Feeling exhausted in the middle of the day is a common problem for many Americans. Whether you’re struggling through an afternoon slump, dealing with poor sleep the night before, or trying to stay productive at work, a nap can seem like the perfect solution. But there’s one important question: How long should a healthy nap be?
The answer isn’t always straightforward. A nap that’s too short may not provide enough refreshment, while a nap that’s too long can leave you feeling groggy and disrupt your nighttime sleep. Understanding the ideal nap length can help you improve energy, focus, mood, and overall wellness.
This guide explains the science behind healthy napping, ideal nap durations, benefits, risks, and practical tips for making naps work for you.
Quick Answer
A healthy nap should typically last 10–30 minutes for most adults. Short naps can boost alertness, focus, and mood without causing grogginess. Longer naps of 60–90 minutes may provide deeper recovery but can increase the risk of sleep inertia and may affect nighttime sleep if taken too late in the day.

A healthy nap is a short period of sleep taken during the day to improve alertness, recovery, and mental performance without negatively affecting nighttime sleep.
Unlike nighttime sleep, naps are meant to:
- Restore energy
- Improve concentration

Healthy naps are especially useful for:
- Office workers
- Students
