Anxiety Comes From the Amygdala

Anxiety isn’t a personal failure; it’s a brain-based survival response. In this episode of The Hidden Why Podcast, Leigh Martinuzzi sits down with clinical psychologist and neuroscientist Dr. Catherine Pittman, co-author of Rewire Your Anxious Brain, to explore what’s really happening in the brain when we experience anxiety, panic, and fear.

Dr. Pittman explains the powerful role of the amygdala, how it learns through experience, why it reacts before we can think, and how modern life keeps it on high alert. Together, they unpack why anxiety feels so real, even when the danger isn’t, and what we can do to calm the brain using practical, science-backed strategies like movement, sleep, breathing, and meditation.

This episode offers clarity, compassion, and tools for anyone who struggles with anxiety or wants to understand it better.
