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.

What this could lead to
If it works, this could point toward a simple, non-drug way to help teens with overweight reduce their risk of diabetes.
What could go wrong
This is a small, early-stage study with only 60 participants, so results may not apply to all teens. The intervention combines several changes, making it hard to know which part helps.
