A power nap or cat nap is a short sleep that terminates before deep sleep (slow-wave sleep; SWS). A power nap is intended to quickly revitalize the sleeper.

A power nap or cat nap is a short sleep that terminates before deep sleep (slow-wave sleep; SWS). A power nap is intended to quickly revitalize the sleeper. Cornell University social psychologist James Maas coined the term. A power nap combined with consuming caffeine is called a stimulant nap, coffee nap, caffeine nap, or nappuccino.

Cornell Universitysocial psychologistJames Maas coined the term.^[1] A power nap combined with consuming caffeine is called a stimulant nap, coffee nap, caffeine nap, or nappuccino.^[2]

Characteristics[edit]

The power nap is meant to maximize the benefits of sleep versus time. It is used to supplement normal sleep, especially when a sleeper has accumulated a sleep deficit.

Various durations are recommended for power naps, which are very short compared to regular sleep. The short duration of a power nap is designed to prevent nappers from entering SWS. Depending on duration and intensity, awakenings out of SWS results in sleep inertia, a phenomenon associated with grogginess, disorientation, and even more fatigue than prior to napping. Since sleep is the most effective and beneficial recovery method from fatigue, experts recommend considering duration vs. risk of entering SWS.^[3]

Research[edit]

Power naps intend to restore alertness, performance, and learning ability.^[4][5] A nap may also reverse the hormonal impact of a night of poor sleep or reverse the damage of sleep deprivation.^[6] A University of Düsseldorf study found superior memory recall once a person had reached 6 minutes of sleep, suggesting that the onset of sleep may initiate active memory processes of consolidation which—once triggered—remains effective even if sleep is terminated.^[5]

According to clinical studies among men and women, power nappers of any frequency or duration had a significantly lower mortality ratio due to heart disease than those not napping. Specifically, those occasionally napping had a 12% lower coronary mortality, whereas those systematically napping had a 37% lower coronary mortality.^[7]

A Flinders University study of individuals restricted to only five hours of sleep per night found a 10-minute nap was overall the most recuperative nap duration of various nap lengths they examined (lengths of 0 min, 5 min, 10 min, 20 min, and 30 minutes): the 5-minute nap produced few benefits in comparison with the no-nap control; the 10-minute nap produced immediate improvements in all outcome measures (including sleep onset latency, subjective sleepiness, fatigue, vigor, and cognitive performance), with some of these benefits maintained for as long as 155 minutes; the 20-minute nap was associated with improvements emerging 35 minutes after napping and lasting up to 125 minutes after napping; and the 30-minute nap produced a period of impaired alertness and performance immediately after napping, indicative of sleep inertia, followed by improvements lasting up to 155 minutes after the nap.^[8]

The NASA Ames Fatigue Countermeasures Group studied the effects of sleep loss and jet lag, and conducts training to counter these effects. A major fatigue countermeasures recommendation consists of a 40-minute nap ('NASA nap') which empirically showed to improve flight crew performance and alertness with a 22% statistical risk of entering SWS.^[9]

For several years, scientists have been investigating the benefits of napping, both the power nap and much longer sleep durations as long as 1–2 hours. Performance across a wide range of cognitive processes has been tested.^[9] Studies demonstrate that naps are as good as a night of sleep for some types of memory tasks.

A NASA study led by David F. Dinges, professor at the University of Pennsylvania School of Medicine, found that naps can improve certain memory functions.^[10] In that NASA study, volunteers spent several days living on one of 18 different sleep schedules, all in a laboratory setting. To measure the effectiveness of the naps, tests probing memory, alertness, response time, and other cognitive skills were used.

Power Napping Enablers and sleep timers allow properly timed power napping.

One study showed that a midday snooze reverses information overload. Reporting in Nature Neuroscience, Sara Mednick, PhD, Stickgold and colleagues also demonstrated that 'burnout' irritation, frustration and poorer performance on a mental task can set in as a day of training wears on. This study also proved that, in some cases, napping could even boost performance to an individual's top levels. The NIMH team wrote: 'The bottom line is: we should stop feeling guilty about taking that 'power nap' at work.'^[11]

Stimulant nap[edit]

A stimulant nap is a brief period of sleep of around 15 to 20 minutes, preceded by consuming a caffeinated drink or another stimulant.

