In this monologue, Jake Burhans explains that repeatedly entertaining fearful thoughts chemically conditions the body. The hormonal sites that release the 'fear chemical' (likely cortisol or adrenaline) adapt to require larger amounts, similar to how a coffee drinker builds tolerance and needs more caffeine for the same effect. As the body demands more fear chemical, it signals the brain to generate more fear‑related thoughts, creating a self‑reinforcing feedback loop that makes fear difficult to break. The core message is that this physiological loop underlies the persistence of fear and explains why changing fearful thinking patterns can feel especially hard.
