Alcohol, sleep, and school work: College drinking and GPA

July 2nd, 2011

Co-authored by: Jamie Felzer

We all know that college students often party and sleep more than they actually study.  But do heavy alcohol use and poor sleep patterns cause poor grades?

A recently published study found that just altering bed times by 2 hours can throw off your sleepiness during the day.  Most students in the study did show a 2-4 hour difference in daily bed times between weekdays and the weekend, and most went to bed after midnight.

The average number of drinks for participants came in around 6 drinks a night (equal for men and women).

The big question is: can these heavy drinkers in college still perform well academically? (See here for influential factors in college drinking)

No matter what the cause, insufficient sleep causes poor academic consequences.  Interestingly, those students who reported much more sleep also had lower GPAs (oversleep was mostly assumed, by the researchers, to be caused by drinking and staying up too late, though it could have been due to other issues such as depression).

Overall, those that drank more often went to sleep later and also had bigger gaps between weekday and weekend bedtimes, all of which correlated very highly with a lower GPA.
