Scientists agree that sleep is not just rest but an active time when the brain sorts and stores memories. Different sleep stages help with different types of memory. Deep sleep (slow-wave sleep) is crucial for factual memories, while REM sleep is important for emotional and procedural memories. Missing sleep disrupts these stages and damages the brain's memory networks.
