What is the Origin of Stress Resilience Allostasis?

This term integrates Selye's stress concept with Sterling and Eyer's allostasis model, focusing on the efficiency of the adaptation-recovery cycle rather than just the presence of stress. It is a measure of neuroendocrine adaptability.

What is the Mechanism of Stress Resilience Allostasis?

Effective resilience requires the adrenal glands to mount a sufficient cortisol response when needed, followed by rapid downregulation of the HPA axis once the stressor is removed. Chronic elevation or blunted responses indicate allostatic overload, where persistent cortisol exposure drives downstream endocrine dysregulation, such as insulin resistance or immune suppression.

Stress Resilience Allostasis ∞ Area

Stress Resilience Allostasis

Meaning

The dynamic physiological process by which the body maintains stability (allostasis) through appropriate and transient activation of stress response systems (HPA axis) followed by rapid, complete return to baseline. High resilience implies minimal wear-and-tear from necessary stress exposure.
