In a nutshell (the child’s song And the knee bone’s connected to the thigh bone… might come to mind):
Stress increases inflammation in the body; this causes the body to make more cortisol; making more cortisol taxes the adrenal glands- this can lead to blood sugar dysregulation; which may lead to insomnia, stubborn weight, digestive issues, joint pain, and a suppressed or fired up auto-immune response.
"A critical shift in medicine has been the recognition that many of the damaging diseases of slow accumulation can either be caused or made far worse by stress," writes Robert M. Sapolsky, author of the critically acclaimed Why Zebras Don't Get Ulcers. "Stress can wreak havoc with your metabolism, raise your blood pressure, burst your white blood cells, make you flatulent, ruin your sex life, and if that's not enough, possibly damage your brain."
