Lack of sleep can cause someone to take a snooze in class, or it can cause someone to divorce their wife, gamble their money away, and make a series of bad decisions. This was the case for Peter Tripp, a radio DJ who stayed awake for 201 hours in 1959 to break a “wake-a-thon” record. While college students generally don’t take their sleep deprivation to that extent, they are harming themselves and impairing their studies by failing to sleep an adequate amount, says University of Massachusetts Amherst psychology professor Rebecca Spencer.
Sophomore environmental science and BDIC in environmental advocacy and policy double major Arianna Moscone said that chronic sleep deprivation has taken its toll on her academic performance and physical health. “I’ve been trying to get better,” she said. “I’ve been going to bed an hour earlier than I usually do because I know that the effects it had on my body last semester. I need to make my body rest. I’m still really tired all the time though.”
Spencer and others at UMass Amherst have conducted research on the effects of sleep on memory and complex cognitive skills like decision-making. According to Spencer, the way the brain revisits information while you are asleep helps to solidify information and make for more informed decisions. The process of called memory consolidation, the way the brain combines information from multiple sources like in-class lectures and related homework readings, is important for the retention of facts. Compromising sleep in favor of staying up all night to study for an exam means giving up the long-term benefits to memory of sleep.
“If you learn something and then you fall asleep you’re going to recall more than if you stay awake. If you study something before sleep tonight, not only will you be able to better recall it in the morning, but you’ll also be able to better recall it during that cumulative exam at the end of the semester,” said Spencer.
“The latest I stay up before an exam is two, and I usually try to go to bed at like eight or nine, said sophomore finance major Jillian Wybanga, who prioritizes sleep over last-minute studying before important exams. “I’m basically a grandmother.”
Adrienne Breef-Pilz, a senior biology major, is a resident assistant and an athlete on the rowing team. She wakes up at 5:45 a.m. for her practices, and said that she sleeps for between four to six hours a night. Some people on her team, Breef-Pilz said, get even less. “Some people will be in the library doing homework at two or three a.m., or they’ll say, ‘Oops, I pulled another all-nighter.’”
‘Pulling an all-nighter’ can be beneficial for some in terms of short-term exam performance,” said UMass PhD candidate Akshata Sonni, who is studying neuroscience and behavior and conducts research on sleep and memory with Spencer in the UMass Cognition and Action (“Cognac”) Lab. “But it really depends on an individual student’s goal in learning information and studying. “That information will never get filed away, and you’ll never remember it after that exam’s over; by the end of the day you would have forgotten most of it,” said Sonni.
Spencer said that for some, staying awake to study can potentially have short-term drawbacks, though. “The worst thing, though, you can do is sleep deprive yourself to study. That’s when you’ll sleep through the exam, or be inattentive during the exam. That’s the problem with an all-nighter,” Spencer said.
Moscone, though, said she often relies on this method. “Sometimes there’s just physically not enough time during the day for me to study for that exam so I sort of have no choice but to stay up all night, and that also has to do with procrastination. Sometimes I’ll take an exam and leave and just not remember anything and think I did okay, and then end up doing horribly.”
In addition to the brain’s ability to better solidify previously learned information while you are asleep, it is easier to accrue new knowledge when well rested.
“Not only do you need sleep, just your normal healthy amount of sleep to consolidate what you’ve just learned, but you also need the sleep and the lack of sleep deprivation in order to stay focused and attentive,” said Spencer. She emphasized that the benefits of sleep and the impairing effects of sleep deprivation were two independent processes. “That’s not saying the same thing two different ways; they are independent. You need both of them.”
The amount of sleep needed for decision-making and memory varies from person to person and changes with age. College students are technically still in the upper limits of adolescence, said Sonni, and therefore need more sleep than older adults. “I think a very small percentage of college students actually get nine hours of sleep. Most college students are chronically sleep deprived,” Sonni said.
College students’ schedules are very busy, said Sonni, explaining that time spent on classes, extracurriculars, homework, and social life leaves little time for sleep.
“I really think that college students, if they get less sleep, choose to get less sleep. There’s a fair amount of procrastination, and that happens mostly during the day. Then you make up for it at night when you’re doing work because during the day you were socializing. At night when you should be sleeping you’re catching up on all that,” said Wybanga.
Procrastination for Moscone is largely due to what she terms “FOMO”: the fear of missing out. This especially affected her while making new friends during her first year of college; “I was like, well everyone’s still hanging out and I’m tired, but I’m going to stay up until everyone else goes to sleep because I don’t want to miss anything,” Moscone said.
For Breef-Pilz, that lack of sleep affects her both her athletic and academic performance. “It affects us much more than we’d like to admit,” she said with regard to her team’s collective lack of sleep.
While most students can wake up right before class, Breef-Pilz said, she has to work out for an hour and a half every morning before lecture; by that point, she’s already tired. “Falling asleep in lecture is definitely a problem for me,” she said. “I’ve dozed off during exams.”
“Students who sleep deprive themselves during the week, and then make up for it on the weekend, they’re doing themselves a disservice, because then on Monday they’ve reduced their sleep load and lost their ability to sleep. Their sleep load is gone,” said Spencer. These students, she said, proceed to sleep an inadequate amount and repeat the process week by week.
In reality, said Moscone, catching up on sleep on weekends is not entirely feasible, because sleeping in is balanced by staying out and going to bed later.
More important than a set minimum amount of sleep is a consistent sleep schedule, said Spencer and Sonni, which differs for every person. This can consist of a regular bedtime or napping to compensate for less overnight sleep.
“I nap every day. I’ll even take a nap in the bus on the way to practice,” said Breef-Pilz.
Naps can sometimes have the adverse effect of getting you out of your normal sleep rhythm, said Spencer. But being attuned to attentiveness and physical exhaustion is important, Sonni said, because when you feel like you need to rest you probably do.
Habitually napping, or using naps to compensate for not enough sleep can be beneficial. Said Spencer, “Naps can have the same benefit as overnight sleep. All these functions - memory consolidation, better decision making - all of those functions you can get from a nap, even a very short nap.”
Said Wybanga, “I nap probably like twice a week. I’d like to nap everyday.”
