The practice of immersing your body in ice water is growing in popularity based on claims of improved mood and well-being, muscle recovery after exercise, even longevity. But this ignores the well-established fact that sudden cardiac death is a real risk due to coronary spasm, causing heart attack, and unstable heart rhythms due to a situation called autonomic conflict. There are a growing number of lawsuits that have been filed for the many sudden cardiac deaths that have occurred. So let’s discuss what we know about this concept of cold water immersion and why it is such a dangerous practice. • Immersion in water around 15°C/60°F triggers dangerous physiological responses• Cold exposure causes coronary arteries to spasm, potentially leading to heart attack• Most adults have some degree of endothelial dysfunction, making them vulnerable• "Autonomic conflict" occurs when both nervous system branches activate simultaneously• Multiple lawsuits have been filed over deaths from ice baths and polar plunges• Safer alternatives exist for achieving the claimed benefits of cold exposure• Cold showering (starting warm and gradually cooling) may offer similar benefits with less risk________________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._____________________________________________________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport the showYouTube channel: https://www.youtube.com/@WilliamDavisMD Blog: WilliamDavisMD.com Membership website for two-way Zoom group meetings: InnerCircle.DrDavisInfiniteHealth.com Books: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed
