In this episode of Bulletproof Radio, I dive into an intriguing discussion about trauma with my guest, Rachel Yehuda, Ph.D. We touch on what her latest research is uncovering about the role epigenetics plays in trauma and how to identify signs of trauma in your own life. “Trauma affects everybody,” Rachel says. “Having a traumatic event will definitely change you in some way in terms of how you view the world.”Rachel is professor and vice-chair of Psychiatry and professor of Neuroscience at Icahn School of Medicine at Mount Sinai in New York. As the daughter of two holocaust survivors, Rachel has publicly stated that her family's history has led to an "unmistakable presence of the past living in me." This first-hand experience with the epigenetic potential of trauma led Rachel to the fields of psychology, trauma, and epigenetic research. She has authored more than 300 high-cited journal articles and book chapters and developed fascinating insights about risk and resilience.With her in-depth knowledge of PTSD and epigenetics, Rachel walks us through how our parents' traumas can be passed down through the generations and how those triggers that you're working on today may not have originated in your lifetime. "It's not just that you carry the genes of your parents,” Rachel says. “You carry their history. You carry a lot of the sum total of their experiences."We also discuss:The often misunderstood role that cortisol plays in the stress response and how this "stress-hormone" may be better identified as an anti-stress hormone.How previously banned drugs like MDMA, DMT, and psilocybin may hold therapeutic potential for people working through traumas, and the road ahead for research into these drugs. The importance of finding the right practitioner to work with you on traumas that you may experience or have emerge in your life. Enjoy!
