Whatever you may think can get in the way of a successful college experience, chances are you won’t think of one of the most important factors: how long and how well you sleep, reports The New York Times.

And not just on weekends, but every day, Monday through Sunday.

Studies have shown that sleep quantity and sleep quality equal or outrank such popular campus concerns as alcohol and drug use in predicting student grades and a student’s chances of graduating.

Although in one survey 60 percent of students said they wanted information from their colleges on how to manage sleep problems, few institutions of higher learning do anything to counter the devastating effects of sleep deprivation on academic success and physical and emotional well-being. Some, in fact, do just the opposite, for example, providing 24-hour library hours that encourage students to pull all-nighters.
