This study is looking at how different light exposure patterns and eating times affect your metabolism (how your body uses food for energy) when you're getting less sleep. Researchers are testing two behavioral interventions: dimming light during the first four hours of being awake and having bright light at night (Central Clock Misalignment), and eating most daily calories later in the day (Peripheral Misalignment). The study aims to see how these changes impact your body's ability to use insulin (Insulin Sensitivity) and your internal body clock (Internal Circadian Misalignment). You might be able to join if you are 18-35 years old, have a healthy body mass index (BMI), and usually sleep 7-9 hours per night. The current recruitment status is unclear.

Study design

This is an interventional study with an estimated 120 participants. It's a randomized, in-lab, cross-over trial where each participant will experience all three study conditions.

What's involved

You would attend 6 to 8 in-person visits to the study clinic, including three overnight stays. You will complete surveys and medical tests over approximately 4 to 6 months.

Compensation

Not stated in the trial record.

Follow-up

Insulin sensitivity and internal circadian misalignment will be measured immediately following a 5-day sleep restriction segment.
