🧬 Science of Napping
• 20 minutes: Stays in light sleep (Stage 2), no sleep inertia
• 90 minutes: Complete sleep cycle (NREM + REM), wakes naturally between cycles
• Best time: 1-3 PM when circadian rhythm naturally dips
• Avoid: Naps after 3 PM may interfere with nighttime sleep
• Warning: 30-60 min naps cause grogginess (waking during deep sleep)

❓ What is a Power Nap Timer?
A power nap timer is a specialized tool that helps you nap for scientifically-optimized durations. Unlike a regular alarm, it's designed around your sleep architecture—offering either 20 minutes (power nap) to boost alertness without grogginess, or 90 minutes (full cycle) for deeper recovery with REM sleep benefits.
Timing is everything with naps. A 20-minute nap keeps you in light sleep (Stage 2), giving you a quick energy boost without sleep inertia. A 90-minute nap completes a full sleep cycle, including deep sleep and REM, which improves memory and creativity. The dangerous zone is 30-60 minutes—waking during deep sleep leaves you groggy. Our timer ensures you avoid this mistake.
