What we think can change our bodies. There is a quantifiable chemical link between mind and matter, spirit and body, imagination and reality. Neurochemicals cause us to be sexually aroused, determine the strength of our all-important immune system, cause us to have youthful vitality or feel old and sluggish, help our bodies repair themselves, and determine whether we fall in love. By altering or regulating the amounts of these brain chemicals, we can alter and regulate all those behaviors, processes, and mental states.
Neuroendocrinologist John Turner and colleague, Thomas Fine, showed that floatation lowers the levels of norepinephrine, epinephrine(also known as adrenaline), cortisol, and ACTH, among others. Elevated levels of these chemicals are directly linked to high levels of stress and stress-related illnesses. Tests on the effects of floatation on neurochemicals demonstrate both that floating does have a significant effect on the release of these natural substances, and that the effects have been uniformly beneficial. Scientists are now discovering that there is an intimate relationship between consciousness and brain chemistry; your attitudes and thoughts change, and can determine, your brain chemistry and your brain chemistry determines what happens in your body. All current evidence indicates that through effective use of the tank, floaters will be able to alter and influence the chemical secretions of the brain, and thereby affect every aspect of their behavior, including moods, emotions, immune response, and more. Psychologist Thomas Fine believes the most exciting possible use for floating is in developing the strength of the immune system.
