Float History

Samana Float Center in Denver and Fort Collins

In 1953, John C. Lilly began a job studying neurophysiology with the US Public Health Service Commissioned Ocers Corps.

At the N.I.M.H. in 1954, with the desire of isolating a brain from external stimulation, he devised the first isolation tank, a dark soundproof tank of warm salt water in which subjects could float for long periods in sensory isolation. Lilly and a research colleague were the first to act as subjects of this research. What had been known as perceptual isolation or sensory deprivation was re-conceptualized as Restricted Environmental Stimulation Technique (R.E.S.T.). – Wikipedia

Many of the other terms related to floating are isolation tanks, chamber REST, relaxation therapy, relaxation technique and relaxation training.

Short-term sessions of sensory deprivation are described as relaxing and conducive to meditation. People use relaxation techniques for the following reasons, among others:
