Health Span Metrics

Meaning

Health Span Metrics are a set of quantifiable biological and functional parameters used to assess the period of life during which an individual is generally healthy, active, and free from debilitating chronic disease. Unlike mere lifespan, which measures total years lived, health span focuses on the quality of those years. These metrics typically include markers of metabolic health, cognitive function scores, physical performance indicators, and key biomarkers of cellular aging like telomere length or epigenetic clocks. Clinically, tracking these metrics provides a robust, objective measure of the success of longevity and wellness interventions.
