College students and kindergartens love them. Now, there may be proof that catching a few zzz’s in the afternoon can be beneficial to your health.

Rest and relaxation isn’t only vital to your health — it might also make you a more creative person. People tend to be more imaginative after a good night’s sleep. Other experts agree that taking a nap or stepping away from a problem or project refreshes the mind and could lead to better ideas later. Power napping allows your brain to create the loose associations necessary for creative insight and opens the way for a fresh burst of new ideas. So if you feel stuck, then you might want to take a nap. Return to the problem after diverting your attention for a while. The best part is that there’s no need to feel guilty, because taking some “me time,” in this case, could help your business in the long run.

Naps aren’t just for the very young, old, and sluggish. Daytime dozing may enhance a person’s capacity to learn certain tasks. That, at least, is the eye-opening implication of a new study in which college students were challenged to detect subtle changes in an image during four different test sessions on the same day. Participants improved on the task throughout the first session. The students’ speed and accuracy then leveled off during the second session. The scores of the participants who didn’t nap declined throughout the final two sessions. In contrast, volunteers who took a 20-minute power nap after completing the second practice session showed no ensuing performance dips. What’s more, 1-hour power nappers responded progressively faster and more accurately in the third and fourth sessions. It looks like napping may protect brain circuits from overuse until those neurons can consolidate what’s been learned about a procedure.
