The mud used at our hotels comes from the famous Hévíz thermal spring in Hungary, and from sediment collected by the hot springs of the river Vág in Piešťany in Slovakia. The therapeutic mud has a similar effect to that of the medicinal waters. The most characteristic feature of mud is its good heat storage and heat dissipation capacity. Warmth dilates the blood vessels and accelerates the metabolism. As a consequence, the treatment eases chronic inflammations. Warmth also relaxes the muscles and tendons and eases cramps. Of the mineral components of mud, iodine and bromine have a loosening effect, calcium, bromine and magnesium have a relaxing effect and sulphur boosts local metabolism. The temperature of the mud pack is usually 38-42°C, but the doctor can specify a lower temperature. The mud pack is applied on the body areas and joints prescribed by the doctor. The body is then wrapped into an insulating sheet. After 20 minutes, the mud is washed off, which at some hotels can be followed by a 15-minute dry body pack, but at least 15 minutes of rest is definitely recommended. The treatment eases the swelling of joints, muscular tension, and improves the nutrient supply of cartilages, connective tissue and spinal discs. Furthermore, it also strengthens the body’s anti-inflammatory and immune processes. The mud can also be applied partially (see: Partial mud pack). In Sovata, Romania, the mud is extracted from Bear Lake (Lacu Ursu) (see Balneotherapy: Salt bath) and is used in the same way. In addition to musculoskeletal disorders, the salty mud is also suitable for the treatment of certain skin disorders and gynecological diseases (see: Gynecological mud/peat therapy treatment).
