During the first year of life, infants spend most of their time sleeping. An infant can go through several periods of change in sleep patterns. These can start at 1 week, occurring weekly or fortnightly, until 8 years of age due to innate and external factors that contribute to sleep. [3]
7 week old infant in active sleep. Infant sleep in the first year can be categorised into active sleep (AS) and quiet sleep (QS). Active sleep is similar to the adult REM sleep in that it is characterised by eye and other kinds of movement; however, unlike adults in REM, infants tend to enter AS at the beginning of their sleep cycle, as opposed ...
Napping behavior during daytime hours is the simplest form of polyphasic sleep, especially when the naps are taken on a daily basis. The term polyphasic sleep was first used in the early 20th century by psychologist J. S. Szymanski, who observed daily fluctuations in activity patterns. [2] It does not imply any particular sleep schedule.
He is best known for his work in the field of sleep research, specifically the relationship between sleep and performance. He is best known for coining the term "power nap". [1] He holds a B.A. from Williams College and an M.A. and Ph.D. from Cornell University. Maas has also produced numerous film specials on sleep research for PBS, BBC, and ...
Sleep hygiene studies use different sets of sleep hygiene recommendations, [15] and the evidence that improving sleep hygiene improves sleep quality is weak and inconclusive as of 2014. [2] Most research on sleep hygiene principles has been conducted in clinical settings, and there is a need for more research on non-clinical populations.
A power nap, also known as a Stage 2 nap, is a short slumber of 20 minutes or less which terminates before the occurrence of deep slow-wave sleep, intended to quickly revitalize the napper. The expression "power nap" was coined by Cornell University social psychologist James Maas. [2] The 20-minute nap increases alertness and motor skills. [2]
A nap is a form of biphasic or polyphasic sleep, where the latter terms also include longer periods of sleep in addition to one period. For years, scientists have been investigating the benefits of napping, including the 30-minute nap as well as sleep durations of 1–2 hours. Performance across a wide range of cognitive processes has been ...
Why We Nap: Evolution, Chronobiology, and Functions of Polyphasic and Ultrashort Sleep is a 1992 book edited by Claudio Stampi, sole proprietor of the Chronobiology Research Institute. It is frequently mentioned by " polyphasic sleepers ", as it is one of the few published books about the subject of systematic short napping in extreme ...
