily sleep diaries.
9. Must have an initial sleep efficiency of at least 85% as determined by sleep diaries and actigraphy.

Exclusion Criteria:
