Biological Clock Speed

Meaning

Biological Clock Speed is a conceptual term referring to the overall rate at which an individual’s intrinsic biological processes, including cellular turnover, metabolic rate, and telomere shortening, progress over time. This speed is not fixed but reflects the accumulated impact of genetics, lifestyle, and environmental stressors on the body’s physiological age, often differing significantly from chronological age. A slower, optimized biological clock speed is clinically associated with enhanced longevity, greater resilience, and a reduced incidence of age-related disease. This metric provides a holistic view of systemic aging.
