Is an i-sopod tank just a floatation tank or is it also a sensory deprivation tank?
The i-sopod is a floatation tank and a sensory deprivation tank – floatation tanks and sensory deprivation tanks are the same thing. They all use supersaturated Epsom saltwater at skin temperature to achieve null gravity. Floatation tank is just the new name for it because sensory deprivation has negative associations for most people. However, not all floatation tanks are the same and not all floatation centers are the same. To get the best benefits, you want to float in a very quiet place because it’s impossible to completely soundproof a floatation tank. I floated once in a poorly insulated (cold) floatation tank in a noisy floatation center and got no benefits, but most of my experiences are extremely relaxing (warm water, warm air, no noises) and very beneficial. The i-sopod is the newest design, but it accomplishes the same thing as the floatation tanks from the 1970s.
