College students who are not well-rested have a greater chance of earning poor grades and withdrawing from a course compared to those who are well-rested, according to a recent study.
After studying 43,000 responses to the 2009 American College of Health Association National College Health Assessment (NCHA) survey, researchers found that the amount of time college students slept and how well they maintained healthy sleep habits were both strong predictors of academic problems. In addition, the study also found that sleep problems had about the same impact on GPA as binge drinking and marijuana use.
“Sleep problems are not systematically addressed in the same way that substance abuse problems are,” she said. “For colleges and universities, addressing sleep problems early in a student’s academic career can have a major economic benefit through increased retention.” The study, titled “What Is The Cost Of Poor Sleep For College Students? Calculating The Contribution to Academic Failures Using A Large National Sample” was published in the journal Sleep.
