Welcome to the Heart Rate Variability Podcast! In this episode, Matt Bennett interviews Adrian Low about a fascinating paper combining workplace wellbeing with biofeedback and mindfulness techniques. They discuss how these practices contribute to overall health and stress management.

This week's episode spans nine studies — from biofeedback and cognitive performance to chronic parenting stress, leadership in VR, body composition, AI-powered hypertension detection, post-cardiac-procedure monitoring, academic burnout, and the question everyone keeps asking about 5G. Whether you're a practitioner, researcher, or someone tracking your own autonomic health, this episode offers some...

This week on This Week in Heart Rate Variability, we explore four studies that collectively challenge us to think more deeply about what autonomic function tells us — and what it doesn't tell us on its own. From addiction treatment to heart failure, adolescent fitness to chronic pain, this episode traces the threads connecting heart rate variability to some of the most pressing questions in clinic...

In this episode, Matt Bennett talks to Cameron Allen about his work in heart rate variability biofeedback and the benefits of biofeedback in virtual reality. 

This week's episode covers five studies spanning sleep medicine, transportation safety, signal complexity methodology, cardiac mortality prediction, and autonomic neuroscience in a rare genetic condition. Together, they reveal how much untapped information lives in the heart rate variability signal — and how rapidly the field is developing tools to access it. RESEARCH HIGHLIGHTS THIS WEEK 1. Can a...

This week's episode covers four peer-reviewed studies spanning machine learning feature selection, clinical epidemiology, wearable device validation, and real-world mobile health observation. Whether you are a clinician, researcher, coach, or practitioner, this episode has direct relevance for how you think about measuring and applying HRV in your work. RESEARCH HIGHLIGHTS THIS WEEK Adaptive Genet...

In this episode, Dr. Andrew Seely joins Matt Bennett to discuss his work with HRV in the ICU and health care. 

From the reliability of the tools we use to measure it, to a mathematical algorithm built in its image, to machine learning models that read stress from its patterns, to a clinical trial showing it shifts in response to music — this week's four studies reveal HRV science at its most wide-ranging. Whether you're a clinician, researcher, coach, or curious practitioner, this episode offers something...

This week's lineup takes HRV science somewhere it doesn't always go — into genetics labs, operating theaters, and the physiology of breath control. Five new peer-reviewed studies examine HRV biofeedback combined with mindfulness for long-term workplace stress, a genetic polymorphism that shapes athlete burnout risk, yoga's measurable impact on autonomic function, a novel method for detecting high-...

The LF/HF ratio has been a fixture in heart rate variability research for decades. In this episode, we take a close look at why it persists, what the evidence actually says it measures, and why it so often appears to be the metric that moves most dramatically—in studies and in consumer apps alike. The 1996 Task Force paper, which helped establish LF/HF as a field standard, was more cautious than i...

HRV, Stress, Spirituality, and the Body's Hidden Autonomic Life: 4 Studies Worth Your Time Heart rate variability research doesn't always stay neatly inside the cardiovascular system — and this week's episode is proof. From the psychological interior of hypertensive patients, to the anatomy of the vagus nerve in a clinical encounter with postprandial dysfunction, to the cutting edge of wearable bi...

This week on This Week in Heart Rate Variability, Matt Bennett covers five peer-reviewed studies that span the full breadth of HRV science — from a controlled laboratory experiment on fast-paced breathing to a neurointensive care unit monitoring study, with stops along the way at the gut microbiome, a drowsy driver detection system, and a case report on osteopathic treatment for postprandial dizzi...

This week on This Week in Heart Rate Variability, we cover seven studies that push the boundaries of where HRV science is being applied — from predicting cardiovascular events in asymptomatic adults to detecting anger using a wrist sensor, from modeling how blood pressure cascades through the brain to understanding what happens to a mother's nervous system when her baby is born too soon. We also c...

In this episode, Stephanie White joins Matt Bennett to discuss fascinating science related to heart health and HRV at the cellular level.

This episode of This Week in Heart Rate Variability takes four very different windows into the autonomic nervous system and finds a single coherent message: your HRV is tracking the full texture of your life, not just your sleep or your workouts. We look at which psychosocial job demands most damage parasympathetic tone, how COPD reshapes autonomic regulation over time, whether walking through nat...

In this episode, Stephan Streuber joins Matt Bennett to discuss the role heart rate variability played in his recent research and article  Remote collaboration in virtual reality induces physiological synchrony comparable to face-to-face interaction. Dr. Stephan Streuber holds a Diploma in Media Informatics from Harz University of Applied Sciences and a PhD in Neural and Behavioral Sciences from t...

Heart rate variability science is moving in several directions at once this week — deeper into neural mechanisms, broader across clinical populations, and more precise in its analytical tools. Episode 34 covers six studies ranging from a new graph-theory method for detecting sex differences in resting autonomic activity to the neural pathway behind a side effect affecting millions of patients on G...

Needles, Treadmills, Wearables, and Operating Rooms: Four Ways the Autonomic Nervous System Shows Up Where You Least Expect It This week's episode covers four studies across four completely different clinical domains — acupuncture, exercise physiology, sleep medicine, and urology — and finds the same thread running through them all: HRV as a window into autonomic regulation. Whether the stimulus i...

In this week’s episode of The Heart Rate Variability Podcast , we step away from our usual multi-paper review to focus on a singular, defining debate in the field: the current controversy surrounding Polyvagal Theory . Polyvagal Theory has profoundly shaped how clinicians, trauma survivors, and the HRV community understand the relationship between the nervous system, safety, and social engagement....

This week's edition of This Week in HRV examines nine new studies that push the boundaries of what heart rate variability can tell us — from the psychology lab to the emergency department, the running trail to the pediatric pain clinic. We explore whether HRV biofeedback's benefits are real or a placebo, what chaos theory reveals about your heartbeat during cognitive work, whether a cleared concus...

This week’s edition of This Week in HRV dives into ten fresh studies that illustrate how heart rate variability is being used to decode everything from the heat of the climate to the heat of a high-stakes police encounter. We explore how HRV acts as a mediator for pain, a predictor of cognitive decline in extreme temperatures, and even a marker for the "acute effects" of professional gaming. 1. Th...

In this episode, Matt Bennett talks to Stephanie White about her work to create an HRV database to guide future research and HRV interventions. As always, Stephanie brings her expertise and passion to the show!

This Week in HRV Edition explores five newly published studies that push the boundaries of how we measure, modulate, and apply heart rate variability. These papers cover a diverse range of topics, including novel non-linear metrics, the efficacy of mindfulness, the future of digital psychiatry, light-based vagal stimulation, and the management of performance anxiety in musicians. A central theme c...
