The reduced stimulation encountered in the floatation pod refocuses your attention to internal stimuli. At first this includes the novel sensations of floating effortlessly in darkness and quiet. The sensations of the body become more salient, making the flotation pod a walk-in biofeedback device.
This natural biofeedback initiates a self-regulation process that encourages relaxation. This relaxation is augmented by the full body absorption of magnesium that elicits the release of muscle tension.
As physical sensations become less noticeable, mental activity can come to the fore. For those not used to being alone with their thoughts this can be difficult. However, even unpleasant thoughts become more pleasant as the body descends into a more deeply relaxed state. Eventually even the parade of thoughts subsides and the mind enters a meditative state.
