A simple intervention can improve the sleep of college athletes, report researchers.
In a survey of 189 student-athletes, researchers found that 68 percent reported poor sleep quality, with 87 percent getting less than or equal to eight hours of sleep a night and 43 percent getting less than seven hours. About 23 percent of the athletes surveyed reported experiencing excessive levels of fatigue.
While seven hours is considered the minimum amount of sleep a typical adult should get, college students—especially highly active ones, like athletes—need at least eight to nine hours for optimal functioning, says Michael Grandner, assistant professor of psychiatry and psychology and director of the Sleep Health Research Center at the University of Arizona College of Medicine.
Grandner and Amy Athey, director of clinical and sport psychology services for Arizona Athletics, developed Project REST, which stands for Recovery Enhancement and Sleep Training, to encourage student-athletes to develop healthier sleeping habits.

“Student-athletes have a lot of reasons why their sleep would be disturbed,” Grandner says. “They have a lot of time demands, they have a lot of physical demands, they have a lot of mental demands, and they’re trying to balance athletics, academics, and sometimes employment, and this can set up the perfect storm for bad sleep.”
Poor sleep can have far-reaching effects, no matter who you are. For athletes, it can impact not only the way they feel physically and mentally but how they perform in their sport, Grandner says.
“Some of the most prominent effects of disturbed sleep can be reduced physical performance, reduced mental and cognitive performance, reduced recovery time from injury, and worse mental health,” Grandner says. Slower reaction times, impaired decision-making abilities, and even depression can result from poor sleep, he adds.
About Project REST
While many programs exist to address student-athletes’ nutrition and fitness, Grandner and Athey didn’t know of any that specifically target student-athletes’ sleep, so they developed Project REST, a model they hope college athletics programs nationwide will adopt.
Does a week of little sleep undo lots of studying?
The researchers enrolled 40 student-athletes in the intervention program, which started with a two-hour education and Q&A session that covered what good sleep is and why it is important and tips for improving sleep. Study participants then wore Fitbits to track their sleep habits over a 10-week period, and recorded information about the duration and quality of their sleep in online sleep diaries.
Throughout the study, students had 24/7 access to peers trained to support them and answer their questions. Participants also received daily text messages from study coordinators, including reminders about the study, tips for healthy sleep, and random sleep facts. About half of the participants also received sunglasses designed to block UV and blue light, and a programmable light bulb.
How the athletes responded
At the end of the study period, participants reported a number of positive effects, including better sleep quality, less insomnia, more energy, and less time spent lying awake in bed. Nearly 83 percent of the student-athletes said their sleep was better, and nearly 89 percent felt their athletic performance was positively affected. They also reported less stress and greater ability to focus.
The most useful part of the intervention, according to participants, was the initial information session. They also liked being able to monitor sleep habits with the Fitbit.
Athey, who works directly with the student-athlete population as a psychologist for Arizona Athletics, often encounters students with sleep issues, and says the data from the study back up what she already suspected anecdotally.
When students come to Athey with sleep issues, she encourages them to make minor lifestyle adjustments to improve sleep—maintaining a consistent sleep schedule or reducing exposure to mobile-device screens close to bedtime, for example—while more severe problems are referred to a sleep specialist.
Athey is optimistic that her partnership with Grandner, a sleep expert, can help introduce useful tools to the larger student-athlete population.
“With a really simple educational intervention and opportunities for learning over a number of weeks, student-athletes were able to make changes that had a real impact,” she says of Project REST.
While Grandner and Athey targeted the student-athlete population specifically, Project REST could be modified and adopted by different campus groups nationwide, since college students across-the-board often struggle with sleep, Grandner says.
“It’s just education and support,” he says. “There’s no reason this should be limited to student-athletes.”
An NCAA Innovations in Research and Practice Grant supported the work. The researchers presented their findings at the NCAA’s annual convention on Thursday, January 19.
