Artificial versus Natural Hot Springs

The difference between natural and artificial hot springs include: 

A Natural pH Value

The typical pH value of tap water is 7, but natural hot springs have higher and lower pH values. Those with higher pH values exceed 8.5 and have a purifying and detoxicating impact on the skin. Those with lower pH values are under three and have a disinfecting effect on the skin. 

Higher Levels of Salt Content

Some thermal waters contain brine, a combination of salt and water. This combination cannot occur in tap water. Therefore natural springs have more buoyancy than artificial ones. 

Unique Experience

Taking a bath in nature has an exceptional experience. The warmth of the Earth and the aerosols that drop when the water evaporates enhance the feeling. There are also no chemicals in the water to stabilize the pH value.
