A recent study involving University of Pittsburgh undergraduates explored the impact of financial incentives on sleep patterns and academic results. Students, with an average age of 19, were offered around £3.76 for each night they achieved more than seven hours of sleep.
The findings indicate that students receiving these payments slept an average of 19 additional minutes per school night compared to those who did not. This also meant they met the optimal seven-hour sleep target on 26% more nights.
Academically, the rewarded students experienced a modest but significant improvement, with their grade point average (GPA) increasing by an average of 0.08 points. This improvement was particularly noticeable among first-year students. The study also noted that some effects, such as increased sleep and higher grades, persisted even after the monetary incentives ceased.
