Is Recovery Sleep good for sleep quality?

The evidence points that way, though it's not yet conclusive. A systematic and meta-analytical review found acute sleep loss measurably impairs physical performance, and a classic controlled study of collegiate basketball players found extending sleep to 10 hours per night improved sprint times, shooting accuracy, and reaction time — one of the more concrete real-world demonstrations of sleep's performance value. That's reflected in an evidence score of 48/100 for its role in sleep quality, drawn from 6 studies, with an estimated impact on longevity rated moderate (42/100).
