Kyla Wahlstrom, director of the Center for Applied Research and Educational Improvement (CAREI), discusses her research on the negative effects of early school start times on teenagers in a recent MSNBC story on car accident rates among teens. The focus of new research suggests that when high schools start too early, sleep-deprived teenagers are more likely to crash their cars. These new studies build on the ground-breaking work of Wahlstrom and CAREI that established the benefits of later high school start times for students.
