For a behind the scenes look into some of the articles we read when we create the show, check out our Pocket collection at http://getpocket.com/slate. Every day around 2:00 p.m. Rob hits a brick wall. A busy job and two young children have zapped all of his energy, and he’s desperate to do something—anything—to make it through the rest of the workday. Enter the elusive and often guilt-ridden midday nap. But there too Rob struggles to really rest and then wake up without making things worse. On this episode of How To!, we bring on Dr. Sara Mednick, author of Take a Nap! Change Your Life and the forthcoming book The Hidden Power of the Downstate. Sara draws on years of research at her sleep lab to advise Rob, and all of us, how to stay energized during a long day (Hint: It might not involve napping at all).
