A few months ago, I wrote a guide to napping that included how, why, and when to flop down for a spell. That wasn’t a random throwaway post. It was the first salvo in a new war. I’m on a mission to legitimize the nap, to destigmatize the siesta for the average working human. And it’s not a selfish thing, because I can already pretty much take a nap whenever I want. I’m concerned about you. In a chronically sleep-deprived population such as ours, a 45 minute foray into the land of dreams can rejuvenate the mind, make up for sleep debt, and make us healthier and happier. Yet those who nap —or simply want to nap — often feel guilty about it, even if they have an hour or two to spare and are falling asleep at their desks. Perhaps it’ll make you feel better to know that some of the world’s greatest thinkers considered naps to be an integral part of their day — and their success.
