Health experts and sleep therapists have provided guidance on effective daytime napping to improve energy and focus while avoiding ‘sleep inertia’—a state of heaviness and fatigue caused by waking from deep sleep.

Recommendations suggest limiting naps to approximately 20 to 30 minutes and scheduling them in the early afternoon to avoid disrupting nighttime sleep. Experts note that napping too late in the day can interfere with the body’s natural buildup of adenosine, potentially exacerbating insomnia. 

Additionally, specialists advise distinguishing between fatigue and sleepiness; while sleepiness may benefit from a short nap, those experiencing general fatigue without immediate sleepiness are encouraged to use physical movement instead.
