BACKGROUND:

Spa reaction is an adaptive response of an organism, emerging as a result of external factors. It is a positive element of spa therapy leading to metabolic changes, which are important for the body. The effect of these changes is an increase in immune activity and regenerative reactions of the body. The mechanism of the response is not fully known.

OBJECTIVES:

The aim of the study was to evaluate the changes observed in the field of the integrated antioxidant system of the body in the course of radon therapy, especially in reference to spa reaction.

MATERIAL AND METHODS:

The study was conducted in the health resort in Świeradów-Zdrój. The observation regarded patients undergoing treatment with radon water. Before the treatment, after 5 and 18 days of treatment, the total antioxidant status (TAS) was evaluated with the use of a standard colorimetric assay. The study group consisted of 35 patients with degenerative joints and disc disease. The control group consisted of 15 people selected from the employees of the spa, also suffering from osteoarthritis, who did not undergo radon therapy (without contact with radon).

RESULTS:

On the 5th day of the treatment, in both groups, the TAS increase was observed with significantly worse results in the control group. After the treatment, in the study group, there was observed an increase in TAS, whereas in the control group, a significant decrease in the TAS concentration was noted.

CONCLUSIONS:

A beneficial effect of radon treatments on the growth of TAS in the body of the patients treated in the spa was demonstrated. The increase in the TAS concentration on the 5th day of treatment may indicate the relationship between these changes and the phenomenon of spa response. The changes are a result of low doses of ionizing radiation originating from radon dissolved in medicinal water, used in the course of the therapy.
