Radon Katharinenquelle (Catherine spring) in the Sibyllenbad
Long-lasting pain relief in case of rheumatic and spinal diseases – this is the main indication of the rare radon spa water. The radon Katherinenquelle (Catherine spring) of the Sibyllenbad in the Upper Palatinate Forest was already tapped in 1964. The radon therapy as a series of individual tub sessions has been practiced in Neualbenreuth since 1989 – then in the bathhouse Maiersreuth – and since 1996 with an increased tub capacity in the Kurmittelhaus Sibyllenbad in the Kurallee.
Radon is a highly volatile noble gas dissolved in the spa water. As a slightly radioactive element it disintegrates with a half-life period of 3.8 days. In the tubs of the Sibyllenbad, an optimum radon concentration between 1.600 and 2.000 becquerel for pain therapy is ensured.
In the frame of a Sibyllenbad radon therapy, a series of at least six to twelve single baths is prescribed. The duration per bath at 36° C is 20 minutes with a subsequent resting period of another 20 minutes.
During the bath, the patient absorbs the radon via skin and lungs and releases it again through the lungs. In the course of such radon transfer, a small part of the element disintegrates into its progenies within the body. The released alpha radiation is responsible for processes on the cell level alleviating pain, reducing inflammations and positively influencing the immune system as well as the endogenous repair mechanism. For the guest, a radiation dose of max. 2 mSv (with approx. 10 baths) is harmless. The harmlessness is also true for the staff in the tub area.
Unique radon – carbon dioxide combination baths
The radon – carbon dioxide combination baths are unique in the Sibyllenbad. The therapy is based on the prior emission of carbon dioxide spa water and the subsequent addition of radon spa water under the water surface. The radon – carbon dioxide combination bath comprises approx. three tub fillings of spa water. The previous bathing in carbon dioxide mineral spa water improves the blood flow, relieves the cardiovascular system and at the same time improves the absorption capacity through the skin. Thus, the effectiveness of the radon therapy is significantly improved.
The radon – carbon dioxide combination baths in the Sibyllenbad were essentially developed by Prof. Dr. Dr. Wolfgang A. Grunewald who acted as medical director and balneologist in the Sibyllenbad from 1989 to 2012. Through the innovation of radon – carbon dioxide combination baths, the radon therapy for rheumatism patients with cardiovascular diseases as well as hypertension (high blood pressure) was made possible. The combination therapy is especially gentle and well tolerated.
The large regeneration bath – radon, carbon dioxide and oxygen
In the large regeneration bath, the patient inhales medical oxygen during the radon – carbon dioxide combination bath. The oxygen supply in the organs is thus improved. The large regeneration bath with radon, carbon dioxide and the oxygen inhalation is above all suited for the maintenance and ensurance of life quality in old age, age prevention and also for gerontological prophylaxis.
Radon baths in the Sibyllenbad are subject to a medical prescription.
