Ep. 648 High and Low Cortisol Explained with Dr. Erin Kinney

Today, I’m delighted to connect with Dr. Erin Kinney. She’s a naturopathic medicine doctor and the founder of the Kinney Clinic, which focuses on hormone replacement therapy, nutrition, adrenal health, thyroid, and lymphatic system issues. Dr. Kinney is also the stress reset expert and author of The Cortisol Cure.

In our conversation, we explore cortisol debt, how to recognize it through self-assessment, and why Dr. Kinney believes we need to change the narrative around stress. We discuss ways to modulate the autonomic nervous system, specifically the parasympathetic, the true drivers of low cortisol, including sleep and circadian rhythm disruption, overtraining without adequate recovery, nutrient depletion, chronic or stealth infections, and unresolved trauma. Dr. Kinney explains how Lyme disease, Epstein-Barr virus, and mold and mycotoxin exposure can contribute to more pronounced stress responses, and we examine the influence of caffeine, alcohol, and stimulants; calming supplements for stress and sleep; the gut-brain axis and gut immune dysfunction. Dr. Kinney also shares her preferred strategies to regulate cortisol easily and effectively.

Stay tuned for a truly enjoyable conversation with the delightful Dr. Kinney. Her book, The Cortisol Cure, is a great resource for anyone suffering from multiple stress-related issues.
