Floation frees the mind of outside stimuli and places a person in a highly relaxed and unencumbered state using a flotation tank - a specially designed chamber usually filled with about a foot of therapeutic, salt-saturated water. Once inside the tank, the person lies down and effectively negates the forces of gravity by floating effortlessly on the surface of the super-dense solution. Floating weightless in a sound- and light-proof environment can be unique and liberating experience contributing to stress reduction and enhancing concentration.
