Episode Details

Have you ever gotten stronger from something that should have damaged you? Today we explore the hormesis curve—the counterintuitive principle that the thing damaging you is the same thing making you stronger, split by an invisible line. We dig into overtraining syndrome, why mainstream science suppressed this concept for a century, and how to find that sweet spot between adaptation and systematic breakdown. 00:00 - Opening: The Paradox of Beneficial Damage 02:30 - What is the Hormesis Curve? 05:00 - The Graph Explained: Stress, Adaptation & the Breaking Point 08:30 - History: Why Science Rejected Hormesis (Calabrese & the Suppression) 14:00 - Finding Your Personal Sweet Spot --- Sources & further reading: • Hans Selye — "A Syndrome Produced by Diverse Nocuous Agents" (letter to Nature, 1936) — (original letter) • Edward Calabrese — "Hormesis: a revolution in toxicology, risk assessment and medicine": https://pmc.ncbi.nlm.nih.gov/articles/PMC1299203/ • Bruce McEwen — "Stress, Adaptation, and Disease: Allostasis and Allostatic Load" (Annals of the New York Academy of Sciences, 1998): https://nyaspubs.onlinelibrary.wiley.com/doi/10.1111/j.1749-6632.1998.tb09546.x • Cadegiani & Kater — "Novel causes and consequences of overtraining syndrome: the EROS-DISRUPTORS study": https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6751688/ • Cadegiani & Kater — "Hypothalamic-Pituitary-Adrenal (HPA) Axis Functioning in Overtraining Syndrome" (EROS-HPA Axis): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5722782/ • Szoke et al. — "Hormonal aspects of overtraining syndrome: a systematic review": https://pmc.ncbi.nlm.nih.gov/articles/PMC5541747/ • Cadegiani & Kater — "Effects of Overtraining Status on the Cortisol Awakening Response" (EROS-CAR): https://pubmed.ncbi.nlm.nih.gov/33662935/ • Kreher & Schwartz — "Overtraining Syndrome" (overview, ScienceDirect): https://www.sciencedirect.com/topics/medicine-and-dentistry/overtraining-syndrome • Rattan — "Stress-Response Hormesis and Aging" (Cell Metabolism, 2008): https://www.sciencedirect.com/science/article/pii/S1550413108000028 • Jackson — "Evaluating the Role of Hans Selye in the Modern History of Stress" (NCBI Bookshelf): https://www.ncbi.nlm.nih.gov/books/NBK349158/ • Calabrese — "Paradigm lost, paradigm found: The re-emergence of hormesis": https://www.sciencedirect.com/science/article/abs/pii/S0269749104003987 • Kendig et al. — "Defining Hormesis" (International Journal of Toxicology, 2010): https://journals.sagepub.com/doi/10.1177/1091581810363012 • Frontiers — "Overtraining Syndrome as a Complex Systems Phenomenon": https://www.frontiersin.org/journals/network-physiology/articles/10.3389/fnetp.2021.794392/full • Wang et al. — "Current advances and future trends of hormesis in disease" (npj Aging, 2024): https://www.nature.com/articles/s41514-024-00155-3 • Calabrese & Mattson — "How does hormesis impact biology, toxicology, and medicine?"
