Physiological Adaptation

Meaning

Physiological Adaptation is the dynamic process by which the human organism undergoes reversible structural or functional changes in response to persistent environmental or internal stimuli, aiming to restore or maintain homeostatic balance. This mechanism is fundamental to survival and health, enabling the body to tolerate stress, optimize energy utilization, and enhance performance. Clinically, a robust capacity for adaptation is a key indicator of resilience and overall vitality, while a failure to adapt leads to allostatic load and pathology. This response is often mediated by neuroendocrine adjustments.
