Flotation Tanks

Another method for inducing profound relaxation involves the use of sensory deprivation. This is based on the discovery of the Ganzfeld effect, whereby individuals exposed to an unvarying visual field (such as in a white-out produced by a blizzard) enter an altered state of consciousness and begin to experience a wealth of internally stimulated visual imagery. The most effective application of the Ganzfeld effect involves the use of flotation tanks (Hutchinson, 1984).

The Float Experience

A float tank is an enclosed container roughly the size of a large bathtub with a lid. Inside is ten inches of warm water, heated to a constant temperature of 93.5°F (equal to the temperature on the surface of your skin) and inundated with Epsom salts to enable you to float effortlessly. When you shut the door you are enclosed in total darkness. All sounds are blocked out by earplugs. But this sensory deprivation chamber goes beyond a simple Ganzfeld situation by restricting other sensory input as well. Tactile sensations are eliminated by lying back and floating in a pool of water at body temperature, causing you to lose your sense of separation from the liquid. The boundaries of your body seem to disappear, thus eliminating sensations of touch, pressure, or friction. The effects of gravity are also nullified by the fact that your body is totally suspended in fluid. The result is that you are almost completely deprived of external sensory stimulation. Scientists estimate that at least 90 percent of our brain's activities are involved in processing the wealth of external stimuli that bombard us at any given moment. When we are freed of the need to monitor external stimuli, our mind opens up to internal, often unconscious mental processes that are ordinarily obscured. One of these processes is internal imagery.
