Later start for high schoolers might make them safer

Is a school start time of 8:30 or 9:00 the answer to a happier and safer teenager? Maybe, according to an experiment in one district that suggests shifting school start times by one hour results in not only more sleep for teens, but fewer car crashes. Researchers surveyed thousands of Kansas middle school and high school students before and after the shift. Results showed that the percentage of those reporting eight hours of sleep rose from 36 to 50 percent.

And, perhaps more importantly, teen car crash rates declined more than 16 percent in the two years after the change.

There is more on this study in the Journal of Clinical Sleep Medicine.
