Power nap
Meaning
A short, restorative sleep taken during the day to quickly improve alertness and performance.
Origin
Humans have always known the restorative power of a quick snooze. From ancient siestas to simply "resting one's eyes," the concept isn't new. But the term "power nap"—and its scientific validation—really took off in the late 20th century. Pioneers like Dr. Claudio Stampi, a chronobiologist, meticulously studied how even a short burst of sleep could dramatically boost alertness and performance. Think about it: NASA even explored these strategic naps for astronauts, showing how a mere 20-30 minutes could sharpen cognitive function and banish grogginess. This research transformed the humble nap into a recognized, effective tool, cementing "power nap" in our vocabulary as a smart strategy for a quick mental recharge.
Examples
