Napping

The verdict is in: napping is good for you.

Napping in general benefits heart functioning, hormonal maintenance, and cell repair, says Dr. Sara Mednick, a scientist at the Salk Institute for Biological Studies who is at the forefront of napping research. A power nap, says Mednick, simply maximizes these benefits by getting the sleeper into and out of rejuvenative sleep as fast as possible.

Think you haven’t got time for a nap? Stuck at a work cubicle where everything you do is on display like a zoo animal?

THE NANO-NAP: 10 to 20 seconds Sleep studies haven’t yet concluded whether there are benefits to these brief intervals, like when you nod off on someone’s shoulder on the train.
THE MICRO-NAP: two to five minutes Shown to be surprisingly effective at shedding sleepiness.
THE MINI-NAP: five to 20 minutes Increases alertness, stamina, motor learning, and motor performance.
THE ORIGINAL POWER NAP: 20 minutesIncludes the benefits of the micro and the mini, but additionally improves muscle memory and clears the brain of useless built-up information, which helps with long-term memory (remembering facts, events, and names).
THE LAZY MAN’S NAP: 50 to 90 minutesIncludes slow-wave plus REM sleep; good for improving perceptual processing; also when the system is flooded with human growth hormone, great for repairing bones and muscles.
