Better Than Coffee: Power Naps Can Do the Trick

Midday power naps can recharge your depleted batteries.

Anita Landoll, a special-education teacher at Halifax County High School, in South Boston, Virginia, counts herself lucky when she finds a few minutes to spare during the school day. When she has no scheduled meetings and no papers to grade during her planning period, she turns off the lights, lays her head on her desk, and dozes for five minutes. "Sometimes, I get so caught up with trying to meet demands that I just need a break," she says. "If I'm nodding off, I figure I need it." Afterward, she feels refreshed and ready to tackle the rest of the day.

Even though such midday naps are the norm for kids in preschool and kindergarten, they're considered a form of slacking for anyone with a full-time job. Now, however, a small but growing movement is bringing the benefits of the so-called power nap to people of all ages.

Corporations including Ben & Jerry's Homemade Ice Cream and smaller companies such as Yarde Metals, in Southington, Connecticut, have introduced nap rooms for their employees. In New York City, a business called MetroNaps has opened two "sleep-pod centers," where weary New Yorkers can come in off the street for twenty minutes of shut-eye in hooded, pod-shaped chairs for $14. Scientists say these businesses have it right: By allowing the brain to unload fatigue and mental clutter, midday naps lasting five minutes to an hour can help people heighten their learning skills and be more alert and productive.

"Sleep researchers still do not fully understand how the brain works during sleep," says Michael Twery, director of the National Center on Sleep Disorders Research, "but the evidence so far suggests that short naps can be good for those looking for a refresher during the day."

Recent studies show that short naps are beneficial for adults working any type of high-performance job. A NASA study found that an average nap of twenty-six minutes boosted airline pilots' performance by one-third. Hour-long naps involving rapid-eye-movement sleep can be even more beneficial. A 2003 study from the National Institutes of Mental Health showed that a sixty-minute nap reverses information overload and allows the same improvement in visual learning as six hours of slumber. Researchers tested two groups: One didn't sleep during the day, another took sixty- to ninety-minute afternoon naps. The first group's memory and learning skills tailed off into the afternoon and evening, while the latter fared significantly better.

The longer you rest, however, the more likely you'll be groggy when you wake up. Err on the side of too little sleep, and aim for a maximum of thirty minutes -- any more than that, and you'll enter the deeper, slow-wave sleep period between the thirty- and sixty-minute marks that is much harder to shake off during a workday. If you have time to doze for more than sixty minutes, your brain should shift back into a lighter sleep from which you can more easily perk up. Then, give yourself at least a minute to come out of the nap.

Power naps can be better energy boosters than caffeine, says Sara Mednick, lead researcher on the NIMH study and author of Take a Nap! Change Your Life. "Exercise can enhance memory process just as well, but there's a certain quality of boosting your learning capacity that is solely specific to sleep." Mednick is now doing a study comparing the effects of caffeine to power naps, and the results so far show that those using caffeine perform far worse than nappers on memory tests. A recent study from the Harvard School of Public Health and Greece's University of Athens Medical School suggests that regular midday naps can substantially cut your risk of heart disease, perhaps by reducing stress.

If you do get a few precious minutes for a power nap, how can you make the most of them? Find a quiet place that's not too hot, too cold, or too bright. The car is a popular spot (a survey of power nappers found that nearly 70 percent furtively catch a few winks in their backseat during lunch hour), as is a couch or a mat on the floor; teacher Anita Landoll appreciates her comfortable desk chair.

Put on some relaxing (or boring) music. If you worry you can't wake up on your own or find an alarm too jolting, mix a music CD that starts with quiet songs to induce you to sleep and concludes with louder, more energetic tunes. Alternatively, a company called pzizz sells software for your MP3 player that will create power-nap mixes for you.

It's ironic that our 24/7 society, which looks down on napping, is the same one that has been slowly but increasingly robbing its people of sleep. But as far as science is concerned, midday napping is finally getting some respect -- even if milk and graham crackers aren't included.

I love taking a nap during my work day. I agree with you that you should definitely under do your nap time as opposed to over do it. The thirty minute rule seems to work really well for me. I feel like I have a lot more energy and a boost in my ability to focus. However, while I do enjoy longer naps, I really have a difficult time going back into work mode. It's easy to forget how lucky you are when you get to work from, and this is just another added benefit.

As for those chairs, they look absolutely amazing. I really wish we had something like that here in Tucson. Unfortunately, I don't think there would be a market for it here as many businesses are located far from downtown and for the most part everyone is fixed to that 8 to 5 schedule.

Ever since I started using a CPAP machine to treat my sleep apnea, I haven't needed a nap! Don't get me wrong, I'm all for naps, but I really had no idea how badly I was sleeping at night until I actually started to sleep through the night again. If you need more then a quick cat nap, consider looking into how you're sleeping at night.

Not disputing the whole nap thing, but as an employer, I'm thinking if my employee has time to nap, he/she is not being used effectively! I am thankful for time to visit the bathroom and grab a cup of coffee. Napping is for weekends and lazy summer afternoons, and snow days. Anyone caught napping at our school is not back for the next year!

If only I didn't have to watch children for the 30 minutes of lunch that I get. (15min is always dedicated to someone getting make-up work/ help on something). Maybe one day we'll realize the importance on mental and physical health and the impact a healthier teacher will have on students.

I've had many different bosses and Principals over the years and the expectation has always seemed to be that every minute of the working day is spent in work-related activities. Those who came in early, left late, and committed every moment to work were seen as dedicated to their school and students. Until the scientists can make studies like this widespread, employees will run the risk of losing their jobs. How many Americans have you ever hear speak positively about siestas in Spain? Americans equate workaholic attitudes to success.

I don't nap at work but I can see the benefits. Here in Australia
we have a stop, revive survive campaign to reduce
The death toll on the roads. Teachers, even brilliant ones, get tired common sense should dictate that a few minutes of rest and rejuvenation
