Rachel Yehuda: Is Trauma a Disorder or a Survival Skill?

In this episode, Trevor and Eugene unpack intergenerational trauma with psychiatrist Rachel Yehuda. Turns out, trauma is inherited, passed down through generations, but don’t fear! The three turn the heavy science of PTSD into a profound conversation about meaning-making and we learn that where trauma can be passed-down, so can resilience. SurveyMonkey takes the fear out of asking—and the doubt out of deciding. If you haven't already....

In this episode of What Now? With Trevor Noah, featuring Trevor Noah and Dr. Rachel Yehuda, Rachel Yehuda: Is Trauma a Disorder or a Survival Skill? explores trauma as adaptive biology shaped by community, genes, and healing PTSD is debated as a “disorder” versus a normal, adaptive survival response that fails to switch off when safety isn’t restored.
