The characteristics of Kızılcahamam thermal waters are suitable for a wide range of supportive treatment. The water temperature between 37 degrees Celsius and 47 degrees Celsius is used for bath cures, thermal pools and drinking treatments. Since natural methods are used to lower the temperature of the water, there is no loss of value. Kızılcahamam thermal water, whose temperature is naturally changed, provides more successful results in treatments with this feature. Kızılcahamam thermal waters are generally colorless and odorless. The fact that thermal water is sediment-free also makes it easy to use. Many different treatments can be easily applied with Kızılcahamam thermal waters, which have the feature of being less gaseous. Total mineralization of thermal water was measured as 2374,88- 2859,62 mg/lt. Thermal water contains fluoride, sodium bicarbonate and thermomineral. It is known that the pH value of Kızılcahamam thermal water, which has a pH value of 7.03, changes regionally. Expert advice must be taken into consideration in treatments applied by paying attention to this change. Having a conductivity of 2571 millival, the temperature of Kızılcahamam thermal waters may vary according to the source, just like the pH value.
