SWS rebound is lengthening and increasing frequency and depth of SWS sleep which occurs after periods of sleep deprivation. A longer duration of time spent in SWS, as well as a significant shortening of NREM3 and NREM4 latencies, are common signs of SWS rebound, as a study on a selective slow-wave sleep deprivation has shown.[1]
Sleep-onset SWS
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 sleep cycles in core(-s), rarely cause significant SWS loss. SOSWS is more common for extreme schedules, such as the nap-only line. This mechanism causes entering SWS almost immediately, which allows to get SWS-filled naps.
