#474: Why PAIN Lingers After Healing: Nervous System Secrets, Neuroplasticity Hacks & The Future of Injury Rehab | With Garrett Salpeter
📍 Good news! My original Instagram is back! Please follow my original account at https://www.instagram.com/nathalieniddam/ and also my backup account at https://www.instagram.com/longevitywithnat/
Today, I’m joined by the innovative Garrett Salpeter, an engineer-turned-neuroscience trailblazer and the founder of NeuFit. In this episode, Garrett Salpeter reveals how a college hockey injury—and a near miss with surgery—catapulted him into the world of neurology and direct current stimulation. His personal story of healing, curiosity, and relentless pursuit of understanding the nervous system will change how you think about pain, movement, and recovery.
Together, we dig into why weakness and pain often persist long after tissues have healed, the hidden power of the nervous system as your body’s master regulator, and how stress, fear, and neuroplasticity shape your physical reality. Garrett Salpeter doesn’t just talk theory—he shares the real science behind direct current therapy, the role of electrical fields in healing, and why your brain sometimes holds you back even when your body is ready to move forward.
If you’re curious about cutting-edge rehab, how to break free from chronic pain, or how harnessing your nervous system can supercharge your healthspan, this episode will open your eyes to new possibilities for healing and human performance.
