158. Dr. Kavin Mistry: Primal Health Design, Biological Aging, and Reconnecting with Human Biology
4/23/20261 hr 2 min
Modern life is quietly accelerating biological aging, from posture and movement patterns to sleep disruption, chronic stress, and constant digital stimulation. Many of the symptoms people experience daily, like pain, fatigue, brain fog, and disconnection, may reflect a deeper misalignment with how the human body was designed to function.
In this episode of Extend, I sit down with Dr. Kavin Mistry, board-certified neuroradiologist and author of Primal Health Design, to unpack how modern lifestyles are reshaping our biology and accelerating aging. We break down how posture, movement, circadian rhythm, nutrition, and environment influence brain and spine health, and why reconnecting with our primal design is essential for long-term resilience and performance.
We also explore how daily practices like morning sunlight, grounding, deep work, and intentional routines can help restore alignment with your biology and create more energy, clarity, and longevity in a fast-moving, AI-driven world.
Dr. Kavin Mistry is a board-certified neuroradiologist, author, and thought leader in longevity and human performance, known for developing the Primal Health Design framework to help individuals reconnect with their biology and reverse the hidden effects of modern living.

[gentle music] Welcome to Extend with me, Dr. Darshan Shah, a podcast dedicated to cutting-edge science, research, tools, and protocols designed to help you extend your health span. Having become one of the youngest doctors in the country at the age of 21, and trained and board-certified at the Mayo Clinic, I've accumulated three decades of practice as a board-certified surgeon and longevity expert. Over that time, I've discovered that a mere 20% of health knowledge yields 80% of the results when it comes to your health span. We are living in a new era where we are creating a new healthcare system no longer focused on disease management, but achieving optimal health and vitality. Join me as I interview world-renowned experts offering you a step-by-step guide to proactively avoid disease and, most importantly, extend your health span. [gentle music] Modern life is pulling us further and further away from the way our human bodies were designed to live. From tech neck and low back pain to poor sleep, distraction, loneliness, and disconnection from nature, all of these things that we do day to day that we consider just a normal part of life are actually accelerating our biological aging in ways that you don't even question anymore. In this episode, I'm joined with Dr. Kevin Mistry. He's a neuroradiologist, a longevity educator, and author of the book Primal Health Design. He spent decades looking at how modern lifestyles show up in the brain and the spine.
