Sleep more, slash diabetes risk? small study tests the idea.

NCT ID NCT06128265

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study looked at whether getting more sleep or keeping a regular bedtime could improve how the body handles sugar and insulin in overweight adults who usually sleep less than 7 hours a night. Eighteen African American men and women aged 21-50 were asked to either extend their time in bed by 2 hours or stick to a consistent bedtime for 24 days. Researchers measured changes in sleep patterns and blood sugar control to see if better sleep could reduce diabetes risk.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Behavioral intervention: sleep extension or sleep regularity

What this could lead to

If it works, this could point toward a simple, non-drug way to lower diabetes risk in people who are overweight and sleep poorly.

What could go wrong

This is a very small, early study (18 people) with no control group, so results may not apply broadly. The benefits may be modest or not last long-term.
