Thermal water
Naturally warm spring water — warmth and minerals that loosen the muscles and take the strain off the joints.
01What is thermal water?
Thermal water is natural spring water that rises from deeper layers of the earth and is at least around 20 °C at the source — often considerably warmer in Romania. On its way up it picks up minerals and gases, which is why it is frequently rich in minerals or sulphur. It is precisely this combination of natural warmth and dissolved active substances that has made it the heart of balneotherapy for centuries.
The composition varies greatly depending on its origin. The overview below shows the three most common types of water and their traditional benefits.
| Water type | Brief benefit |
|---|---|
| Oligometallic | Mild, low in minerals — gentle on the joints and suitable for long baths |
| Sulphurous | Traditionally valued for rheumatism and skin complaints |
| Saline (chloride) | Greater buoyancy, relieves the joints and supports movement therapy |
These details are for guidance only. The exact composition varies by spring and facility.
02Effect & application

- Circulation — The warmth widens the blood vessels and promotes circulation.
- Muscles — Tense muscles relax in the warm water.
- Joint pain — Warmth eases pain and improves mobility.
