Deep Sleep Cycles

Meaning

Deep Sleep Cycles, scientifically known as slow-wave sleep (SWS) or non-REM (NREM) stage 3, represent the most restorative phase of the sleep architecture, characterized by high-amplitude, low-frequency delta brain waves. This stage is fundamentally important for metabolic regulation, cognitive consolidation, and the pulsatile secretion of key anabolic hormones. The integrity of these cycles is essential for maintaining a robust endocrine system, facilitating the peak release of Growth Hormone (GH) and promoting tissue repair.
