Why 20 Minutes?
A 20-minute power nap keeps you in light sleep stages (N1 and N2), making it easy to wake up immediately and feel alert.
The 60-Minute Danger
Waking up after 60 minutes often happens during Deep Sleep. This cause "Sleep Inertia", leaving you feeling worse than before.
The "Coffee Nap" Pro-Tip
Drink a cup of coffee right before a 20-minute nap. The caffeine kicks in just as you wake up, doubling the alertness effect.
