A category of clinical and lifestyle strategies, grounded in the scientific study of aging (geroscience), designed to extend healthspan—the period of life spent in good health—and potentially lifespan. These interventions target the molecular and cellular hallmarks of aging, such as genomic instability, telomere attrition, and mitochondrial dysfunction. Examples include specific pharmacological agents, advanced nutritional protocols, and hormone optimization therapies. The primary focus is on preventative medicine and enhancing biological resilience against age-related decline.
Origin
The term arises from the burgeoning field of longevity science, which seeks to translate fundamental biological discoveries about aging into actionable human health strategies. The use of “interventions” emphasizes the proactive, clinical application of this research, moving beyond mere observation to active physiological modulation. This represents a paradigm shift in age management.
Mechanism
Longevity interventions function by modulating key signaling pathways that regulate cellular stress response and repair, such as mTOR, AMPK, and sirtuins. Nutritional strategies like caloric restriction or intermittent fasting activate stress response pathways that enhance cellular cleanup (autophagy) and repair mechanisms. Pharmacological agents may target senescent cells or enhance NAD+ availability, collectively aiming to stabilize the epigenome, maintain mitochondrial function, and restore youthful cellular function.
