Traumatic stress may affect DNA but psychotherapy may heal it, study

It’s long been known that traumatic stress isn’t good for us. Traumatic stress has been linked to an increased risk in developing numerous diseases, including cancer.

Researchers, who recently had their study published in Psychotherapy and Psychosomatics, found this link at the molecular level. They found that traumatic stress may induce DNA breakage, which is one of the reasons long-term unresolved stress can increase the risk of disease. This is the bad news.

The good news, however, is that the researchers also found that psychotherapy may heal this damage. So while traumatic stress can harm the body, the harm is reversible by reducing stress and addressing the behavioral issues that resulted from the trauma.

Their conclusions: “Our results show – for the first time in vivo – an association between traumatic stress and DNA breakage; they also demonstrate changes at the molecular level, i.e., the integrity of DNA, after psychotherapeutic interventions.”
