Study Shows All-Night Cramming is Counterproductive

A new study shows all-nighters can lead to worse grades.Once the fall semester is in full swing, college students across the country will find their days filled with homework assignments, projects, lectures and, of course, exams. While it may be tempting to cram for a big test by pulling an all-nighter, new research from the University of California, Los Angeles (UCLA) warns students that this is not the best strategy. In fact, all-night study sessions can be counterproductive.
While studying naturally helps students earn better grades, many individuals underestimate how important getting enough sleep is to their academic performance, the study says. As sleep is crucial to performing well in school, pulling an all-nighter can lead to worse grades on exams the following day, no matter how much students study.
"No one is suggesting that students shouldn't study," said Andrew J. Fuligni, a UCLA professor of psychiatry. "But an adequate amount of sleep is also critical for academic success. These results are consistent with emerging research suggesting that sleep deprivation impedes learning."
Typically, college students get an average of six to seven hours of sleep per night, according to the University of Georgia. However, to ensure their sleeping habits are not affecting their GPAs, associate's and bachelor's degree seekers should strive to sleep for six to 10 hours each night.
