Napping Well, Aging Well

Marcus Bly

A quick nap can leave you sharper, or it can leave you groggy and wreck your night's sleep entirely. This is the guide to getting it right: the window of time that keeps rest restorative, the length that avoids deep-sleep hangover, how naps shift as the decades go by, and the warning signs that daytime tiredness deserves a closer look. Practical, clear-eyed, and built for the way real afternoons actually go.
