General Information

Hévíz Thermal Lake

Hévíz Thermal Lake is the largest biologically active, natural thermal lake in the world. The bottom of the several thousand years old thermal lake is covered in peat and the lake is supplied by springs located at a depth of 38 meters providing the lake with hot and cold water rich in minerals. Due to the 410 litre water flow the lake is believed to be completely replenished in every three days. The upwelling water temperature is at 38.5ºC at the spring. The temperature of the water during summer is about 37ºC, during winter it does not drop below 24ºC offering a suitable bathing location even during the very cold months of the year.

Composition of the thermal water and medicinal mud:

Hévíz Thermal Lake contains dissolved and gaseous ingredients in equal proportion, combining the beneficial characteristics of carbonic, sulphuric waters, medicinal waters rich in calcium, magnesium, hydrogen carbonate, and slightly radioactive medicinal waters. The radioactive medicinal mud layer, which covers the lake bed is of special interest. This unique Hévíz medicinal mud contains organic and non-organic materials, furthermore radium salts and reduced sulphides and healing factors built up by organic acids represent a one of a kind value. The more than ten thousand years old, sulphuric thermal water and medicinal mud containing slightly radon emanations applied together with complex physiotherapeutic treatment is very proven to be very effective for rheumatic and locomotor disorders.

Why is the Hévíz medical treatment unique?

Hévíz medicinal treatment is unique due to the components and effects of the thermal lake. Three eras of geohistory meet here at the lake and they jointly offer everything, which can be utilised by medical science. Dolomite provide the anti-inflammatory calcium and sedative magnesium, limestone provides the vasodilator carbonic acid, carbonate softens the skin, effective inert gases (in a quantity, which is harmless to our health) boost the adrenal gland to produce multiple anti-inflammatory hormones, stimulate the thyroid gland to produce several bone-developing hormones, this way in the case of joint diseases and osteoporosis patients are able to improve their condition by using their own natural hormones. The indifferent temperature of the lake does not trouble the heart and blood circulation. If patients take up a vertical position during bathing, mobility and blood circulation is significantly improved and painful muscles cramps can also be alleviated.
