To Get Good Grades, Get Good Sleep

Research suggests that college students don't get enough sleep, and that they are far better off sleeping than cramming for exams. Steve Mirsky reports

You’d think that college students would be experts at sleeping.  But odd hours, parties, cramming for tests, personal problems, self-medication with drugs or alcohol and general stress can wreck a student’s sleep habits.  Which can be bad for the body and the mind.  Texas Tech University is even offering a class called "Improving Your Sleep Habits".  People suffering from sleep-deprivation are at an increased risk for obesity, diabetes, psychological problems and car crashes.  Students who don’t get enough sleep have poorer attendance and lower grades.
 
On top of all that, a new study published in the journal Learning & Memory finds that you’re probably better off sleeping than cramming for a test.  Two hundred college kids were taught to play a couple of video games that they were unfamiliar with.  Subjects who learned the games in the morning lost some skills when they played again 12 hours later.  But they did much better the next morning after getting a good night’s sleep.  So remember: if you really want to get those A’s, don’t forget to get some zzzz’s.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
