Movie: More sleep means fewer car crashes for teenagers

BRIAN WILLIAMS, anchor: Some interesting stats out tonight tying the embark time of the school day with safety on the road for students. Researchers at Eastern Virginia Medical School found a direct correlation inbetween teenage driver car accidents and the time when school starts. In their investigate, the accident rate among teenage drivers was forty percent higher in one community where high school embarked at 7:20 in the morning, as compared to crash rates in a neighboring community where high school began more

When high schools embark too early, sleep-deprived teenagers are more likely to crash their cars, suggests fresh research.

The explore, which compared accident rates among teenagers in two adjacent counties in Virginia — one with schools that commenced extra early and one that embarked at a reasonable hour — confirms that teenagers are not designed to be morning people.

The finding also adds to a growing bod of evidence that later embark times can help adolescents earn better grades, get along better with their peers, build up control over their emotions, steer clear of drugs, avoid depression and even lower their risk of suicide.

“This examine did not prove by any means that early high school embark times led to enlargened rates of car crashes,” instead it shows an association inbetween early risers and car crashes, said Robert Vorona, a sleep doctor at Eastern Virginia Medical School in Norfolk, Virginia.

But combined with other research, he said, the evidence supports pushing school districts to switch their hours of operation. “Early high school commence times are problematic.”

Vorona’s youngest daughter inspired the fresh examine. With classes embarking at 7:20 a.m., she’s up by six a.m. on weekdays. After-school activities, sports and homework make it hard for her to get in bed before Ten. Already worried that his daughter might be sleep-deprived, Vorona discovered that high schools in a nearby county embarked more than an hour later. Instantly, he recognized a natural experiment waiting to be tested.

With the help of the Virginia Department of Motor Vehicles, Vorona collected data on the number of drivers inbetween ages sixteen and eighteen in two counties: Virginia Beach, where high schools embark at 7:20 a.m., and Chesapeake, where high schools begin at 8:40 a.m. The DMV also provided information about crash numbers.

The data displayed a clear difference inbetween the two counties. Among students who began class close to dawn in Virginia Beach County, there were 65.Four car crashes for every 1,000 teenage drivers. In Chesapeake County, there were just 46.Two crashes per 1,000 teenage drivers, Vorona reported this week at SLEEP 2010, a meeting of the Associated Professional Sleep Societies. That’s a forty percent higher crash rate in the county where school starts earlier.

While the explore doesn’t prove that getting up early is what’s causing kids to crash, other research supports the link.

A two thousand eight probe in the Journal of Clinical Sleep Medicine, for example, found that when high schools in Fayette County, Kentucky, switched their commence times from 7:30 a.m. to 8:30 a.m., teenage car crash rates dropped by more than sixteen percent.

Despite worries that later embark times simply give teenagers an excuse to stay up even later, studies demonstrate that teenagers get more sleep when their schools embark later, said Kyla Wahlstrom, director of the Center for Applied Research and Educational Improvement at the University of Minnesota, Twin Cities.

Rates of women who are opting for preventive mastectomies, such as Angeline Jolie, have enhanced by an estimated fifty percent in latest years, experts say. But many doctors are puzzled because the operation doesn’t carry a one hundred percent ensure, it’s major surgery — and women have other options, from a once-a-day pill to careful monitoring.

Part of the reason is biological. Around puberty, the bod’s circadian rhythm shifts so that the brain doesn’t get signals to sleep until eleven or 11:15 p.m. It doesn’t matter how tired a kid is or what time he got up that morning.

“I’ve done concentrate groups with hundred and hundreds of kids over the years,” Wahlstrom said. “They say, ‘My mom says to go to bed, so I go in there and lay there and look at the ceiling until eleven o’clock, and all of a unexpected I fall asleep.'”

The average teenager needs nine and a quarter hours of sleep, studies showcase. But with figures that can’t fall asleep until close to midnight and alarm clocks that sometimes go off before six a.m., it’s no surprise that teenagers are falling asleep in class and behind the wheel.

Besides pressuring their school districts to switch start-time policies, parents can encourage their teenagers to catch up on sleep when they can. It might help them to turn off their phones and computers by ten p.m., so they can embark winding down, Wahlstrom said.

And if your kid got far too few hours of shut-eye, don’t let her drive to school, Vorona said. She may hate to take the bus, but at least she can securely nap on it.
