{{See also|REM rebound}}SWS rebound is lengthening and increasing frequency and depth of [[wikipedia:Slow-wave_sleep|SWS]] sleep which occurs after periods of [[wikipedia:Sleep_deprivation|sleep deprivation]]. A longer duration of time spent in SWS, as well as a significant shortening of [[Scheduling overview#Sleep stages|NREM3]] and NREM4 latencies, are common signs of SWS rebound, as a study on a selective slow-wave sleep deprivation has shown.<ref name="swsd" />

The slow-wave sleep latency shortens, which is also known as SOSWS or sleep-onset SWS.

Normally, SWS only occurs around 20-30 minutes into a sleep cycle. However, during the process of SWS rebound, SWS latency shortens, meaning that the body reaches SWS sooner. This phenomenon is known as ''''sleep-onset SWS''', or '''SOSWS'''.
