Psoas, stress, and fear

If true, this could be a big factor in the growing level of anxiety I've experienced after I moved to a full-time teleworking position that, along with a fall or two, definitely contributed to my experiencing some mobility issues:

The muscle that is most central to our fight/flight response is the psoas. When we don’t respond, these stress hormones go unspent and become stored in the body. This can bring many health problems including insomnia, lowered immune system, anxiety, eating disorders, depression, and living in a constant state of fear or alert.

Because the psoas is so intimately involved in such basic physical and emotional reactions, a chronically tightened psoas continually signals your body that you’re in danger, eventually exhausting the adrenal glands and depleting the immune system. – Liz Koch, Author of The Psoas Book

Thanks to this, I'm off in search of some physical therapy to address an issue with one of the hip flexors that has been problematic for me.
