Dr. M’s Women and Children First Podcast #69 – Stephen Porges, Ph.D. – Polyvagal Theory

This week I sit down with Dr. Stephen Porges,
He is a Distinguished University Scientist at Indiana University where he is the founding director of the Traumatic Stress Research Consortium. He is Professor of Psychiatry at the University of North Carolina, and Professor Emeritus at both the University of Illinois at Chicago and the University of Maryland.
He served as president of the Society for Psychophysiological Research and the Federation of Associations in Behavioral & Brain Sciences and is a former recipient of a National Institute of Mental Health Research Scientist Development Award. He has published more than 400 peer-reviewed papers across several disciplines including anesthesiology, biomedical engineering, critical care medicine, ergonomics, exercise physiology, gerontology, neurology, neuroscience, obstetrics, pediatrics, psychiatry, psychology, psychometrics, space medicine, and substance abuse. In 1994 he proposed the Polyvagal Theory, a theory that links the evolution of the mammalian autonomic nervous system to social behavior and emphasizes the importance of physiological state in the expression of behavioral problems and psychiatric disorders. The theory is leading to innovative treatments based on insights into the mechanisms mediating symptoms observed in several behavioral, psychiatric, and physical disorders.
He is the author of multiple books on his Polyvagal Theory: including the Neurophysiological foundations of Emotions, Attachment, Communication, and Self-regulation, as well as Polyvagal Safety: Attachment, Communication, Self-Regulation. His newest book cowritten with his son is called Our Polyvagal World, How Safety and Trauma Change Us. Dr. Porges is the creator of a music-based intervention, the Safe and Sound Protocol ™ (SSP), which is used by therapists to improve social engagement, language processing, and state regulation, as well as to reduce hearing sensitivities.
This is such a fascinating conversation. He brings the worlds of psychiatry and anthropological physiology into union for us to understand the why of trauma reactions and the future unwinding that is now possible. This is a must listen to conversation if you know anyone with trauma history.
Please enjoy my conversation with Professor Porges,

Dr. M’s SPA Newsletter Audiocast Volume 14 Issue 12

Pregnancy is a super important time. Do not take by inhalation, ingestion or other exposure anything that is a potential toxin for the body.
Things to avoid:
1) Caffeine – in low to minimal doses, it is clear that caffeine is safe for pregnant women and their offspring. Caffeine easily crosses into the placenta and thus the baby’s circulation. In utero babies cannot metabolize caffeine well putting them at risk with increasing exposure. The data does not support the same reality for more moderate to high doses. Caffeine is known to raise blood pressure and heart rate in all users in variable numbers based on metabolism capabilities…… plus a literature review and a recipe.

Literature Review
1) Cancer is now a unique risk factor for Cardiovascular disease according to recent research. This is being discussed as a point of emphasis for those that have been diagnosed with cancer as the knowledge is a wake up alarm to the biological underpinnings of these disparate immune based diseases. (Melchiori R. et. al. 2023) If you have a strong family history of cancer and heart disease as I do, this data needs to be understood for a prevention lens focus. In a few weeksx I will be discussing APOE genotypes for understanding these realities.
2) In a translational model, sulphurophane increases mitochondrial biogenesis…..Plus a continuous glucose monitor experiment and more from Alison Gopnik’s book.

Literature Review
1) In an excellent paper by Dr. Harlan and colleagues, we see a group looking at how to modify ultra processed foods to remain tasty for consumption but also healthy. The lead author is Dr. Rob Lustig, a pioneering Pediatric Endocrinologist from UCSF and upcoming podcast guest. From the paper: “Ultraprocessed food is established as a metabolic disruptor acting to increase adiposity, reduce mitochondrial efficiency, drive insulin resistance, alter growth, and contribute to human morbidity and mortality. Consumer packaged goods (CPG) companies are beginning to understand the detrimental impact of the food they market, and have employed substitution strategies to reduce salt, sugar, and fat. However, the harms of ultraprocessed foods are far more complex than any single component, and are not ameliorated by such simple substitutions.” (Harlan et. al. 2023)……as well as information on Why ask why? and a recipe of the week.

Literature Reviews have been very popular. Thus, 2024 will start with science update.

1) Time restricted eating patterns are known to help physiology and metabolism by initiating a pause in the action of mTOR and muscle synthesis as well as inducing autophagy. Autophagy is critical to the clearance of broken or damaged cells following injury or disease. How does circadian biology play into this reality? From Cell Metabolism: “Circadian disruptions impact nearly all people with Alzheimer’s disease….plus a discussion on water, dehydration and prevention as well as a recipe of the week.

Literature Review
1) High resting cardiac vagal tone or control, CVC, is associated with more flexible emotional responding to external stressful stimuli. With regard to vagal changes the evidence shows us that stress will decrease CVC . (Balzarotti et. al. 2017)
Being relaxed and not stressed out is always associated with better cellular physiology. CVC is a marker of relaxation and thus emotional control. Whenever you find yourself emotionally dysregulated, there is a good chance that your vagal tone is off. Work to meditate, exercise and relax which will increase CVC and help you cope.
2) Continuing on the same theme….. plus a discussion on maternal neural hormonal rewiring, and a recipe of the week.

Literature Review
1) Pericytes are critical cells that sit around the tiny blood vessels called capillaries of the body especially in the brain. They are involved in regulating blood vessel activity. They communicate directly with the endothelial cells making them super important in the activity of the blood vessel and metabolism at the local tissue interface. From the journal Cell Death and Disease we see: “Crosstalk mechanisms….And some other discussions on Cancer detection at physicals as well as the recipe of the week.
