Researchers paid students about $5 a night to reach seven hours of sleep. The results suggest colleges may be overlooking sleep as an academic intervention.

Researchers at the University of Pittsburgh paid 468 undergraduates about $5 for each night they slept at least seven hours over a four-week period. Compared with 380 students who received no financial incentive, the paid group reached the seven-hour mark on 26% more nights, slept about 19 additional minutes per school night and posted an average GPA increase of about 0.08 points that semester. The study, published in July 2026, involved more than 1,100 students whose sleep was measured using Fitbit devices.

The experiment also showed that information alone was not enough to change behavior. Students received bedtime reminders and morning feedback through an app, but those interventions produced only small improvements without money attached. Immediate rewards worked better than delayed ones: paying students each morning produced a stronger effect than promising the same compensation as a lump sum at the end of the semester. The findings suggest the challenge was not simply knowing that sleep matters. Most participants already said they wanted more sleep than they were getting.

Some of the change continued after the payments stopped. Students who had received the incentive were still sleeping about eight minutes longer per night during the following three to four weeks. The academic effect also lasted into the next semester before researchers could no longer detect a difference two semesters later. The gains were largest among first-term freshmen, whose college routines were still being established.

For universities, the useful question is not whether every student should be paid to sleep. It is whether sleep belongs more explicitly inside student-success strategy. Late-night assignment deadlines, early classes and first-year scheduling all shape when students go to bed, while colleges routinely spend heavily on tutoring, advising and academic support after performance problems appear. This study suggests some interventions could begin earlier, by reducing the conditions that make adequate sleep harder to maintain.

The broader takeaway is straightforward: helping students sleep more changed both behavior and academic performance, even when the nightly increase was modest. That gives colleges another variable to test alongside tutoring, course design and advising when they ask what actually helps students succeed.
