BITESIZE | How To Become Less Reactive & Cultivate A Deep Sense Of Calm | Jonny Miller #653

In this Bite Size episode of Feel Better, Live More, Dr. Rangan Chatterjee explores the science of nervous system regulation with guest Jonny Miller, founder of Nervous System Mastery. The conversation centers on how chronic stress reshapes our perception of reality, making us more reactive, anxious, and disconnected. Miller explains that our nervous system acts as a lens through which we experience the world, and when dysregulated, it leads to symptoms like fatigue, sleep issues, relationship struggles, and burnout—what he describes as a 'feather, brick, dump truck' progression. He emphasizes that anxiety isn't an emotion itself but a physiological response to suppressed emotions, and that emotions typically last only 10–20 seconds unless we resist them. The key to lasting calm lies not in suppressing reactivity, but in developing interoception, practicing bottom-up techniques like breathwork and somatic awareness, and allowing emotions to fully process—just like the impala that shakes off stress after escaping a predator. The episode concludes with the powerful idea that physical movement may help complete unprocessed stress responses, restoring energy and emotional resilience.
