The impact of a single sauna session on the electrodermal activity (EDA) as evaluated with the Ryodoraku method

Journal Title: Complementary & Alternative Medicine in Science - Year 2013, Vol 1, Issue 2

Abstract

Background. The problem of measurements of electrodermal activity (EDA) with the use of the Ryodoraku method, after application of Finnish sauna, has not been previously discussed in scientific reports. Material and methods. The study involved 46 healthy men aged 21–24 years. The experimental measurement of EDA was made before and after a Finnish sauna session. In order to check normality of the distribution of the obtained results the Kolmogorov–Smirnov test (K–S test) and the Lilliefors test were used. In order to assess the statistical significance of differences between the mean values of the first and second measurement, the parametric Student's t-te st was applied for dependent samples. The level of significance was set at p < 0.05. Results. Significant differences between the measurements before and after the sauna session, except for the lung meridian and the liver m eridian, were noted. The differences between the measurements, observed in the experiment, did not show a unidirectional trend for all measured points. T he mean values of the following meridians: heart, small intestine, triple burner, large intestine, kidney, gallbladder, and stomach, showed a statistically significant increase in the second measurement. A significant decrease in the measured values was recorded in the case of the pericardium, spleen-pancreas, and urinary bladder meridians. Conclusions. Analysis of the results of EDA measurements taken in this study indicates a complex nature of the response of the autonomic nervous system related to a sauna session.
