Frequently asked

Why is the ideal nap time about 7 hours after waking?

Circadian rhythms naturally dip in the early afternoon, roughly 7–8 hours after waking, making it easier to fall asleep and get restorative rest.

How long should a power nap be?

10–20 minutes is ideal to boost alertness without entering deep sleep. Naps longer than 30 minutes can cause sleep inertia (grogginess).

Can I nap later in the day?

Napping too late (after 3–4 PM) can interfere with nighttime sleep. This calculator aims for the optimal early-afternoon window.
