Resilience Index Metrics

Meaning

Resilience Index Metrics are a composite set of physiological and biochemical markers specifically designed to quantify an individual’s capacity to maintain or rapidly return to homeostatic balance following a physical, metabolic, or psychological stressor. These metrics move beyond static baseline measurements to assess dynamic functional reserve and adaptive capacity. Key components often include heart rate variability (HRV), recovery time from standardized exertion, and the magnitude of post-stress hormonal excursions, such as cortisol or DHEA. A high Resilience Index indicates robust systemic adaptability and lower allostatic load, correlating strongly with longevity and a youthful biological age.
