The science of Floatation Therapy


What is a floatation tank and how does it work?

 The float tank is like a large Jacuzzi (about the size of a queen size bed). Inside is about 30 cm of heated mineral water. The water is heated to your external skin temperature – about 34.5 degrees C. Because of the density of the salt solution, when you lie back in the water, your body pops to the surface like a cork – completely supported by the water (like in the dead sea). Every muscle in your body is completely supported by the water, and you no longer having to deal with gravity. You float weightless like an astronaut in space. 

With the temperature of the water exactly the same as your skin temperature, you begin to lose the sense of where your body ends and the water begins.

 The tank is completely dark inside, and totally, serenely silent.  Effectively removing all environmental  stimulation from your body has powerful effects on both the body and mind, the most noticeable of which is a deep physical and mental relaxation and a feeling of euphoria. 

“After floating we seem to perceive the world with startling directness, richness and clarity when we get out of the float tank the one thing that we know immediately is that it is worth doing simply because it feels so good.”

(Michael Hutchison The Book of floating) 


When we shut out or restrict environmental stimuli, we become more aware of those things that are still available to us. In this case when we shut out light, sound, tactile sensations, gravity, other people and movement, what is left is our Self: the physical reality or our skeletal muscles, out thought, emotions, intuitions, mental images. Our awareness of these realities is of a subtlety and intensity simply not possible when our senses are directed outward, responding to external events. 


There is overwhelming scientific evidence that by becoming more acutely cognizant of our inner processes, we can actually exercise conscious control of them e.g. simply focusing awareness in a certain way, we can lower blood pressure, strengthen our immune system, slow heartbeat, release or inhibit the release of hormones, alleviate pain, and alter the activity of heart, muscles, brain and mind. 

Other benefits from floating are: Immediate reduction of stress; Decreased levels of depression, increased creativity and productivity, decreased physical pain, helps with insomnia, speeds up recovery from sport, injuries and illness, alleviates tension headaches, the tank is an excellent tool for decreasing or removing addictions,  weight loss, self healing, and for improving the results of visualisation, meditation, self hypnosis and other self management and personal growth techniques.
