Sleep your way to better blood sugar: study tests personalized sleep extension to prevent diabetes
NCT ID NCT03398902
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tested whether helping people with pre-diabetes get more sleep could improve their blood sugar control and lower their risk of developing type 2 diabetes. Researchers worked with 150 adults who slept less than 6.5 hours per night, giving some a personalized sleep extension plan and others their usual sleep schedule. Over 8 weeks, they tracked blood sugar levels and sleep patterns to see if more sleep made a difference.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Sleep extension (behavioral intervention based on CBTI principles)
- What this could lead to
- If successful, this approach could offer a simple, drug-free way to improve blood sugar control and reduce the risk of developing type 2 diabetes in people with pre-diabetes.
- What could go wrong
- This is a small, early-stage study (150 participants) testing a behavioral change, which can be hard to maintain long-term. Results may not apply to everyone, and the effect on preventing diabetes is not yet proven.
