The Interplay of Resilience and Mental Toughness

This is a particular area of passion of mine. It's the subject of my next book. I've been for the last six months writing all about resilience 2.0, as you call it, physiological resilience. And one of the chapters will be on psychological resilience as well, but really going very, very deep in the science of the specific mechanisms that our physiology engages. So physiologically, when we do breath holding practices, there's many, many studies that actually show that we become more resistant to mental stress. We're altering the set points where our autonomic nervous system functions and the brain circuitry that processes stress and fear responses.
