If you experience persistent fatigue, excessive daytime sleepiness, or sleep problems, consult a healthcare provider. Do not nap if you have been advised against it by a medical professional.
How It Works

Our Power Nap Calculator uses sleep science research to determine your optimal nap duration and timing based on four key factors:

  • Sleep Pressure: How long you've been awake determines adenosine buildup - the chemical that makes you sleepy.
  • Chronotype: Your natural sleep-wake preference affects when you experience your afternoon dip.
  • Energy Level: Your current fatigue level helps determine whether you need a quick boost or deeper recovery.
  • Post-Nap Activity: Different activities benefit from different nap types (e.g., driving needs alertness, creative work benefits from REM).
About This Tool

Nap Types Explained

  • Micro Nap (5-10 min): Quick reset when short on time. Provides mild alertness boost.
  • Power Nap (15-20 min): Ideal balance - boosts alertness and mood without grogginess.
  • Recovery Nap (60 min): Includes deep sleep for physical recovery. May cause some grogginess.
  • Full Cycle (90 min): Complete sleep cycle with REM. Best for creativity and memory.
  • Caffeine Nap (20 min): Drink coffee then nap - wake as caffeine kicks in for maximum effect.

Limitations

  • This is an educational tool, not medical advice
  • Results may vary based on individual physiology
  • Health conditions and medications can affect napping
