The concept of floating, or sensory deprivation therapy, originated in the 1950s with neuroscientist John C. Lilly. He was researching the effects of sensory deprivation on consciousness and brain activity at the National Institute of Mental Health.
Lilly developed the first isolation tank, which was a completely dark, soundproof tank filled with water. Over time, the water was infused with Epsom salt to allow for effortless floating, reducing sensory input and inducing deep relaxation.
By the 1970s and 1980s, commercial float centers started to emerge as people recognized the therapy’s benefits for stress relief, relaxation, and mental clarity. Since then, floating has gained popularity in wellness communities, professional sports, mental health treatments, and within our military for treatment of ptsd.
