Thermal waters are naturally heated water sources that emerge from the Earth's crust. They can be found in various locations, often associated with volcanic or tectonic activity. The temperature of these waters can range from warm to hot, sometimes exceeding 100 degrees Celsius. Thermal waters are rich in minerals, which can vary depending on the geological characteristics of the area. These waters are commonly used for therapeutic purposes in spas and wellness centers. Many people believe that bathing in thermal waters can provide health benefits, such as improved circulation and relief from muscle pain. Popular thermal water destinations include Iceland, Japan, and Italy.
