Sleep in for safety — another sleep update


No news for Kevin today from the annual SLEEP conference but something for the road safety boffins to consider. A new study found that earlier high school start times are associated with higher teen car crash rates.
National Public Radio reporting from the conference in San Antonio reports that researchers compared two neighboring cities in Virginia with similar racial and income demographics: Virginia Beach, where the high school day began at 7:20 a.m., and Chesapeake, where classes began 80 minutes later. Using 2008 data from the Virginia Department of Motor Vehicles, researchers found that the car crash rate for 16- to 18-year-olds was about 41 percent higher in Virginia Beach.
Though the study isn’t proof, researchers figure the difference may be due to sleep deprivation and a disruption of teens’ internal clocks. He might not be a teenager but thank goodness Kevin has a chauffeur!
