NANO-NAP: 10-20 seconds. Sleep studies haven’t confirmed specific benefits to these brief intervals. However, if you aren't the driver, nod off on the way up the mountain and give us report when you arrive.MICRO-NAP: 2-5 minutes. Surprisingly effective at shedding sleepiness. Excellent location: in front of our lodge fireplace.
MINI-NAP: 5-20 minutes. Increases alertness, stamina, motor learning, and motor performance. Camp deck benches, perfect!
ORIGINAL POWER NAP: 20 minutes delivers benefits of micro and mini; additionally improves muscle memory and clears the brain of useless built-up info, which helps with long-term memory (remembering facts, events, and names). Your bunk beckons.
REAL WOMAN'S NAP: a FULL HOUR for 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. Tuck into that sleeping bag after lunch -- zzzzzzzzz, girlfriend.
