How many studies support Recovery Sleep?

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 backed by 6 published studies in Vitaebase's database, including 3 meta-analyses, the most recent from 2023 -- a modest but real research base.
