Dr. Waj Hoda is a chiropractor at Totum Life Science who specializes in Dynamic Neuromuscular Stabilization (DNS) and the connection between breathing mechanics and injury prevention. He explains why most people breathe incorrectly, how shallow mouth breathing causes low back pain, and how retraining the diaphragm creates automatic spine stability without extra effort.Waj breaks down why nasal breathing produces nitric oxide that improves oxygenation, how the diaphragm creates intra-abdominal pressure that stabilizes the spine (the volleyball analogy), and why mouth breathing in children changes the shape of their jaw and increases anxiety. He explains how to assess your own breathing quality, why belly breathing cues are often wrong, how box breathing reduces acute pain and muscle guarding, and the simple 5-10 breath exercise done three times a day that retrains diaphragmatic function. This episode reveals why breathing is free medicine for chronic pain, performance, anxiety, and recovery.
