Sleep timing, blood sugar control, and heart health in adults with type 1 diabetes
Official title: Circadian Mechanisms of Glycemic Control and Cardiovascular Risk in Adults with Type 1 Diabetes
Funded at University of Illinois at Chicago · NIH-11190878 · Data updated 2026-11-12
This project looks at whether making sleep longer and more regular helps adults with type 1 diabetes keep blood sugar steadier and reduce heart disease risk.

Who could benefit from this research
✓Could help
Adults (about 21 years and older) living with type 1 diabetes, especially those with short, irregular, or poor-quality sleep, are ideal candidates.
✕Less likely to help
People without type 1 diabetes or those who already have regular, sufficient sleep are unlikely to gain direct benefit from this specific project.
What this research studies
You would track your sleep and blood sugar while researchers measure blood pressure patterns and sleep-related hormones. Participants may wear a sleep monitor and a continuous glucose monitor, give urine or blood samples for melatonin metabolites, and have 24-hour blood pressure measurements. The team will offer a behavioral program to lengthen and regularize sleep and compare glucose control and cardiovascular risk markers before and after the program. The approach aims to show how improving sleep could lead to safer blood sugars and lower heart disease risk for people with T1D.
Why it matters
Potential benefit: If successful, this work could show that simple sleep changes help people with T1D manage glucose better and lower their cardiovascular risk.
How similar studies have gone: Earlier pilot studies and trials have shown that behavioral sleep interventions can improve sleep regularity and time spent in target glucose range, though the links to cardiovascular risk remain to be clarified.
