“Sleep, social life, or good grades,” my buddy said with a grin, “pick two.”
By now, you may have heard that statement about how busy life in college can get. With all kinds of student organizations to join, social events to attend, new people to meet, languages to learn, papers to write, and projects/problems sets/lab reports to complete, every college student wishes for more hours in a day. Sometimes, they get those extra hours by forgoing sleep.
Especially at a competitive school like UNC, people fall into the dangerous trap of taking pride in sacrificing sleep for academics. I’ve heard many UNC students brag about pulling an all-nighter in Davis Library. People even say things like “I can sleep when I’m dead.” or “Sleep is for sissies.” (That last one is advice a professor gave me my senior year at UNC).
Given the culture surrounding sleep on a competitive college campus, I know that getting people to prioritize sleep is going to be hard. But the research is clear: getting enough sleep has wide-ranging benefits in areas that are especially important to college students, like memory, focus, and stress.
Benefits of Sleep
Truthfully, researchers don’t really know why we sleep.
However, we do know that when sleep-deprived, our attention, focus, motivation to learn, creativity, ability to think abstractly, and vigilance are all decreased. This makes it harder to receive and properly process incoming information, and makes it more likely that we make sloppy errors in our work. In addition, our neurons don’t function properly, and we are less able to recall previously learned information. Can’t learn new things? Can’t remember old things? Lack of sleep takes its toll on the student’s brain.
In addition to negatively affecting memory both before and after learning, inadequate sleep impairs judgment, mood, motivation, and how we perceive events. Over time, poor sleep has been linked to obesity, diabetes, and depression. Lack of sleep can also lead to weight gain.
New research has even suggested that not getting enough sleep makes us appear unattractive and sad.
If you don’t get enough sleep over time, you build up a sleep debt.
So to be happier, sharper, smarter, and better at making decisions, get enough sleep every night!
Sleep is good. I get it. Now what?

It’s easy to let your school work slip into sleepy time, but that isn’t what’s best for your brain. So instead of pulling an all-nighter, plan ahead and break up studying into multiple smaller sessions. Sleeping between bouts of studying will help consolidate your memories and help you do better on your test. And when it comes to your social life, make sure you are taking into account how much sleep you have been getting before deciding to hang out with friends late at night.
If you are still having issues with sleep, feel free to walk in to UNC Counseling and Psychological Services in the Campus Health building. They are a great resource for helping students get better sleep, and they are familiar with meeting students with sleep issues as they are common amongst college students.
