Power Nap Wikipedia
Power Nap even has its own section in wikipedia.
A power nap (sometimes called a catnap) is a short nap, usually 15-30 minutes. The term was coined by Cornell University social psychologist James Maas. It is thought by many to maximize the benefits of sleep versus time. This type of sleep pattern may be associated with polyphasic sleep; however, it is more often used to supplement normal sleep, especially when the sleeper has accumulated a sleep deficit.
Advocates of this sleep pattern recommend various durations for a power nap. Many have a precise time which they say is optimal; such claims are usually made without any scientific evidence. People who regularly take power naps usually have a good idea of what duration works best for them.
Some people take power naps out of necessity. For example, someone who doesn't get enough sleep at night and is drowsy at work may sleep during his or her lunch break. Others may prefer to regularly take power naps even if their schedule allows a full night's sleep.
In the Australian state of Victoria, the Transport Accident Commission has invested in advertising campaigns, advising drivers to take a "15 minute powernap" to help reduce the risk of fatigue when operating a motor vehicle.
In New York, a company called Metronaps has opened a branch in the Empire State Building, charging patrons US$14 for the use of facilities (semi-enclosed 'capsule' lounge chairs) for a brief power nap. Patrons can also purchase membership for $65 per month.A NASA study[1] has found that while naps improve memory functions, they do not aid basic alertness.
