Show notes
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.
