Can Trauma Turn on Genes? Epigenetics & the Three-Hit Model Explained

I’m Dr. Leah Hollon, and today we’re exploring a powerful concept that can completely change the way you understand trauma and chronic disease.

If you’ve ever wondered why symptoms appear “out of nowhere,” or why a stressful event triggered anxiety, autoimmune issues, depression, or physical illness — this explanation may help you understand the deeper biological story.

In this video, we break down:
✨ How trauma becomes imprinted through epigenetics
✨ Why genes don’t “rule the day” — and how environment + thoughts influence biology
✨ The Three-Hit Theory — vulnerability, early hardship, and the final triggering event
✨ How emotions like gratitude, joy, and love can shift gene expression
✨ Why some people develop symptoms only after a major life event
✨ How trauma loops, rumination, and emotional states keep genes activated
✨ The role of post-traumatic growth (PTG) and how healing can change biology again

📘 This concept is also discussed in my book, Unwinding the Imprints of Disease: Transforming Intergenerational and Transgenerational Trauma.
