The Resilient Engine with Dr. Jay Wiles
A show about the nervous system, human performance, and what the measurement industry keeps getting wrong. Dr. Jay T. Wiles is a clinical health and performance psychologist who has spent his career measuring physiology in high performers. Most of what circulates about nervous system health is noise, and most of what is being sold trains state change, which is transient, rather than trait change, which lasts. Solo episodes work through the model piece by piece: resonance, sleep, attention, load, and what the wearable on your wrist is and is not telling you. Interviews bring in the researchers and practitioners who...
HRV CV 101: Why a Stable HRV Beats a High One
Every wearable hands you one number in the morning and a traffic light to go with it. Most people check it daily and change nothing. Dr. Jay Wiles argues that is worse than not tracking at all: data without action is a waste of time, and a red light you cannot act on is one more source of stress.
This episode is about the number to watch instead. HRV CV, the coefficient of variation of heart rate variability, measures how steady your HRV stays across a rolling week rather than how high it reads on any one...
Resonance Breathing 101: Train Your HRV, Don't Chase It
Episode one argued that almost every nervous system technique being sold right now produces state change rather than trait change. This is the follow up, and it names the tool.
Resonance breathing is the practice Dr. Jay Wiles would keep if he had to give up every other one. It is also, strangely, the one almost nobody outside academic psychophysiology is teaching. Every popular nervous system creator will walk you through the physiological sigh, box breathing, or 4-7-8. Those are state tools. They answer the question of how to feel better in the next ninety seconds...
So Much Nervous System B.S....
Nervous system care has become a buzzword and most of what is circulating about it is wrong. Dr. Jay Wiles is a clinical health and performance psychologist who has spent his career measuring physiology in high performers, and this first episode is his case against the noise.
The core argument: almost every technique being sold right now produces state change, not trait change. State change is real and useful. It is what gets you back down after someone cuts you off in traffic. But it is transient, and there is little evidence that repeating it changes the...
