Fear isn’t just a feeling — it’s a survival system hardwired into the brain. Neuroscientist Dr. Samantha Yammine explains how the amygdala triggers the fight or flight response and what that cascade of cortisol and adrenaline actually means for how we react, cope, and sometimes spiral.

In this episode, explore how fear functions as both a protective tool and a challenge to mental well-being. Dr. Yammine breaks down the biology behind anxiety and shows how understanding the brain can lead to more self-compassion. From survival instincts to emotional patterns, this conversation brings clarity to the science behind what scares us — and why that knowledge is power.
