In this uplifting and deeply human episode of The Gravity Doctors, Dr. Brennan Spiegel (Cedars-Sinai gastroenterologist and author of PULL) and Dr. Lachlan Kent (cognitive scientist and theorist of Mental Gravity) sit down with Harmon Clarke, a patient-turned-researcher whose remarkable recovery story illuminates the future of biogravitational medicine.
From septic shock and 200 days in hospital to yoga teacher, breathwork practitioner, and health researcher, Harmon’s journey embodies resilience, creativity, and the healing power of re-engaging with gravity. Together, they explore how movement, inversions, virtual reality, and breathwork can transform pain and depression into buoyancy and balance — culminating in a spontaneous “Gravity Rap” that captures the spirit of the show.

Biogravitational Medicine is a holistic approach to maintaining health in both body and mind. It's like a toolkit where you can find what works for you and your particular situation. Here are our top ten that work for most people most of the time. (As always, consult a doctor for personalised medical advice before attempting anything that might pose a risk to your physical or mental health, or for treatment of acute or chronic conditions.

Dr Spiegel has written a book about gravitational health called 'Pull' on the wide ranging themes underpinning this podcast - gut health, mental gravity, serotonin, the inner ear, the body's pumps and tubes, the gravitostat, and many more. The hosts take a tour through the world of biogravitational medicine by telling the story of what inspired the book, where the science is heading, and how people can apply the principles in their daily lives.

You know the feeling you get in your belly when falling on a rollercoaster? Ever wondered why we get similar gut feelings when we're "falling" in love? In this episode, Brennan (a gastroenterologist) and Lachlan (a cognitive scientist) talk about how gravity shapes gastrointestinal function and what relation gut feelings have to physical and mental health. They discuss Brennan's viral scientific paper, "Gravity and the Gut: A Hypothesis of Irritable Bowel Syndrome" and Lachlan's breakthrough theory of the mind called "Mental Gravity", and the connections between their shared ideas. Conditions like IBS often lead to anxiety and depression, which are the mental equivalent of "falling" and having "fallen", and so they draw a connection between gut health, gut feelings, and mental health. Strap yourself in for a rollercoaster ride through the topsy-turvy world of gut feelings in both body and mind.
