Why we should all take a nap in the afternoon

It turns out we need a nap during the afternoon. And historically, it seems we've always needed one. There is the Spanish concept of siesta. Italians call it riposo. If you go to China, you are likely many businesses shut down between 11:30 - 2:00 pm. They take a combination lunch and siesta before going back to work. Americans used to call it a power nap, but the research world calls this a nap zone.
The research world calls this the nap zone. Other benefits have been found, mostly related to changes in memory performance. Both declarative and procedural memory tasks improve if you take a regular nap. One paper has the delightful title - and remember, this is a research paper "Good sleep, bad sleep! The role of daytime naps in healthy adults.
I have personal experience with this, and I bet you do too. When I don't take a nap in the mid-afternoon, I typically fight being drowsy from about 1:30 on. If I do take a nap in the mid-afternoon, just a small one, I suddenly get a burst of energy and an alertness that allows me to be productive the entire day. I am pleased to say this anecdotal information has strong empirical support.
