[[wikipedia:REM_rebound|REM rebound]] is lengthening and increasing frequency and depth of [[wikipedia:Rapid_eye_movement_sleep|REM]] sleep which occurs after periods of [[wikipedia:Sleep_deprivation|sleep deprivation]]. When people have been prevented from experiencing REM, they take less time than usual to attain the REM state.<ref>Myers, David (2004). ''Psychology'' (7th ed.). New York: Worth Publishers. p. [https://archive.org/details/psychology07myer/page/276 276]. ISBN 0-7167-8595-1. Retrieved 2010-01-09. <q>0716785951</q></ref> When people are unable to obtain an adequate amount of REM sleep, the pressure to obtain REM sleep builds up. When the subject is able to sleep, they will spend a higher percentage of the night in REM sleep.<ref>Carlson, Neil R. (2013). ''Physiology of behavior'' (11th ed.). Boston: Pearson. ISBN 9780205239399.</ref>
== SOREM ==
Polyphasic schedules, which reduce sleep hours, often rely on the REM rebound mechanism, which is an abnormally rapid transition from wakefulness to REM sleep, skipping the period of non-REM sleep that normally characterizes the beginning of the sleep period.<ref>(2009) Sleep-onset REM Period. In: Binder M.D., Hirokawa N., Windhorst U. (eds) Encyclopedia of Neuroscience. Springer, Berlin, Heidelberg. https://doi.org/10.1007/978-3-540-29678-2_5445 </ref> After REM debt is accumulated enough, it's common to have SOREM in the beginning of [[naps]] or [[cores]], especially close to the REM peak during the dawn hours, which is done by brain to alleviate REM pressure. SOREM is also common for [[wikipedia:Hypersomnia|hypersomniac]] and [[wikipedia:Narcolepsy|narcoleptic]] patients, who generally have excessive REM requirements.
