First seen Jun 02, 2026 · Last updated Jun 22, 2026 · Updated 2 times

Summary

This study looks at whether improving sleep habits can help teenagers with overweight or obesity better regulate blood sugar and energy. Researchers will enroll 60 teens aged 14-19 who get less than 7 hours of sleep on school nights. For two weeks, participants will follow a sleep plan that includes an extra hour in bed, a melatonin supplement before bedtime, and bright light after waking. The goal is to see if these changes improve insulin sensitivity and daily energy use.
