Sustained Vitality Matrix

Meaning

This conceptual framework describes the integrated, dynamic equilibrium among key endocrine axes—adrenal, thyroid, and gonadal—that supports persistent high-level physiological function and resilience against chronic stress. Sustained vitality is achieved when the throughput and set points of these systems remain optimized over extended periods, preventing systemic burnout or functional decline. It is the holistic measure of endocrine endurance.
