Most high schools begin their day around 7:30 a.m., which leaves many teenagers nodding off in the morning. In fact, at least 20 percent of high school students fall asleep in class on a typical day. The problem: Teenagers need a lot of sleep — about nine hours each night, experts say. And most of them aren't getting enough.
To help sleepy teens, some school districts have tried delaying the opening of the high school day. Educational researcher Kyla Wahlstrom, from the University of Minnesota, has been following districts that changed their start times, tracking the effect on schools and students. The Minneapolis school district, for example, changed its start time from 7:20 to 8:40 a.m., giving its 12,000 high schoolers an extra hour and twenty minutes each morning. Wahlstrom says the students have benefited from the change.
