Four Steps to Power Nap Like a Pro: 1  Find a good spot. Put your head down on a quiet table in the student lounge. 2  Keep it short. Shoot for a 20- to 30-minute nap. 3  Do it in the afternoon. That's usually the best siesta time.  Turn on some soothing sounds. If you have trouble dozing off, listen to relaxing music or a boring podcast.
Caffeine requires 20 or 30 minutes to take effect, so it will kick in just as you're waking. Naps of up to 45 minutes may also include rapid eye movement (REM) sleep, which enhances creative thinking and boosts sensory processing. Limit your nap to 45 minutes or less, if you need to spring into action after dozing. Otherwise, you may drift into slow-wave sleep. Waking from this stage results in sleep inertia, that grogginess and disorientation that can last for half an hour or more. But you might want to take a long nap, at least 90 minutes.
