Summary

This study tests whether helping children ages 6-12 who are above average weight and sleep 9 hours or less per night to get about 45 more minutes of sleep can improve their body weight and learning. The sleep extension group will be coached to go to bed 60-90 minutes earlier over 3 months. Researchers will measure changes in BMI, body fat, and memory skills, and follow up after 6 months.

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 to put children to bed 60-90 minutes earlier)
What this could lead to: If it works, this could point toward a simple, drug-free way to help children with higher body weight improve their weight and learning ability.
What could go wrong: This is a small, early-stage trial with only 142 children, and the sleep change may be hard for families to stick with. Results may not apply to all children.
