The Chemistry Problem: Why stress and burnout aren’t mindset problems

Welcome back!

In today’s episode, Stacey and Cade speak with executive coach and performance expert Jenny Evans about why stress and burnout are not just mindset problems, but deeply rooted in biology and chemistry.

Jenny explains how chronic stress triggers automatic chemical responses in the body that reduce access to the prefrontal cortex, shifting decision-making toward reactive, survival-based thinking. The conversation explores why traditional advice like “manage your mindset” only addresses symptoms, not root causes.

Key takeaways:

Stress is primarily a physiological and chemical process, not just a mindset issueDecision quality declines as energy depletes throughout the dayRecovery, not just effort, determines sustained performanceSmall “microbursts” of movement, breath, or focus can rapidly reset energy levelsDesigning environments to support habits reduces reliance on willpower
