NREM Stage 3, accounting for 15-25% of total sleep, is the deepest of all sleep stages. This stage contains primarily [[Wikipedia:delta waves|delta waves]], which are high-amplitude and low-frequency. Hence, this stage is also known as slow-wave sleep (SWS). It is very difficult to wake up from this stage; attempts at doing so tend to result in [[Special:MyLanguage/sleep inertia|sleep inertia]] -- a period of intense grogginess and impaired cognitive function. This stage of sleep plays a critical role in the maintenance of the brain through the [[Wikipedia:Glymphatic system|glymphatic system]]. This process takes about 30 to 60 minutes of continuous NREM3 to complete, and could be hindered by schedules containing only short naps. | NREM Stage 3, accounting for 15-25% of total sleep, is the deepest of all sleep stages.
