Keeping Abreast with Dr. Jenn 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 underwater
- How hyperbaric oxygen therapy impacts inflammation, immune function, sleep, and aging
- The difference between biological age vs. chronological age and why it matters.
- Why muscle and bone health are critical pillars of longevity
- How healthy stress can strengthen the brain, body, and immune system
- The science behind collagen synthesis, stem cells, and tissue repair
- What the research actually says about hyperbaric medicine and cancer
- How to identify qualified, safe hyperbaric centers and avoid poorly run facilities
