The history of Floatation-REST (Reduced Environmental Stimulation Therapy) dates back to the 1950’s when Drs. Jay Shurley and John Lilly at the National Institute of Mental Health became interested in understanding how the human brain would respond to an environment devoid of external sensory input. The float environment systematically minimizes external sensory input to the nervous system including signals from visual, auditory, olfactory, gustatory, thermal, tactile, vestibular, gravitational and proprioceptive channels. Since its discovery, there have been a number of publications exploring the potential therapeutic benefits of floating. The most consistent observation to date has been significant reductions in levels of subjective stress and increases in relaxation as measured from pre- to post-float. Concomitant with these subjective findings, floating has also been reported to decrease blood pressure, heart rate, and cortisol levels. A meta-analysis published in 2005 found a large overall effect size for stress reduction, with most past float studies focused on healthy populations.
Clinical research investigating Floatation-REST, although limited, has reported largely beneficial effects across a range of different stress- and pain-related conditions, including: hypertension, chronic tension headaches, chronic muscle tension pain in the back and neck, and stress-related pain with burnout depression. There have also been several studies focused on individuals with clinical anxiety, including generalized anxiety disorder, posttraumatic stress disorder (PTSD), anorexia nervosa, panic disorder, agoraphobia, and social anxiety disorder, with many of these patients also presenting with comorbid major depressive disorder. The evidence published thus far suggests that Floatation-REST is a safe technique for rapidly reducing levels of stress, pain, and anxiety. Clinical trials are currently underway in America, Germany, and Sweden investigating the long-term impact of floating in patients with anxiety disorders, anorexia nervosa, chronic pain, fibromyalgia, and insomnia. As the evidence base continues to grow, we will continue to update this repository of peer-reviewed publications studying the clinical effects of Floatation-REST.
