What this trial studies

This clinical trial investigates how alternating between short sleep during the week and longer sleep on weekends affects energy balance and cardiometabolic health in young-to-middle-aged adults. Participants will be assigned to one of three groups: those experiencing intermittent short sleep, those with social jetlag, and those maintaining adequate sleep. The study will last for four weeks and aims to determine whether a consistent sleep midpoint during short sleep periods leads to better health outcomes. The research addresses the real-life sleep patterns of many adults and their potential health implications.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 49 years with a BMI between 20 and 29.9 who habitually sleep 7-9 hours per night without the use of sleep aids.

Not a fit: Patients with sleep disorders, psychiatric conditions, or those who smoke may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into improving sleep patterns to enhance cardiometabolic health and reduce obesity risk.

How similar studies have performed: While some studies have explored sleep recovery effects, this approach of repeated intermittent short sleep is relatively novel and has not been extensively tested.
