Episode 347 - The Insulin Sensitivity Playbook: The Breath and Diabetes with The Breathing Diabetic, Nick Heath

About this episode

Rob interviews Dr. Nick Heath about the impact of breathing techniques on diabetes management.

Rob welcomes Dr. Nick Heath—an atmospheric scientist living with type 1 diabetes for 27+ years and known online as “The Breathing Diabetic”—to explore how breathing can become a practical lever for living well with diabetes. Nick shares his diagnosis at age 11 and how his “second diagnosis” moment came in his mid-20s when nutrition changes improved his control and opened his mindset to other tools within his control. That curiosity eventually led him into breathwork, first through Wim Hof and then more deeply through Patrick McKeown’s The Oxygen Advantage, where the science around nasal breathing, slower breathing, and CO₂ tolerance clicked—followed by a noticeable improvement in his blood sugars after a few months of consistent practice. From there, the conversation gets tactical and evidence-driven: why breathing is uniquely powerful because it’s both autonomic and voluntary, how airflow through the nose can influence brain activity and calm states, and how slow breathing can improve markers tied to autonomic function (like heart rate variability and baroreflex sensitivity) that are often reduced in people with diabetes. Rob connects this to modern diabetes stress—constant…
