A recent study at the University of Pittsburgh found that paying college students roughly $5 per night to sleep seven hours increased their sleep duration and improved their GPA significantly over a semester.
- Financial incentives raised sleep time by an average of 19 minutes nightly.
- Students meeting sleep goals improved their GPA by approximately 0.08 points.
- Sleep habit improvements lasted up to a month after payments ended.
What happened
Researchers at the University of Pittsburgh conducted a study involving over 1,100 undergraduates, equipping them with Fitbit trackers and an app to monitor sleep. A group of 468 students received about $5 per night whenever they slept at least seven hours. The intervention ran for four weeks and monitored sleep behavior and academic outcomes.
The students who received payments improved the frequency of nights with seven or more hours of sleep by 26% compared to those who did not receive incentives. On average, these students slept 19 minutes longer each school night, a meaningful extension in the context of typical college sleep patterns that often fall short of recommendations.
Why it feels good
Getting sufficient sleep is crucial for overall health and academic success, yet many young adults routinely get less than the recommended seven hours, putting their wellbeing and cognitive performance at risk. This study provides hopeful evidence that relatively small, immediate rewards can motivate healthier sleep habits.
The increase in sleep also translated to measurable improvements in academic performance, with students raising their GPAs by about 0.08 points during the semester of intervention. For freshmen adjusting to college life, the effect on sleep and grades was particularly strong, highlighting the importance of supporting healthy routines early on.
What to enjoy or watch next
After payments stopped, the improved sleep habits continued for several weeks, suggesting that small incentives can lead to lasting behavior change. Universities might consider redesigning schedules and deadlines to better support student sleep, along with experimenting with positive reinforcements.
Keep an eye on future studies testing sustainability of these effects over longer periods and exploring non-monetary methods to encourage sleep, as well as research on how better sleep impacts other areas of student health and wellbeing beyond grades.
