About this tool
Short naps refresh without deep sleep, while a full cycle nap of around 90 minutes lets you wake from lighter sleep again. Enter your planned nap and the minutes you usually take to fall asleep, and the tool labels the nap type and totals the time in bed. This is a general guide, not medical sleep advice.
