Episode Overview

In this episode, clinical neuropsychologist Dr. Justin Feinstein explores the science and therapeutic power of floatation therapy. Dr. Feinstein explains why the common label “sensory deprivation” is misleading and what actually happens inside a float tank. Rather than cutting off senses, floating creates a unique environment of deep rest, helping to calm the nervous system and promote mental recovery.

The conversation dives into Dr. Feinstein’s research on how floating is particularly effective for individuals suffering from PTSD, anxiety sensitivity, and even anorexia nervosa. His studies have shown that the more stressed someone is before entering the tank, the greater the positive impact floating has on their physiology and mental state. Dr. Feinstein also shares his vision of integrating float therapy into public health systems to support trauma survivors and those battling chronic stress and anxiety.

Dr. Feinstein discusses floating’s parallels with meditation, how it induces altered brainwave states, and its increasing use by elite athletes seeking improved recovery and focus.

Justin Feinstein, PhD Bio

Dr. Justin Feinstein is a clinical neuropsychologist and neuroscientist specializing in the treatment of anxiety and trauma-related disorders. He is internationally recognized for his pioneering research on floatation therapy and its effects on the nervous system, particularly in individuals with PTSD and high anxiety sensitivity. Dr. Feinstein’s work bridges the gap between cutting-edge neuroscience and practical mental health interventions, with a focus on natural, non-pharmacological approaches to healing.

As the founder and director of the Neuropsychology Research Program at LIBR (Laureate Institute for Brain Research), Dr. Feinstein led groundbreaking clinical studies exploring how floatation therapy can down-regulate stress responses and promote self-regulation in the brain. His research has contributed to a growing body of evidence supporting float therapy as a powerful tool for improving mental health outcomes, especially among those who have not responded to traditional treatments.

Beyond his research, Dr. Feinstein is a passionate advocate for integrating floatation therapy into public health systems to make it accessible to those most in need. He has consulted for clinics, athletic organizations, and wellness centers worldwide and is widely regarded as one of the leading voices on the therapeutic applications of floating.
