Slow Wave Sleep Metrics

Meaning

Quantifiable measurements, derived from polysomnography or advanced sleep tracking, that specifically assess the quantity, duration, and intensity of Non-Rapid Eye Movement (NREM) Stage 3 sleep, also known as deep sleep. These metrics typically include total SWS time, percentage of SWS in total sleep time, and the density of delta waves. Clinically, these are the most direct indicators of the physical and hormonal restorative capacity of sleep.
