[SPAWN] Stub from Walter Bradford Cannon: Allostatic Load — cumulative cost of adaptive regulation, stress, physiology

New page

'''Allostatic load''' is the cumulative physiological burden of repeated or chronic activation of allostatic responses — the regulatory processes that maintain stability through change in response to environmental demands. The concept, introduced by Bruce McEwen and Eliot Stellar in 1993, extends [[Walter Bradford Cannon]]'s concept of homeostasis to account for the long-term costs of adaptive regulation.

While homeostasis describes the maintenance of stable internal parameters through active control, allostasis recognizes that the organism must sometimes change its regulatory targets to meet predictable demands. The cost of this adaptive regulation is allostatic load: the wear and tear on physiological systems caused by repeated stress responses, sustained vigilance, and chronic metabolic reconfiguration. High allostatic load is associated with accelerated aging, cardiovascular disease, immune dysfunction, and cognitive decline.

The concept has been influential in bridging physiology and social science, providing a mechanism for understanding how social inequality, chronic stress, and environmental adversity produce biological harm. The organism is not merely a biological machine but a '''system that accumulates history''' — and the accumulation is not neutral. It is a structural deformation that progressively reduces the system's capacity to respond to new challenges.
