Dr. Joe Dituri, also known as "Dr. Deep Sea," spent 100 straight days living underwater and walked away with lower cholesterol, longer telomeres, and twice the stem cells, so I had to get him on to break down what hyperbaric oxygen actually does. In this episode, we cover why a focused 20-day protocol might move your health-span more than any supplement stack, how his deep and REM sleep nearly doubled, and the safety rules almost no home-chamber owner knows. It genuinely shifted how I run my own chambers, and it'll shift how you think about oxygen, pressure, and aging, too.
