What Does Hévíz Treat?

hévíz is the leading European centre for musculoskeletal treatment in a natural lake environment — a combination of balneology and nature therapy that no tiled-bath spa can replicate.

– arthrosis — continuous movement in warm water preserves joint function (★★★) – Rheumatoid arthritis — sulfur water reduces inflammatory flares – Bechterew’s disease — underwater traction and warmth improve spinal mobility – Chronic back pain — underwater traction decompresses the spine – Herniated disc — underwater traction in complete muscular relaxation – Post-joint replacement — water-based rehabilitation without joint load – osteoporosis — movement in water with minimal fall risk – Gout — sulfur promotes uric acid excretion – Psoriasis — sulfur water and sunlight calm the skin

Treatments in Hévíz

Lake bathing: The defining experience. Unlike a 20-minute thermal bath, you can stay in the lake for 30–40 minutes — the massive water volume and constant flow prevent overheating. You move slowly, half-swimming or hanging from a bar, while the warm water does the therapeutic work. The buoyancy reduces body weight by 90 percent — joints are completely unloaded. The sulfur is absorbed transdermally, reaching joint capsules within minutes. In winter, a heated covered walkway leads from the bathhouse directly into the steaming lake — bathing in 38 °C water at 0 °C air temperature, snow falling around you, water lilies drifting past, is an unforgettable spa experience.

Underwater traction: Invented in Hévíz in 1953. The patient is suspended vertically in 38 °C thermal water and gently stretched by body weight. The heat eliminates all muscle guarding — the intervertebral discs decompress without painful counter-reflexes. This is the most effective non-surgical treatment for herniated disc and chronic back pain in European balneology, and Hévíz remains the reference centre for the technique. Three sessions per week, 20 minutes each. Physiotherapy treatment — learn more.

Mud pack: The sulfur-rich sediment from the lake floor is matured for months with thermal water and applied as a full-body or partial pack at 40–42 °C. The organic compounds — humic acids, enzymes, and sulfur derivatives — penetrate deep into joint tissue. The packs are particularly effective for arthrosis and rheumatism, complementing the lake bathing.

Drinking cure: The Hévíz thermal water is prescribed as a drinking cure for digestive disorders and gout. The sulfur compounds support liver detoxification, and the mild mineralisation makes the water gentler on the stomach than highly mineralised drinking cures.

History and Atmosphere

The healing properties of the Hévíz lake were known to the Romans — coins found on the lake floor date to the 2nd century AD. The first bathhouse was built in the 18th century, and systematic spa operation began around 1900 when the Festetics family, Hungarian aristocrats who owned the surrounding estate, developed the infrastructure.

The lake itself is a volcanic phenomenon: the 38 °C thermal water rises from a spring at the lake bottom with a flow rate of 410 litres per second. Colder springs at the lake edges at 17 °C create a temperature stratification that sustains the unique ecosystem. The tropical red water lilies were introduced from India in 1898 and have thrived ever since in the constantly warm water — a botanical anomaly in the middle of Europe. In winter, the lake surface steams, and the lilies continue to bloom under the vapour — an otherworldly sight.

The underwater traction technique was developed by Hungarian physicians in 1953 and placed Hévíz on the world map of medical balneology. It remains the resort’s signature contribution to orthopaedic medicine.

Hévíz today is a flourishing spa town with ten hotels around the lake. The atmosphere is unique: mornings spent floating among water lilies in steaming thermal water, afternoons on the sun terrace overlooking the lake. For guests who want a natural spa experience — not a tiled pool, not a clinical facility, but a living lake — Hévíz has no equal in Europe.
