Students and adults who want to learn and remember information better might focus on getting better sleep, suggests a new study published in the Journal of Neuroscience. Researchers at Brown University studied two groups of people to determine how sleep affects learning and memory. Both groups were given a variety of tests and training. Participants took a 90-minute nap, and the researchers studied how much they retained after the period of sleep. They found that sleep helped participants absorb what they learned while they were awake. The study shows that the more sleep you get, the more time your brain has to process knowledge and skills you learn while you are awake. High school and college students might consider going to sleep at a normal time instead of staying up late to cram for tests.
