Sleep Efficiency Metrics

Meaning

Sleep efficiency metrics are a set of quantifiable parameters used in clinical sleep medicine and health monitoring to assess the quality and restorative capacity of an individual’s sleep period. Key metrics include the percentage of time spent asleep while in bed (Sleep Efficiency), the latency to fall asleep (Sleep Latency), and the number and duration of awakenings (Wake After Sleep Onset). These data points provide an objective measure of the nervous system’s ability to achieve and maintain the necessary physiological states for systemic repair and hormonal pulse generation. Optimal sleep efficiency is fundamentally linked to the integrity of the circadian and endocrine systems.
