Allostasis

Shrink Definition

Allostasis is the process through which the brain and body achieve stability by actively adjusting to changing environmental demands rather than maintaining fixed internal conditions. Unlike homeostasis, which emphasizes stability, allostasis emphasizes adaptation. Health depends upon flexibility.

Plain language

Your body doesn't simply stay balanced. It changes its balance depending on what life demands.

Shrink Insight

Resilience isn't remaining unchanged. It's changing appropriately.

Why it matters

Allostasis explains: • chronic stress • resilience • burnout • recovery • adaptation • performance • aging Repeated adaptation without sufficient recovery contributes to physiological wear and tear.

Common misunderstanding

Stress responses aren't inherently harmful. Remaining in them too long often is.

Shrink Perspective

Adaptation without recovery eventually becomes exhaustion.

Shrink Reflection

Where have life's demands exceeded your opportunities for recovery?

Shrink Journal

Describe one area where you've been adapting continuously without restoring yourself.

Shrink Step

Schedule recovery with the same importance as productivity.

Shrink Minute

Adapt. Recover. Repeat.

Shrink Takeaway

Recovery completes adaptation.

Evidence summary

Allostasis, introduced by Peter Sterling and Joseph Eyer and expanded by Bruce McEwen, has become a central concept in neuroscience, stress physiology, and behavioral medicine.
