Earlier Sleep Linked To Better Weight-Loss Results In Prediabetes Study
What Happened
A randomized controlled trial led by NYU Rory Meyers College of Nursing studied 196 adults aged 21-64 with prediabetes who slept less than 6.5 hours a night. Participants completed an eight-week diabetes-prevention lifestyle programme, with one group also receiving sleep coaching designed partly to shift bedtime earlier. The added sleep programme improved sleep and reduced daytime sleepiness, but did not improve blood-sugar levels. Researchers found that going to sleep earlier was associated with greater weight loss, suggesting sleep timing may be worth considering alongside diet and physical activity.
Key Takeaways
The study links earlier bedtimes with greater weight loss, but it does not establish that simply going to bed earlier will cause weight loss. The findings instead point to sleep timing as a potential factor worth studying further in people with prediabetes.
