158. Dr. Kavin Mistry: Primal Health Design, Biological Aging, and Reconnecting with Human Biology — Extend Podcast with Darshan Shah, MD

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.
