Unless you’re an astronaut, this is the only situation you will encounter where your body is free from the harmful forces of gravity. It’s like having a section of the Dead Sea just for you. This allows you to float effortlessly on the water, without fear of sinking or unwillingly rolling over. The buoyancy created by the dense epsom salt solution effectively removes the effects of gravity on the body, bringing you close to an experience of total weightlessness.

Using skin temperature 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.

Inside our floatation tank, we add up to 600kg of specially formulated epsom salt to water creating a 1000L solution, heated to 35.5 degrees – the temperature of skin. He devised the first float tank, a dark soundproof tank of warm salt water where subjects could float for long periods in sensory isolation. Neurophysicist Dr John C Lilly developed floatation therapy in the 1950s, when he was researching brain waves and altered states of consciousness through sensory deprivation.
