What is a Power Nap ?

* A power nap is a short sleep which terminates before the occurrence of deep sleep or slow-wave sleep (SWS), intended to quickly revitalize the subject. The expression was coined by Cornell University social psychologist James Maas.

* In order to attain maximum post-nap performance, it is critical that a power nap be limited to the beginning of a sleep cycle, specifically sleep stages I and II.

* Scientific experiments and anecdotal evidence suggest that an average power nap duration of around 30 minutes is most effective. Any more time, and the body enters into its usual sleep cycle. People who regularly take power naps may develop a good idea of what duration works best for them, as well as what tools, environment, position, and associated factors help induce the best results.
