Every once in a while, my computer bogs down. Everything I do takes longer than it should. Some programs don't even work. When that happens, I do a forced shutdown and reboot the computer. A few minutes later, it runs like new. You can do the same thing for your brain. Rather than trying to think and do things with a fraction of your cognitive abilities, you can reboot your brain with a ten-minute power nap.



Some of the world's leading companies encourage employees to sleep during their workday. For several years, companies like Google, Zappos, and Uber have had designated nap spaces and "nap pods" to help their workforce refresh their minds at midday.Costa, D. (2017). "Should Employers Encourage Power Naps?" Harvard Business Review. Retrieved from hbr.org And no, they aren't doing this to be 'cool' or 'hip.' There's a science-backed reason behind it.



This midday snooze isn't your typical slumber; it's a 'power nap.' You might be wondering: "What is a power nap?" A power nap, as the name implies, is a short bout of sleep designed to quickly rejuvenate your brain, leaving you more alert, focused, and yes, more productive.Dhand, R., & Sohal, H. (2006). "Good sleep, bad sleep! The role of daytime naps in healthy adults." Current Opinion in Pulmonary Medicine. Retrieved from journals.lww.com



Reports indicate that after incorporating power naps into their daily routine, employees at these forward-thinking companies have seen noticeable improvements in job performance, creativity, and overall job satisfaction. This is where the power of a power nap truly shines.



In this article, we'll dive into the amazing brain-rebooting benefits of power naps, explore how long a power nap should ideally be, and discuss what happens to your brain during this period of rest. Along the way, we'll make sure you're armed with evidence-based knowledge so you can optimize your own routine for peak performance.

What is a Power Nap?



To put it simply, a power nap is a brief sleep that occurs during waking hours. But there's a bit more to it than that.



Scientifically speaking, a power nap isn't about catching up on lost sleep or lazily dozing off during a dull meeting.Mednick, S., & Ehrman, M. (2006). "Take a Nap! Change Your Life." Workman Publishing. It's a strategic, short sleep that's meant to revive your mental sharpness.Dinges, D. F., Pack, F., Williams, K., Gillen, K. A., Powell, J. W., Ott, G. E., Aptowicz, C., & Pack, A. I. (1995). "Cumulative sleepiness, mood disturbance, and psychomotor vigilance performance decrements during a week of sleep restricted to 4-5 hours per night." Sleep, 20(4), 267-277.



A power nap can last anywhere between 10 to 30 minutes. The key here is to keep it 'short.' Why? Because if you nap for too long, you risk entering the deeper stages of sleep, which can leave you groggy and disoriented when you wake up. This phenomenon is known as sleep inertia.



Think of a power nap as a pit stop for your brain—a quick, but effective pause in the midst of your daily race. Just like how a quick fuel top-up can help a racing car run more efficiently, a power nap is meant to recharge your brain, so you can zoom through the rest of your day with mental clarity and agility.Gillberg, M., Kecklund, G., Axelsson, J., & Akerstedt, T. (1996). "The effects of a short daytime nap after restricted night sleep." Sleep, 19(7), 570-575.



In the following sections, we'll delve into the science behind power naps and their benefits, and answer the question that's probably lingering on your mind: "How long should a power nap be?"



The Science Behind Power Naps



When you lay your head down for a power nap, what exactly happens to your brain? The answer lies in the unique architecture of sleep.



Sleep comprises cycles, each including various stages, from light sleep to deep sleep and the dream-infused Rapid Eye Movement (REM) sleep.Carskadon,
