The Seven Theories of Floating
by Michael Hutchinson, author of The Book of Floating

There’s no doubt that floating works – as a therapeutic, educational and entertainment tool it has powerful effects on a number of levels, including the physical, emotional, intellectual and spiritual. But why is the floatation environment so effective? What can be so actively beneficial in an essentially passive device? This is a question that has intrigued scientists, and today there is floatation research going on in laboratories around the world. The evidence accumulated so far falls into a number of distinct, though interrelated explanations. Among the most important are as follows:

1 THE ANTIGRAVITY EXPLANATION
2 THE BRAIN WAVE EXPLANATION
3 THE LEFT-BRAIN RIGHT-BRAIN EXPLANATION
4 THE THREE BRAIN EXPLANATION
5 THE NEUROCHEMICAL EXPLANATION
6 THE BIOFEEDBACK EXPLANATION
7 THE HOMEOSTASIS EXPLANATION

7. The Homeostasis Explanation

The human body has an exquisitely sensitive self-monitoring and self-regulating system that is constantly working to maintain the body in homeostasis – an optimal state of balance, harmony, equilibrium and stability. Considered in these terms, we can define stress as a disruption of our internal equilibrium, a disturbance of our natural homeostasis. Research now indicates that many of floating’s most powerful effects come from its tendency to return the body to a state of homeostasis. When we view the mind and body as a single system, it becomes clear that external stimuli are constantly militating against the system’s equilibrium, every noise, every degree of temperature above or below the body’s optimal level, every encounter with other people, everything we see and feel can disrupt our homeostasis. But when we enter the tank, we abruptly stop making constant adjustments to outer stimuli. Since there are no external threats, no pressures to adapt to outside events, the system can devote all its energies to restoring itself. The normal state, of course, is health, vigour, enthusiasm, and immense pleasure in being alive.
