4 results about "Isolation tank" patented technology

An isolation tank, often referred to as a sensory deprivation tank (also known as float tank, float pod, float cabin, flotation tank, or sensory attenuation tank) is a pitch-black, light-proof, soundproof environment heated to the same temperature as the skin. The tank is filled with 10 inches of water which contains enough dissolved Epsom salt to create a specific gravity of approximately 1.275. This environment allows an individual to float effortlessly on the surface of the water. The primary function of the isolation tank is to eliminate as many of the external senses as possible. They were first used in 1954 to test the effects of sensory deprivation. Flotation tanks are widely advertised as a form of alternative medicine, but beneficial health effects are unproven.
