Sleep is crucial for producing higher levels of concentration, performance, and overall health and safety. Yet, teens, a vulnerable population, get far less sleep than the recommended 8-10 hours and continuously incur a sleep debt that negatively impacts their health. This troubling issue led to a national public health initiative to delay high school start times to benefit teens’ health. Though the Seattle school district recently accepted and implemented this initiative, it remains to be seen if the time change had the expected impact on the teens’ sleep quantity and therefore overall performance and health. The purpose of our research was to explore any correlation between the later school start time and positive outcomes of improved sleep, health and performance. In order to address this question, we created a 22-item survey which asks questions regarding quantity of sleep, self-reported measurements of mood and mental health, academic and extracurricular activity performance. We used convenience sampling and recruited from the community, specifically high schoolers within the Seattle school district who experienced the time change, to complete this survey. We expect to find that the later school start time increased the quantity of sleep high schoolers obtained, contributing to improved overall health and performance. If we obtain our expected results, we hope the data can be used to encourage other school districts to also adopt the time change and promote the health of the teen population.
