Based on its composition, the local Bad Ragaz spa water belongs to the main group of chloride-hydrogen carbonate-sulphate waters. In addition to these principal components, it also contains trace elements such as iron, fluoride and iodide ions, as well as sulphide-sulphur. The spring is classified as an acratotherm (< 1000 mg/l mineral content, temperature > 20°C) and has proved its worth in treating complaints of the locomotor system and diseases of the musculoskeletal system.

Immersion in water represents a change of physical environment for the body. Among the physical properties of water are water pressure, buoyancy, water density and thermal conditions . These bring about diverse responses in the body involving the heart, lungs, circulation, kidneys, motor functions, blood and hormones. The most important effects include: reduced wall tension of the resistance vessels in the legs (30%), improved blood flow (30%), better distribution of the pulmonary exchange area (pulmonary blood flow and ventilation), reduction in arterial blood pressure, increased heart function (stroke volume and cardiac output increase by 25%). Spending time in water relaxes the musculature and connective tissue. It alleviates non-inflammatory pain and improves mobility in the spinal column and extremities.

The warmth has a beneficial effect on the musculoskeletal system and the ability to relax. At this comfort temperature, the body does not need to produce heat nor to give off excess heat. The body temperature thus remains constant.
