Sleep Architecture Sequencing

Meaning

Sleep architecture sequencing refers to the precise, predictable pattern and duration of the cyclical progression through the different stages of sleep: NREM Stage 1, NREM Stage 2, slow-wave sleep (NREM Stage 3), and REM sleep. This sequence is not random; it follows a specific, approximately 90-minute cycle that repeats multiple times throughout the night. Optimal sequencing is essential for maximizing the restorative functions associated with each stage, including memory consolidation and hormonal release. Disruptions compromise systemic recovery.
