I’m reading the book Brain Rules. The author, a developmental molecular biologist, delves into how the brain works and the best ways to accomodate learning and high work performance. I wanted to share a bit from a section that discusses sleep and its importance in learning.
- A NASA study found that a 26-minute nap improved a pilot’s performance by 34%.
- Another study found that a 45-min nap boosted cognitive performance for more than 6 hours.
- Students given a series of math problems and shown one of the many ways to solve them were then given 12 hours before being asked to solve them again. After 12 hours, 20% had found a shortcut to the problems. But, if in those 12 hours the students were allowed about 8 hours of sleep, 60% had discovered a shortcut. No matter how many times the experiment is run, the sleep group consistently outperforms the non-sleep group 3:1.
So there really is something to the phrase “sleep on it!”
