Biological and epigenetic markers of trauma

Exposure to trauma during childhood increases the risk of developing chronic illnesses such as heart disease and diabetes by 30%
Intergenerational trauma has been linked to increased levels of inflammation markers in descendants, contributing to chronic disease risks
Family history of trauma correlates with increased cortisol levels in children, indicating higher stress response

Biological and epigenetic markers of trauma Interpretation

These sobering statistics underscore how childhood trauma and intergenerational wounds not only leave emotional scars but also silently chart a biological course toward chronic illnesses, revealing that healing a family’s history may be just as crucial as treating its symptoms.

Intergenerational trauma and transmission mechanisms Interpretation

These staggering statistics reveal that trauma is not just a personal burden but a multigenerational epidemic, weaving its wounds into our DNA and communities—so much so that healing must become a collective, societal effort lest we perpetuate a cycle where trauma's legacy continues to shadow generations yet unborn.
