Thermal water

General information concerning the thermal springs at Loèche-les-Bains

The thermal springs at Loèche-les-Bains have been used without interruption from Roman times to the present day. The water of Loèche-les-Bains takes more than 40 years to course through underground passages and around 65 thermal springs in all are mentioned in the land register. They mark the emergence of warm or hot percolated water at temperatures of up to 51°C. The total capacity at Loèche-les-Bains has been conservatively estimated at approximately 3,000 litres/minute of pure thermal water.


Composition of the thermal water

All thermal water at Loèche-les-Bains comes from the same thermal aquifer. The water is rich in calcium sulphate and contains slightly above-average levels of sodium, strontium and iron, and a significant quantity of fluorine. It has a high content of dilute solids (1,800-2,000 mg/litre). These unique properties give the water used in swimming pools at the Leukerbad Clinic its therapeutic qualities.

The mineral springs at Loèche-les-Bains contain mainly calcium sulphate, i.e. gypsum. Hot water containing gypsum soothes rheumatological and neurological disorders and aids recovery after accidents.


Effects of heat

The action of heat relaxes the muscles, improves the elasticity of connective tissue and liquefies synovial fluid – which has a positive effect on painful arthritic joints.


Chemical and mechanical effects

  • As the skin absorbs and repels water, an exchange of ions is created.
  • Thanks to the water’s buoyancy, the effective weight of an immersed body is less than 10% of its normal level. Movements are therefore easier to make in water and exert less stress on joints. In addition, in water, support muscles relax automatically in a reflex action.
  • Viscosity and resistance to friction create an obstacle to the body’s movements. As a result, during training therapies in water (swimming with flippers, WetVest, Aquajogging), muscles are strengthened and movements harmonised.



  • During the onset of rheumatological crises, in the presence of acute lumbar or back pain
  • In cases of severe high blood pressure or any type of decompensated heart disease
  • Counter-indication is absolute for immunodeficient patients after corticotherapy or treatment with immunosuppressives, as well as kidney transplant and dialysis patients
