If you wake up feeling tired and sluggish, you likely had poor or disrupted slow-wave sleep. The most important sleep stage for memory consolidation and overall sleep quality is slow-wave sleep (SWS). You get your deepest sleep during N3 sleep, which means this stage is crucial to waking up feeling well-rested and like you got a good night’s sleep.
