Brief Summary
This is a digital health study in which participants are recruited to collect sleep and activity data from digital activity trackers. We are also collecting survey/questionnaire data on baseline health and sleep characteristics as well as bi-weekly assessments of sleep quality and mood. Overall, we aim to examine how sleep relates to physical and mental health in a large population of activity tracker users.
