Subjective Alertness Metrics

Meaning

Subjective Alertness Metrics are quantitative self-reported measures used to assess an individual’s conscious state of vigilance, readiness, and cognitive engagement at a given point in time. These metrics rely on standardized psychometric scales and questionnaires to capture the felt experience of wakefulness, fatigue, and focus, providing a complementary perspective to objective physiological measurements. While subjective, these metrics are crucial for understanding the experiential quality of hormonal and neurological states, particularly in the context of wellness and performance optimization.
