Deep Sleep Biometrics

Meaning

Deep Sleep Biometrics refers to the quantifiable physiological parameters that are precisely measured during the slow-wave sleep (SWS) stage, which is universally recognized as critical for physical restoration, peak growth hormone release, and robust memory consolidation. These key biometrics include delta wave activity on electroencephalography (EEG), heart rate variability (HRV), and specific core body temperature fluctuations. Analyzing these metrics provides a direct, objective window into the quality of central nervous system recovery and the efficacy of the essential nocturnal anabolic phase.
