Psychologist reveals self-harm produces cocaine-like endorphins that soothe trauma survivors

About this episode

In this intimate psychological exploration, a trauma expert defines trauma through three core components—violation, powerlessness, and shame—while illustrating how seemingly minor childhood experiences can leave lasting imprints. The psychologist, speaking with the host, explains that trauma occurs when life's fundamental goodness is violated, whether through severe abuse or childhood bullying, and that powerlessness to change the situation intensifies its impact. The conversation takes a deeply personal turn when the host reveals a vivid memory of shame from grade six involving a girl's disgusted reaction to his nail-biting, which the expert validates as genuine trauma. The episode's most striking revelation concerns the biochemistry of self-harm: behaviors ranging from nail-biting to cutting trigger endorphin production at levels comparable to cocaine, offering biochemical relief from stress hormones like cortisol and adrenaline. The expert reframes self-soothing behaviors through this lens, explaining that when people cannot manage trauma-induced stress through healthy means, the body resorts to self-harm to produce its own opioid-like compounds. Both the host and psychologist acknowledge their own histories with these behaviors, creating an unusually vulnerable exchange that humanizes clinical concepts. The discussion emphasizes that trauma's effects are not determined by objective severity but by the subjective experience of violation, the inability to restore safety, and the resulting internalized belief that something is fundamentally wrong with oneself.
