127: What 100 Days Underwater Revealed About Aging and Healing with Dr. Joseph Dituri

In this episode of Keeping Abreast, Dr. Jenn Simmons sits down with Dr. Joseph Dituri, a biomedical engineer, hyperbaric medicine specialist, and former U.S. Navy saturation diver, to explore the science of healing, aging, and human resilience.Drawing from his clinical work in hyperbaric medicine and his recovery from a traumatic brain injury, Dr. Dituri explains how oxygen, pressure, and controlled physiological stress affect inflammation, sleep quality, immune function, and cellular repair. Together, they examine the evidence behind biological versus chronological age, the role of muscle and bone health in longevity, and the evolving, evidence-informed use of hyperbaric oxygen therapy in healing and cancer support. In This Episode, You'll Learn:What happens to the human body when it lives under pressure for 100 days underwaterHow hyperbaric oxygen therapy impacts inflammation, immune function, sleep, and agingThe difference between biological age vs. chronological age and why it matters.Why muscle and bone health are critical pillars of longevityHow healthy stress can strengthen the brain, body, and immune systemThe science behind collagen synthesis, stem cells, and tissue repairWhat the research actually says about hyperbaric medicine and cancerHow to identify qualified, safe hyperbaric centers and avoid poorly run facilitiesEpisode Timeline Highlights:00:00 Introduction to Dr. Joe Dituri and His Mission03:08 What Hyperbaric Medicine Is and How It Works05:54 Why He Chose to Live Underwater for 100 Days08:54 Daily Life, Work, and Challenges Beneath the Ocean11:53 Sleep, Brain Function, and Cognitive Changes Under Pressure14:53 Inflammation, Telomeres, and Measuring Cellular Health18:05 The Core Science Behind Hyperbaric Oxygen Therapy28:50 Isolation, Connection, and Human Biology33:49 Biological Age vs. Chronological Age50:35 Hyperbaric Therapy for Health Optimization53:17 Collagen, Tissue Healing, and Regeneration56:07 Hyperbaric Medicine and Cancer Support01:06:50 Treatment Frequency, Duration, and Expectations01:12:03 How to Find Safe and Qualified Hyperbaric Centers01:15:52 Longevity, Optimization, and What’s NextWhere to Find Dr. Joseph Dituri (Dr. DeepSea)Website: https://drdeepsea.com/Instagram: www.instagram.com/drdeepseaTo talk to a member of Dr. Jenn's team and learn more about working privately with Dr. Jenn visit: https://calendly.com/stephanie-1031/clarity-callTo get your copy of Dr. Jenn's book, The Smart Woman's Guide to Breast Cancer, visit: https://tinyurl.com/SmartWomansBreastCancerGuideTo purchase the auria breast cancer screening test go here https://auria.care/ and use the code DRJENN20 for 20% Off.Connect with Dr. Jenn:Website: https://www.jennsimmonsmd.com/Facebook: https://www.facebook.com/DrJennSimmonsInstagram: https://www.instagram.com/drjennsimmons/YouTube: https://www.youtube.com/@dr.jennsimmons
