High-Quality Sleep Cycles

Meaning

High-Quality Sleep Cycles refer to the successful and uninterrupted progression through the complete, predictable stages of non-REM (N1, N2, N3/Deep Sleep) and REM sleep, characterized by appropriate duration and architecture for restorative function. Achieving high quality means the cycles are not fragmented, and sufficient time is spent in the most restorative phases, particularly Slow-Wave Sleep and REM. This state is essential for metabolic regulation, cognitive function, emotional processing, and the pulsatile secretion of key anabolic hormones like Growth Hormone. Clinical interventions often target the environmental and physiological factors that inhibit the natural flow of these cycles.
