Float tanks, also known as isolation tanks or sensory deprivation tanks, are popular tools for relaxation and meditation. But who invented them, and how have they evolved? Let's explore the history of float therapy and how it is used today.
The concept of the floatation tank was pioneered by John C. Lilly, a neuroscientist, psychoanalyst, and inventor who had a keen interest in the human psyche. Lilly was known for his unconventional methods and eccentricities, but he had a brilliant mind and an immense dedication to his unusual experiments.
While working at the National Institute of Mental Health in the early 1950s, John C. Lilly and his associate Jay Shurley developed the world's first float tank. The test subject would be suspended upright, wearing a blacked-out mask and breathing apparatus to restrict environmental stimulation. Lily continued working on his invention throughout the decade, later reporting his discoveries in a series of scientific papers on isolation tank research.
Still, it was not until the early 1970s that the float tank became the familiar design we recognise today. These advancements were made thanks to floating enthusiast Glen Perry, who was inspired by Lilly's writings to undertake a five-day workshop. During this workshop, he experienced sensory deprivation for himself and came out with newfound confidence, amazed he could speak publicly without fear for the first time.
However, Perry had difficulty floating in Lilly's original floatation tank design, so with the scientist himself, they began experimenting with using Epsom salt water to increase buoyancy. Perry's revised design laid the user horizontally instead of vertically. The user could float effortlessly and comfortably with the Epsom salts and water heaters, enabling greater relaxation. The design's success allowed Perry to start the first commercial sensory deprivation tank company with his wife, Lee. Through their company, Samadhi Tank Co., Glen and Lee Perry provided isolation tanks to the public – first through their facility in Beverly Hills in 1979, then all over the world through manufacturing for other floatation tank centres.
With the release of the film Altered States in 1980, floatation therapy experienced a boom across America. Its popularity waned in the late 1980s but revived again after a few years, though not at the level it was before.
However, floatation therapy is more popular than ever, thanks to the internet. In 2015, there were over 300 float centres in North America, up from the approximately 85 reported in 2011. Even more centres open every year, spreading the health benefits of the experience globally. Scientific research has continued to support the use of R.E.S.T (Restricted Environmental Stimulation Therapy) as a way to reduce stress and enhance overall well-being. Multiple papers have demonstrated positive effects in humans, from improving sleep quality to alleviating chronic pain.
Originating from Dr. John C. Lilly's early experiments at the National Institute of Mental Health and culminating in today's sophisticated float tanks found worldwide, float therapy has become an invaluable tool for relaxation and self-discovery.
