Latin American Cultures Have It Right - Let's Nap

All right. I know that an Email Management Blog is not the place you
expected to see a post about napping, but in light of recent articles,
I thought it might be an interesting read. It is, actually, a very
relevant issue when it comes to better performance and happier people
(so they say). In Latin America (and many other cultures), a siesta is
not just a guilty pleasure, it is a way of life. Everyone goes to work,
comes home for lunch, takes a quick nap and returns to work. The
typical work day tends to be a bit longer and it definitely helps pass
the time when the rains unleash in afternoons, but who cares - at least
they are getting a bit of rest in between. I love vacationing there for
that very reason. But why wait for time off?

So what do the scientists say? Some recommend power naps of 15-20 minutes for a quick pick-me-up. Web Worker Daily also reports that a 90-120 minute nap is also beneficial. Anything in-between is not restful enough to make much of a difference.

Better yet, maybe you should log off and conduct your own experiment by catching a few zzz's yourself.
