Start Times and Restful Sleep

Withdrawn before enrolling

Conditions studied: Excessive Daytime Somnolence, Sleep Deprivation

In brief

The purpose of this study is to evaluate the efficacy of later school start times in increasing student sleep, and examine the association between later start times and physical activity, screen time, and commute time. Subjects will wear a FitBit activity tracker wristband for two separate 3-month periods (the year before and the year after the Francis Parker High School start time change in the Fall of 2020) and be advised to wear it as much as possible, especially while sleeping or performing physical activity. At the beginning and end of each study period (at 4 occasions), subjects will fill out a few short, non-invasive surveys about their commute, after-school activities, sleepiness, and preferences for morning or evening, and perform the non-invasive psychomotor vigilance test to measure alertness.
