Although the benefits of float tanks only recently garnered lots of buzz, they’ve actually been around since the 1950s and used in Europe on-and-off since the 70s.

Some report that float tanks can actually bring about a “psychedelic experience.” Over the last few decades, esoteric communities promote floating as a way to promote “spiritual awakeness,” emotional breakthroughs and enhanced clarity of mind. While these benefits are difficult to prove, recent research published in the Journal of Complimentary & Behavioral Medicine now suggests that sensory deprivation may actually work by reducing the body’s stress response, inducing deep relaxation and quieting mental chatter.
