One of the causes, that has led Bad Neuenahr to develop as a health resort is 'alkaline thermal' spring. Three 'alkaline thermal' springs are found in this health resort. Apart from Bad Neuenahr, there are very few places where these springs are available. The water of these springs contain large quantities of carbon. This water is suitable for bathing as well as drinking. The water is acidic as well. It contains a high level of hydrogen carbonate, magnesium and sodium. The carbonic acid content is also found in this form of water. This natural water maintains a general temperature between 34 degrees and 41 degrees Celsius.
Few of the diseases, that are healed by this natural spring waters of Bad Neuenahr include rheumatic diseases, cardiovascular disease, metabolic disorders, muscular-skeletal illnesses. The mud therapy is also offered by a few therapeutic centers in Bad Neuenahr.
