Frequently Asked Questions

What is the ideal length for a nap?

For most people, a 20-minute power nap or a full 90-minute sleep cycle provides the best results without causing grogginess.

What is sleep inertia?

Sleep inertia is the heavy, groggy feeling you experience when waking up abruptly from deep slow-wave sleep.

When is the best time of day to take a nap?

Early to mid-afternoon (between 1:00 PM and 3:00 PM) is usually ideal because it aligns with the body’s natural circadian dip.

Most healthy adults take about 10 to 15 minutes to fall asleep after lying down.
