What is the Origin of Slow-Wave Sleep Integrity?

Combining "Slow-Wave Sleep" (the deepest sleep stage) with "Integrity" (the state of being whole and unimpaired). This term is standard in polysomnography and sleep medicine.

What is the Mechanism of Slow-Wave Sleep Integrity?

SWS is modulated by homeostatic sleep drive and the circadian rhythm, with adequate adenosine accumulation promoting entry into this stage. During SWS, the brain actively prunes synapses and facilitates Memory Consolidation Fidelity, while the pituitary releases restorative hormones. Any disruption, such as sleep apnea or light exposure, degrades SWS Integrity, thereby impeding hormonal and cognitive restoration.

Slow-Wave Sleep Integrity

Meaning

Slow-Wave Sleep Integrity (SWS Integrity) measures the quantity, depth, and continuity of Stage N3 non-REM sleep, characterized by high-amplitude, low-frequency delta brain waves. High integrity is indispensable for the consolidation of declarative memory, metabolic regulation, and the pulsatile release of anabolic hormones like Growth Hormone. It is a key biomarker for systemic recovery.
