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 facilities Episode Timeline Highlights: 00:00 Introduction to Dr. Joe Dituri and His Mission 03:08 What Hyperbaric Medicine Is and How It Works 05:54 Why He Chose to Live Underwater for 100 Days 08:54 Daily Life, Work, and Challenges Beneath the Ocean 11:53 Sleep, Brain Function, and Cognitive Changes Under Pressure 14:53 Inflammation, Telomeres, and Measuring Cellular Health 18:05 The Core Science Behind Hyperbaric Oxygen Therapy 28:50 Isolation, Connection, and Human Biology 33:49 Biological Age vs. Chronological Age 50:35 Hyperbaric Therapy for Health Optimization 53:17 Collagen, Tissue Healing, and Regeneration 56:07 Hyperbaric Medicine and Cancer Support 01:06:50 Treatment Frequency, Duration, and Expectations 01:12:03 How to Find Safe and Qualified Hyperbaric Centers 01:15:52 Longevity, Optimization, and What’s Next Where to Find Dr. Joseph Dituri (Dr. DeepSea) Website: https://drdeepsea.com/ Instagram: www.instagram.com/drdeepsea To talk to a member of Dr. Jenn's team and learn more about working privately with RHMD, visit: https://jennsimmons.simplero.com/page/377266?kuid=327aca17-5135-44cf-9210-c0b77a56e26d&kref=vOKy0sAiorrK To get your copy of Dr. Jenn's book, The Smart Woman's Guide to Breast Cancer, visit: https://tinyurl.com/SmartWomansBreastCancerGuide To purchase the auria breast cancer screening test go here https://auria.care/ and use the code DRJENN20 for 20% Off.
