I find 15 minute naps the most effective way to reset and have a productive rest of the day. I don't do it every day, but I can feel when I need one and am operating at lower effectiveness. Anything longer is bad though - if you do 30+ minutes you're in danger of hours of grogginess. You may not feel the immediate benefit of a short nap, but you'll notice if you think about it an hour later how much fresher you are. Some people don't seem able to take naps. My advice is: give it a few tries. For me it took a few attempts for my brain to figure out how to shut down like that. And some days it just doesn't happen. I've found nothing better than taking some caffeine and immediately taking a power nap. When the refresh from both hit about 45 minutes later, it's like starting the day over, energy-wise.
