About the study

Previous studies have examined whether circadian rhythm tracking improves well-being, with some evidence suggesting that aligning daily activities with one's natural chronotype (a person's natural preference for being alert and sleep), enhances well-being and productivity. However, the current research lacks intervention-based designs like real-time tracking or behavioral alignment tools. Here, the investigators aim to investigate if an active intervention, involving the usage of an app tracking circadian rhythms and making recommendations based on one's circadian rhythm over seven weeks, improves students' flourishing.
