Delayed high school start times in seattle increase sleep, grades and attendance

(American Association for the Advancement of Science) In Seattle, Washington, delaying the start time of two high schools by nearly an hour lengthened students' daily sleep by more than half an hour, and was associated with reduced sleepiness and increased academic performance. Notably, in the students at the school that was more economically disadvantaged, the delayed start time was also associated with an increase in punctuality and attendance.
