😴 Nap Calculator
Enter when you want to nap and we'll tell you the best time to wake up.
⚡ Power Nap — 20 min
Boosts alertness and concentration without entering deep sleep. Perfect for a quick recharge.
🧠 Short Nap — 30 min
Enhances creativity and sensory processing. May cause slight grogginess on waking.
💡 Slow-Wave Nap — 60 min
Includes deep sleep — best for memory consolidation and learning. Some sleep inertia on waking.
🌙 Full Cycle Nap — 90 min
One complete sleep cycle including REM. Wake up fully refreshed with no grogginess.
☕ The Coffee Nap
Drink a cup of coffee, then immediately nap for 20 minutes. Caffeine takes about 20 minutes to kick in — so you wake up just as the caffeine hits, doubly refreshed. Studies show this combo is more effective than either coffee or a nap alone.
⚠️ Nap Timing Tips
- Best nap window: 1:00 PM – 3:00 PM (natural circadian dip)
- Avoid napping after 3:00 PM — it can disrupt nighttime sleep
- Set an alarm — oversleeping past 90 minutes causes sleep inertia
- A dark, cool environment helps you fall asleep faster
