Flotarium - Floating clinic in Barcelona and Terrassa. Floatation tanks are light-proof, sound-insulated capsules which contains a shallow 30 cm pool containing about water saturated with an Epsom Salts solution - five times denser and more buoyant than sea water. You float effortlessly on the surface with all parts of your body firmly supported. Your muscles no longer have to fight against the constant downward push of gravity, the single greatest cause of wear and tear to bones, joints and body tissue. As muscle tension melts away, you find yourself floating weightless and free, like an astronaut in zero gravity conditions. This is an amazing experience and triggers a deep state of mental and physical relaxation.
