Napping can be beneficial, especially when nighttime sleep is insufficient, as it helps recover from physical and mental fatigue. Short power naps of 20 minutes are generally safe, but longer naps should be approached with caution to avoid disrupting nighttime sleep. Balancing cortisol, adenosine, and melatonin is crucial for optimal rest, and replicating a full sleep cycle of about 90 minutes during the day can enhance recovery.
