Allostasis (al-uh-STAY-sis) (noun): The process by which your body achieves stability through change—especially in response to stress or environmental demands.

“Allostasis is the body’s way of anticipating needs and preparing to meet them before they arise, keeping us dynamically balanced in a changing world.”

— Dr. Nadine Burke Harris, The Deepest Well

Published January 1, 2018

In The Deepest Well, pediatrician and health advocate Nadine Burke Harris explores how childhood trauma and chronic stress impact our physical and mental health over a lifetime. She shows how allostasis helps the body adapt but can also lead to wear and tear.

SMARTER INSIGHT
Allostasis isn’t just about reacting—it’s about proactive adaptation. When stress becomes chronic, allostasis can strain the body, influencing everything from immunity to brain function.

USE IT TODAY
Think about a stress you’ve managed recently. How did your body prepare or respond ahead of time? Small steps like mindfulness or adequate rest can support healthy allostatic balance.
