Sleep Metrics

Meaning

Quantifiable physiological data points used in clinical practice to objectively assess the quality, duration, and efficiency of an individual’s sleep patterns and cycles. These metrics include total sleep time, sleep latency, the percentage of time spent in REM and deep slow-wave sleep, and the number of arousals or disturbances per night. The clinical utility of these measurements is to provide a precise, data-driven basis for diagnosing sleep dysfunction and tailoring therapeutic interventions.
