High School Daze: The Perils Of Sacrificing Sleep For Late-Night Studying
Published: August 21, 2012 by Allison Aubrey, NPR

It may not be the best strategy to stay up late and cram. A new study finds that when teens don't get the sleep they need, all kinds of things can go poorly.

High school students with heavy academic course loads often find the demands of homework colliding with the need for adequate sleep. And a new study published in the journal Child Development finds that when teens don't get the sleep they need on a given night, the next day all kinds of things can go poorly.

"What we learned is that when kids cram, particularly at the expense of sleep, the next day they're more likely to have academic problems even though they spent more time studying that night," explains researcher Andrew Fuligni of UCLA.

"These findings may come as a surprise to many researchers, educators, parents and teens who assume that more studying will surely lead to better grades," says Amy Wolfson, a professor of psychology at the College of the Holy Cross in Worcester, Mass.

The study builds on a body of evidence that finds sleep and learning are inextricably linked.

"Lots of things happen during sleep," explains Helene Emsellem, director of The Center for Sleep and Wake Disorders in Chevy Chase, Md. "We don't just physically restore ourselves." We also process all the information we've gathered during the day. "We take the information and organize it and make all the connections," Emsellem explains. Without adequate sleep, students don't learn as well.

Maybe this explains why rising 12th-grader Patrick Ottolini from suburban Washington, D.C., has realized it's not always the best strategy to stay up late and cram.

"If it's, like, a big test, it's not going to work at all," he says.

Instead of sacrificing sleep, he says, he has learned it's best to try to pace himself and find regular chunks of time each day to study. His classmate David LoBosco says he has another strategy that works for him: When it comes to prepping the night before a quiz, he finds it better to get some sleep and set the alarm.

"You know, wake up early in the morning and study," he says.
