Randall Jeppesen reporting A lot of high school students are having problems staying awake at school, and it has nothing to do with the daylight-saving time change.
Around 28 percent of all U.S. high school students doze off during class, according to a researcher at Brown University.
School psychologist Anita Nielsen, at Riverton High School, says it's not hard to spot the sleep-deprived students. "They stay up late socially, or they work," she said.
Nielsen says research not only shows teens do need more sleep, but that they do better later in the day.
So some sleep researchers say school should start later. But Nielsen says that then messes up after-school jobs and extracurricular activities.
Other researchers have even suggested a nap time.
