Even a short afternoon nap can help refresh the brain and improve its ability to learn, researchers say. The lead researcher, Professor Christoph Nissen of the University of Freiburg in Germany, said that even short naps can improve how the brain processes and stores new information. Sleep helps reset the brain. “A short nap can help you think more clearly and keep working with better focus,” he said. Because scientists cannot directly study brain connections in healthy people, they used safe, noninvasive techniques to measure brain activity.
