    Excerpt

    Read excerpt

    Welcome to Part 2 of our HPA-axis series!When I started planning this series, I thought we might spend some time looking at all the different body systems the HPA axis manages to get its little hands into. And we still might! But as I was working through the research, something else tickled my fancy: the common belief that chronic stress can cause autoimmune disease.If you’ve spent any amount of time in wellness spaces, you’ve probably heard some version of this. Stress causes inflammation. Chro
