Improving cardiometabolic health through circadian interventions

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study examines the effectiveness of a circadian intervention aimed at improving cardiometabolic health in individuals with overweight and obesity who experience habitual short sleep duration. Participants will be randomly assigned to either a circadian intervention group, which focuses on reducing nighttime light exposure and late-night eating, or a control group that receives basic health information. The study will monitor sleep duration and assess insulin sensitivity through various tests over an 8-week period. The goal is to determine if adjusting circadian rhythms can lead to better health outcomes.
