The Rise of the Power Nap
Embracing a Pandemic Perk: The Work-from-Home Nap
The COVID-19 pandemic brought remote work into our lives, making the power nap more popular. Now, people working from home can easily fit in a short nap during the day. A study showed that remote workers are twice as likely to nap at work than those in offices3.
Power naps are great for boosting productivity and making you feel better. A study looked at over 35,000 people and found that regular nappers had bigger brains. They also suggested that napping can make your brain age slower by 3 to 6 years3.
Power naps are good for more than just your brain. Taking a nap of 5 to 15 minutes can make you think better and stay sharp for up to three hours3. Napping in the late afternoon can also make you feel better and work better. Even top athletes, like Real Madrid footballers, nap to stay at their best.
As more people work from home, the power nap is becoming a common perk. It helps workers be more productive, focused, and happy, all from the comfort of their own homes34.

Understanding Sleep Cycles and the Benefits of Power Naps
Power naps are known for boosting cognitive function, increasing productivity, and making us feel more alert. To grasp their benefits, we need to explore sleep cycles and how they relate to these short breaks.
The sleep cycle has different stages, like light sleep, deep sleep, and REM sleep. Power naps, usually 20 minutes long, let us reach the REM stage without going into deep sleep. This avoids the grogginess that can come after waking up.5
Research shows power naps have many advantages. They help with performance, reduce stress, improve memory, and boost cognitive function. In Japan, short naps are common in workplaces and schools, known as Inemuri.5 But, naps over 30 minutes can make waking up hard.5
Coffee naps, mixing caffeine with a 15-20 minute nap, are great for alertness and brain function.6 Caffeine removes adenosine, a sleep-inducing chemical, making the nap more effective.6
Power naps also offer long-term benefits like lowering heart disease risk, improving mood, and making skin look smoother. A 60-minute nap can be as good as a full night’s sleep for memory, and daytime naps boost the immune system and cell function.7
By understanding sleep cycles and how to use power naps, we can gain cognitive and physical benefits. This leads to more productivity, better well-being, and a better balance between work and life.
“A ‘caffeine nap,’ combining a cup of coffee followed by a 20-minute nap, enhances energy levels by increasing caffeine receptivity in the brain.”7

In Japan, “inemuri” or “sleeping while present” is a big part of work culture. Taking short power naps during work is seen as showing hard work and dedication, not laziness8.

Power napping is seen as a way to recharge and get more done in Japan8. Unlike in other places, where sleeping at work is not allowed, Japan values power naps. They see it as a key to staying focused and energetic at work.

| Sleep Habits on Work Nights | Less sleep compared to other countries | More sleep compared to Japan |
| Prevalence of Power Naps | Common practice in the workplace | Less common in the workplace |

The Science Behind Power Naps
Power naps are based on the science of short sleep. A nap of 15-45 minutes can lower your body temperature. It lets your brain rest and relaxes your muscles. This leads to better memory, less tiredness, and more alertness9.
Why Do We Feel Recharged After a Power Nap?
Power naps use the body’s natural sleep cycles. The best nap time is 10-20 minutes, but up to 30 minutes works too, depending on how tired you are10. This short nap lets your brain enter a light sleep stage. It recharges your thinking and boosts your physical performance10.
Regular nappers get more benefits because they adjust their sleep-wake cycle10. The best time for a power nap is around 12:20 p.m. or 2 p.m. to fight sleepiness10.
Adding caffeine to a power nap can make you feel more alert10. Studies show that a 15-minute nap with caffeine helps with memory tests and driving simulations better than just napping or drinking caffeine alone11.
Power naps have many benefits but shouldn’t replace good sleep at night. If you’re not getting enough sleep, you might need longer naps or change your lifestyle to sleep better10.
| Benefit | Impact |
| Increased Alertness | Improved cognitive function and faster reaction time |
| Emotional Regulation | Enhanced mood and stress management |
| Physical Performance | Increased energy and muscle relaxation |
To get the most from a power nap, find a quiet, comfy spot. Avoid using devices and don’t nap too long10. By knowing how power naps work, you can use them to refresh yourself every day.

In Japan, taking a nap at work is seen as a sign of hard work. Many companies suggest short naps after lunch to help employees stay focused12. Some companies, like Nestle, even have special nap rooms for employees to take a 30-minute nap for a small fee13.
Power naps aren’t just for Japan. They’re also popular in places like Silicon Valley in the U.S. There, tech companies have special sleeping pods for employees to rest and recharge12.
Power naps can help fight “presenteeism,” where people are at work but not really working well because they’re tired or didn’t sleep well12. By offering nap spaces and supporting nap time, companies can make their employees work better and feel better13.
