The slow-wave sleep latency shortens, which is also known as SOSWS or sleep-onset SWS. Generally polyphasic sleep schedules, which contain at least 3 full [[wikipedia:Sleep_cycle|sleep cycles]] in [[Cores|core(-s)]], rarely cause significant SWS loss. SOSWS is more common for extreme schedules, such as the [[Nap only|nap-only]] line. This mechanism causes entering SWS almost immediately, which allows to get SWS-filled [[naps]].

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'''.

SWS (Slow-wave sleep) rebound is the lengthening and increase in frequency and depth of SWS after periods of sleep deprivation. A longer duration of time spent in SWS, as well as a significant shortening of NREM3 latency are common signs of an SWS rebound, as a study on a selective slow-wave sleep deprivation has shown.[1]

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.
