1. what is the relationship between stress and illness?

Severe and prolonged stress can lead to tissue damage in our body and disease.

After going through a stressful episode there is a cascade of events that alter the nervous, cardiovascular, endocrine and immune systems. These changes are usually adaptive, at least in the short term. Stress hormones are produced by the nervous system and the hypothalamus-pituitary-adrenal axis.

At the same time these same mechanisms cause a constriction of the vasculature.

The result is harmful changes in the body and body that can cause many illnesses such as high blood pressure, pain, panic attacks, as well as other illnesses.
