excerpt from \high schools, wake up to later start times: our view\ by the editorial board, usa today
high school students are wired to stay up late and sleep in later.
as another school year opens across the country, why on earth do 86% of the nations high schools start before 8:30 a.m., making it nearly impossible for teenagers to get the minimum eight - and - a - half hours of sleep their bodies crave?
there are lots of reasons, none having much to do with students welfare.
coaches, as well as many teachers and parents, like the crack - of - dawn schedule. it allows sports practices to end earlier, teens to be home to care for younger kids and teachers to beat the traffic.
bus schedules for entire districts, including later - starting elementary schools, are built around these early opening bells. the status quo is hard to change.
it shouldnt be this hard: the medical evidence is overwhelming that its the right thing to do. on monday, the american academy of pediatrics added its potent voice to the push for later start times, calling it a public health issue.
insufficient sleep is an epidemic: the average teen is chronically sleep deprived and suffering from some of the same symptoms as adults with serious sleep disorders, according to the groups report. biologically, it is difficult for teenagers to fall asleep before 11 p.m. and wake up before 8 a.m.
sleepy teens are more prone to be tardy, absent, moody, inattentive and less able to learn. that list alone is quite an argument for change.

even if the only benefit is healthier, more attentive teens, isnt that enough to make school boards wake up and ring the opening bell at a smarter hour?
