How longer daily eating times might affect heart risk in adults who sleep less than six hours.

Cardiovascular risk and circadian misalignment in short sleepers- role of extended eating period.

NIH-funded research Lsu Pennington Biomedical Research Ctr · NIH-11127485

This project explores whether a longer daily eating window shifts the body's clock and raises heart and metabolic risk for adults who usually sleep six hours or less.

What this research studies

You would be asked to join a study at LSU Pennington that looks at how the timing and length of your daily eating affects your body clock and heart health if you typically sleep six hours or less. Researchers will track your sleep timing, melatonin patterns, ambulatory blood pressure, and blood measures related to insulin and metabolism while observing or altering your daily eating window. The team will compare shorter versus extended eating periods to see if late or prolonged eating causes circadian misalignment and metabolic harm. Visits will be in-person and may include timed meals, blood draws, and wearing monitors between clinic visits.

Who could benefit from this research

Good fit: Adults aged 21 and older who habitually sleep six hours or less most nights and can attend in-person visits in Baton Rouge are ideal candidates.

Not a fit: People who regularly get adequate sleep, are under 21, or have certain unstable medical conditions may not benefit from or be eligible for this project.

Why it matters

Potential benefit: If successful, the results could suggest simple meal-timing changes that lower blood pressure and metabolic risk for people who cannot increase their sleep time.

How similar studies have performed: Prior studies show that increasing sleep can improve metabolic health, but using eating-window timing to reduce circadian misalignment in short sleepers is a relatively new and not yet well-tested approach.
