{{Main|SOSWS}}

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]].
