Physiological Resilience

Meaning

Physiological resilience is the inherent capacity of an organism to resist disruption, recover rapidly, and maintain stable function in the face of internal or external stressors, such as illness, injury, or psychological pressure. This robust adaptive capacity is a key indicator of biological youth and is heavily dependent on the integrity of the neuroendocrine and immune systems. A high degree of resilience translates clinically into a faster recovery time and a reduced susceptibility to chronic age-related diseases. Supporting and measuring this resilience is a core tenet of longevity medicine.
