Inside the floatation tank is 500kg of specially formulated salts added to 1000 litres of water, creating a 30 cm deep solution, which is heated to 35.5 degrees C (skin temperature). The temperature of the water means that once you are settled in the tank, it is virtually impossible to distinguish between parts of the body that are in contact with the water, and those that aren’t.
The buoyancy created by the dense Epsom-salt solution effectively removes the effects of gravity on the body, and brings the individual close to an experience of total weightlessness. Aside from outer space, this is the only environment you will encounter where your body is free from the harmful forces of gravity. With ear plugs in and, if you wish, the tank’s interior lights off, the quiet darkness allows the mind to drift into the deepest state of relaxation possible.
A huge amount of brain power is used every second in order to deal with the strain that gravity places on one’s body. Floating removes this stress, and perfectly supports your body in a cushion of silky skin-temperature liquid. Freed from all sensation of gravity, temperature, touch, sight and sound (which together account for 90% of normal neuromuscular activity), you conserve and redirect vast amounts of natural physical and mental energy.
The ultra-deep relaxation provided by floating “resets” the body’s hormonal and metabolic balance, strengthening resistance to and accelerating recovery from the effects of stress, illness, injury or strenuous exercise. With no commands needing to be sent out, the logical side of the brain is rendered redundant, and it's activity slows down until it synchronizes with the creative side. This leaves the individual in a dream-like state, akin to the thoughts experienced just before you go to sleep. In this state, the brain releases vast amounts of endorphins.
While the state of relaxation may be deep and profound, the individual’s brain stays dreamily alert. The brain gradually shifts from its usual waking beta state to generate deep alpha, theta or even delta waves, the state-of-mind that advanced meditators may reach through hours of meditation and years of training. You can achieve this in a matter of minutes just by lying back into the silky warm sea of bliss that is the floatation experience!
