#100: Float Therapy: Science, Healing & Peak Performance - Justin Feinstein, PhD

In this episode, neuroscientist and clinical researcher Dr. Justin Feinstein discusses the fascinating science and therapeutic potential of flotation therapy. Often misunderstood and mislabeled as “sensory deprivation,” Dr. Feinstein explains why this is a misnomer and what’s truly happening inside the float tank. Instead of depriving the senses, floating creates an environment of deep physical and mental rest, allowing the nervous system to reset. We explore Dr. Feinstein’s pioneering research on using float therapy to help individuals with PTSD and high anxiety sensitivity. He also shares insights into how flotation therapy could become a valuable tool in the public health system, especially for trauma survivors and people with severe anxiety. Dr. Feinstein highlights compelling case studies, including patients with anorexia nervosa who experienced meaningful relief through floating, as well as its growing popularity among high-performing athletes looking to optimize recovery and mental performance. Whether you’re new to flotation therapy or familiar with the practice, this conversation reveals its untapped potential and emerging role in both mental health and peak performance.
