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.
