Anxiety is not just a feeling — it is a pattern of activity in the brain. Dr. Michael Newman explains how anxiety involves hyperactivity in the amygdala, dysregulated cortisol levels, and weakened communication between emotional and rational brain centers. He explores how exercise can biologically rewire these pathways, promoting neuroplasticity, reducing stress hormones, and strengthening emotional regulation.

Addiction isn’t a character flaw — it’s a pattern written in the brain. But the same brain that addiction rewires can also heal. Understanding this changes how we treat substance use disorder, how we support recovery, and how we see ourselves.
