To Nap or Not to Nap
by James M Jackson

… that is a question I used to struggle with. Now, I am a confirmed napper. My preferred nap lasts 20-30 minutes. If I sleep longer than that, I wake up a grogamuffin—what scientists call sleep inertia—and I waste a bunch of time trying to wake up. Anything shorter than 10 minutes leaves me mentally unsatisfied, although often even a few minutes gives me a physical lift.

Studies show that naps that don’t result in sleep inertia are good for you (provided you are not driving a car or the like). Our workaholic society frowns on them. What’s your take?
