Various Stages of Sleep Cycle

Choe et al. (2011) stated that sleep cycle consists of several phases throughout the night including two broad types that are Rapid Eye Movement(REM) sleep where most people dream and Non Rapid Eye Movement(NREM) sleep. The REM sleep is the last stage in sleep cycle which is when a person is dreaming. As for NREM sleep phase, it is further developed into N1, N2 and N3 where this N3 is also referred to the deep sleep phase, which is the main key for people waking up feeling refreshed and restored(Iber, 2007). As per Ackerman (2012), there are 5 stages of sleep cycle with each sleep cycle duration of 90 minutes each; Stages 1 and 2 are considered "light" sleep, while stages 3 and 4 are "deep" sleep. Conjunctionally, the 5th stage is REM (rapid eye movement) sleep, which is dreaming. "The deep sleep is a phase of sleep during which the arousal threshold to external stimuli is maximal"(Rechtschaffen, 1966). Zaman(2001)
