This April marks the release of Arianna Huffington’s “The Sleep Revolution.” In it, the Huffington Post editor in chief dishes some hard-won wisdom on the importance of sleep in the master plan for your self-actualization, health and happiness.

While her tips include some familiar injunctions (banish tablets and smartphones from your bedroom; set a nightly routine and stick to it), one eyebrow-raising suggestion deals with the daytime hours. Arianna is a staunch advocate of “The Nap”.

She’s not alone. Companies including Procter & Gamble, Google and Facebook have been experimenting with “sleep pods” — spaces designated for napping and outfitted with comfy cots.

Of course, any nearby couch will do for a quick snooze. Or if you’re working from home there’s always the option of a commute to the bedroom. But it’s important not to overdo it. Sleep science suggests that twenty-five minutes or less is the ideal dosage for your midday nap. Novice nappers may even want to set an alarm.

The best interval for napping, based on our circadian rhythms, seems to be between 1:00 and 3:00 PM.

So: Will midday power naps catapult you to the top of the success ladder? There’s only one way to find out.
