Over half a tonne of Epsom Salts in each float room has a profound relaxing effect on the muscles, easing away any tightness or stiffness in your body. The Magnesium in the Epsom Salts also calms the nervous system. A fantastic antidote to the fact that the nervous system takes longer to relax and shut off than the rest of the body, bringing a serene calmness that would be otherwise out of reach.
