NCT ID NCT06627504
First seen Jun 24, 2026 · Last updated Jun 24, 2026
Summary
This study looks at whether improving sleep and circadian timing can reduce heart disease risk in adolescents with type 1 diabetes who typically sleep less than 7 hours per night. Fifty teens will follow a one-month program that includes a longer sleep schedule, a low dose of melatonin, reduced evening light, and morning bright light. Researchers will measure changes in insulin sensitivity, blood sugar control, and blood vessel function.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
melatonin (500mcg) plus behavioral sleep schedule, light reduction, and morning bright light
What this could lead to
If successful, this could point toward a simple, non-drug way to improve heart health and blood sugar control in teens with type 1 diabetes.
What could go wrong
This is a small, early-stage study with only 50 participants, so results may not apply to everyone. The intervention combines several changes, making it hard to know which part works.
