Salt Therapy is totally safe. It is a 100% drug free, non-invasive and a very comfortable treatment. Those that should avoid salt rooms are people that suffer from severe chronic respiratory issues and those with open wounds and sores. Due to the low controlled concentration of salt (15-20mg/m³) dry salt therapy is usually side-effect-free. We do suggest that anyone going into the salt room should remove all jewelry and electronic devises because any salt can be corrosive to exposed metal.