It may^{[qualify evidence]} combat daytime drowsiness more effectively than napping or drinking coffee alone.^[2][12][13] A stimulant nap is more effective than regular naps in improving post-nap alertness and cognitive functioning.^[14][15] In a driving simulator and a series of studies, Horne and Reyner investigated the effects of cold air, radio, a break with no nap, a nap, caffeine pill vs. placebo and a short nap preceded by caffeine on mildly sleep-deprived subjects. A nap with caffeine was by far the most effective in reducing driving accidents and subjective sleepiness as it helps the body get rid of the sleep-inducing chemical compound adenosine.^{[16][unreliable source?]} Caffeine in coffee takes up to half an hour to have an alerting effect, hence 'a short (<15min) nap will not be compromised if it is taken immediately after the coffee.'^[17][18][19] One account suggested that it was like a 'double shot of energy' from the stimulating boost from caffeine plus better alertness from napping.^[2] This procedure has been studied on sleep-deprived humans given the task of driving a motor vehicle afterwards,^[20] although it has not been studied on elderly populations.^[21]

Nap rooms and tech aided naps[edit]

Some companies have nap rooms to allow employees to take power naps. This may be in a form of a nap room with a recliner, or chairs specially designed for power napping installed in a designated area. Companies with nap rooms say that employees are happier and become more productive at work.^[23]

Similar nap rooms and stations also exist in higher education institutions. Many colleges and universities provide napping furnitures such as cots and giant bean bags in libraries for students to take naps after long periods of study. At least one university^[which?] has a nap room set up in a gym. Some medical schools also set up nap rooms at teaching hospitals. The nap rooms may include sleeping pods or cots, white noise machines, and antimicrobial pillows.^[24]

In Barcelona, there is a café called Nappuccino^[25][26] that implements custom-built napping pods inside the café.

A more portable aid is a nap timer app. Apps have various features including aided sounds, nap history and pattern tracking and daily reminders that make it easier to take naps.

First look So, here it is at last, the latest big cat in the Apple game reserve. There are plenty of new features, and numerous improvements but are they enough to tempt Mac users who felt bitten by the radical changes Lion to upgrade?

Call of the wild: Mac OS X 10.8 Mountain Lion talks up its dictation functions

Well, OS X 10.8 is not all about bug fixes. First off, I’m dictating this review because one of the new features is the facility to enter text by voice. It’s pretty accurate, although I’ve since been back to tweak the text a little. It has strong word recognition and you can talk for ages or even pause at length, as you speak to it without a hitch.

It understands a sentence like “Is there any chance they’re playing their song?” This demonstrated it understood which of those homophones was needed at which time and I simply had to say ”Question mark” at the end for it to insert the appropriate punctuation. It’s not perfect, for instance, it doesn’t take kindly to expletives, but it’s certainly good enough to have speech recognition companies worried.

Talk your text when messaging: there was a time when people would use the phone

Not Nuance, though. Its technology is behind some Apple products, presumably including Siri, the iPhone 4S voice recognition feature, so it’s almost certainly involved here. Dictation is a neat feature, launched by pressing the function key twice. How much I will use it in the future is anybody’s guess, especially in a busy office with company and background noise. But for now, it’s proving both useful and fun. It works across the system, so you can as easily dictate to Microsoft Word as you would Messages.

Now, Messages has already been available as a beta on Lion and it enables you to send iMessages from your Mac to other Mac users running the app and iOS devices too. It’s rather like BlackBerry users have BlackBerry Messenger but on the Mac you get a desktop version. However, you'll need to be running Mountain Lion now. Still, any iPad, iPhone and some versions of iPod touch can receive iMessages complete with text, photos or even videos. Like BBM, you can see when the other party is typing their response.

There are, apparently, 200 new features in Mountain Lion or, as we at Reg Hardware have taken to call it, Hillside Cat. Many of these are things many users will never knowingly come across and anyway, you don’t want to read a list here – Apple has one instead. Still, Mountain Lion has headline features which certainly catch the eye. Chief among these is Power Nap, which persuades your Apple Mac to do some work when it’s sleeping.
