Thermal water

Europe’s most abundant thermal source originates in the Tamina gorge near Bad Ragaz and was discovered long ago in the early Middle Ages (1242). The Tamina is the source of the healing thermal water, which flows at a delightful 36.5°C (body temperature). In the sixteenth century, the physician and alchemist Paracelsus praised the healing effects of the water, which due to its low mineral content and a temperature of 36.5°C is regarded as a warm spring.

In the early days, the first spa guests were lowered into the gorge on ropes. Since 1840, a pipe four kilometres in length has brought the water to Bad Ragaz. This laid the foundation for the area to gain a worldwide reputation as a bathing and spa resort, attracting notable guests such as Rainer Maria Rilke, Friedrich Wilhelm Nietzsche, Thomas Mann and Victor Hugo. Since 1872, Bad Ragaz has been recognised as one of the most prominent spa resorts in the world.


Tamina gorge – discovery and history

1242, hunters from the monastery Pfäfers discovered the 36.5°C spring. According to tradition, the monks of the nearby Benedictine monastery soon recognised the healing effects of the water. And so began the long history of Bad Pfäfers and later Bad Ragaz. In 1840, the warm thermal water was first routed in wooden pipelines from the Tamina gorge to Bad Ragaz. This pipeline had a length of 4,202 metres and a drop of 168 metres.

Therapeutic effects and spring analysis

Deep in the wild and romantic Tamina gorge beats the heart of the Grand Resort Bad Ragaz: the legendary spring from which thermal water has welled up at body temperature for many centuries. This water has inspired a unique combination of health and wellbeing.

Chemical properties of the thermal water

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 or hot spring (< 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.

Physical properties of the thermal water

Immersion in water in effect provides a transformed physical environment for the body. The physical properties of the water include the water pressure, buoyancy, water density and thermal conditions.

These bring about a whole host of positive effects pertaining to the heart, lungs, kidneys, circulation, motor system and even hormones. The most important effects on our body:

  • A reduction of vasoconstriction (narrowing of the blood vessels) in the legs (30%)
  • An increase in circulation (30%)
  • An improved use of the exchange surface of the lungs (pulmonary circulation and ventilation)
  • A reduction of blood pressure
  • An improvement of cardiac function (stroke volume and cardiac output increase by about 25%)

Time in the water reduces muscle tension and loosens connective tissue. Non-rheumatoid pain is alleviated and mobility in relation to the spine and extremities is improved.

Effects on the body

The warmth has positive effects on the locomotor system and our ability to relax. At this “comfort temperature“, the body neither has to produce heat nor release excess heat. Our body temperature therefore remains constant.

The water helps alleviate

  • Joint and spine conditions
  • Posture and movement disorders
  • Rehabilitation after operations of the locomotor system
  • Disorders of the vegetative-hormonal system
