Physiological Stress Resilience

Meaning

Physiological Stress Resilience is the intrinsic capacity of an organism to maintain or rapidly restore homeostatic balance following exposure to acute or chronic physical, metabolic, or psychological stressors. This resilience is a measure of the body’s adaptive reserve, reflecting the robust functionality of the Hypothalamic-Pituitary-Adrenal (HPA) axis, the Autonomic Nervous System (ANS), and the immune system. High resilience indicates an efficient, well-regulated stress response that minimizes allostatic load and protects against premature hormonal aging. It is a critical determinant of sustained healthspan.
