Frequently asked questions

What's the ideal nap duration for maximum alertness?

Power naps of 10-20 minutes are ideal for quick alertness without sleep inertia. Longer 90-minute naps complete a full sleep cycle for deeper restoration.

When is the best time to nap during the day?

The optimal nap window is typically between 1-3 PM, aligning with your natural circadian dip while leaving enough time before bedtime.

Can napping interfere with nighttime sleep?

Yes, naps after 4 PM or longer than 30 minutes can disrupt nighttime sleep. Strategic timing prevents interference with your main sleep period.
