Magnesium SulphateWhy do we use it?
The water in the float environment is saturated with over 500kg of Magnesium Sulphate, otherwise known as Epsom Salt. It is the high density of this Epsom Salt solution which gives the buoyancy and feeling of weightlessness which is at the heart of the floatation experience.
In the early days of the history of floatation Sodium Chloride was used, but was found to be too irritant to the skin. Epsom Salt on the other hand feels silky and luxurious on the skin, which can be one of the pleasures of floating.
Bathing in Epsom Salts has a long history and many people believe it has beneficial effects. The informal name ‘Epsom Salts’ originates from its discovery in Epsom in 1618. It is claimed to have wide-ranging benefits from soothing aching muscles to aiding the healing of scar tissue.
Many people take Magnesium as supplements or creams, for its health benefits. Research has shown that Magnesium can be absorbed through the skin via creams. There is a helpful summary on the University of Hertfordshire website.
Current research is ongoing at LIBR, to establish to what extent magnesium is absorbed while you are in the float environment.
