How does a power nap calculator work?

Our power nap calculator uses sleep science to determine the ideal nap duration (typically 10-30 minutes) that boosts alertness without causing grogginess.

What's the difference between a power nap and coffee nap?

A power nap is a short sleep (10-30 mins) for quick energy. A coffee nap involves drinking caffeine right before a 15-20 minute nap, allowing you to wake up as the caffeine kicks in for double the alertness.
