I love power naps. Give me 20-40 minutes of quiet or soft non-lyrical music and a flat surface and I can nap just about anywhere. But quiet is a luxury, I could even nap on a pool bench with multiple Fox-40 whistles being blown as a water polo game is in progress.
Just give me a power nap and I’ll be back fresher than ever. But extend my rest time past 40 minutes and the power part of the power nap is inversely affected. Then I feel groggy for the rest of the day. Then I stay up too late and have another low power day on the horizon.
So while a quiet space might be a minor concern for me and my naps, either a timer or alarm is an essential. I’ve got to keep that time in check, then I’m returning from my nap fully charged.
