The Science of the 20-Minute Power Nap

Research shows that a 20-minute nap is the sweet spot for refreshment. This duration keeps you in the lighter stages of sleep (stages 1 and 2), making it easier to wake up feeling alert rather than groggy. Sleeping longer risks entering deep sleep, which can cause sleep inertia - that disoriented feeling when you wake up. Check out our dedicated sleep timer for more nap presets and sleep cycle options.
