Thermal treatments can be defined as “natural” more than any other therapy. In fact, they are based on (mineral) thermal water and mud that derives from the maturation process of soil or clay, bringing the development of algae and microorganisms that have a curative effect on our body. Furthermore, thermal treatments, such as mud and bath therapy, hydrokinesitherapy and inhalations are constantly studied according to the criteria of traditional science while their efficiency is demonstrated by several research studies, comparable to pharmaceutical drug studies before going on the market. That is why thermal means natural and, above all, efficiency.
