How long should a nap be?

For most people, a nap should be 15-30 minutes to boost alertness without causing grogginess (sleep inertia). Longer naps, around 60-90 minutes, allow for a full sleep cycle, which can be great for recovery if you're very sleep-deprived, but increases the risk of waking up in deep sleep feeling worse. The ideal length depends on your goal, but short power naps (10-20 min) are best for quick energy, while a full cycle (90 min) helps if you're exhausted, say experts.
