This study is looking at how different amounts of sleep affect your heart health. We're studying people who sleep short hours (6 or less), long hours (9 or more), and average hours (7-8). We want to see if short or long sleep impacts your blood vessel function (vascular endothelial function), your risk for heart problems, and calcium buildup in your heart arteries (coronary atherosclerotic burden). You might also have the option to try sleeping 8 hours a night regularly for one week to see if it improves these measures. You could be eligible if you are between 25 and 65 years old, have a BMI between 18.5 and 40, and are generally healthy without certain medical conditions or medications. The study aims to see if an 8-hour sleep schedule can help improve heart health.

Study design

This is an interventional study with 24 participants, comparing three groups based on their usual sleep duration. There is an optional intervention where participants can maintain an 8-hour sleep schedule.

What's involved

You will use at-home devices to track sleep, physical activity, and blood pressure. There will be one or two in-lab visits for vascular function and blood tests, and an optional CT scan. The optional intervention involves maintaining an 8-hour sleep schedule for one week.

Compensation

Not stated in the trial record.

Follow-up

Measurements for vascular endothelial function, cardiovascular risk, and coronary atherosclerotic burden are taken at 2 weeks.
