Stress produces a chain reaction in the body releasing stress chemicals adrenaline, cortisol, ACTH, and lactate which are known to weaken the body's immune system and create feelings of depression.
While floating, the chemistry of the body changes. Stress hormones are removed from the bloodstream and replaced with beneficial endorphins. The "Pleasure" chemicals released create feelings of confidence and well-being. These changes occur naturally and spontaneously as by-products of deep sensory relaxation. No training or techniques are required. Just lie back and let it happen.
