Rachel Yehuda: The Biology of What We Carry

Podcast cover

What Now? with Trevor Noah

The podcast explores the biological aspects of trauma and PTSD, challenging the traditional view of trauma as solely a psychological phenomenon. Dr. Rachel Yehuda, a neuroscientist, discusses how trauma's effects can be observed in the body, such as through cortisol levels and amygdala activity. She highlights the debate around PTSD as a disorder versus a natural survival mechanism, and the importance of safe environments for healing. The conversation touches on intergenerational trauma, where sensitivities or biases are passed down, not specific memories. Yehuda also shares her evolving views on trauma treatment, including the potential of psychedelic-assisted therapy to foster self-compassion and forgiveness. The discussion emphasizes that trauma's impact extends beyond the individual, affecting communities and societies, and underscores the significance of resilience and empathy in navigating its effects.
