A number of studies have reported physiological effects of music. Different types of music have been found to induce different alterations. Although some physiological and psychological parameters have been demonstrated to be influenced by music, the effect of music on hemorheological parameters such as red blood cell (RBC) deformability and aggregation are unknown. This study aimed at investigating the effects of classical and rock music on hemorheological parameters in rats.
Material and Method: Twenty-eight rats were divided into four groups: the control, noise-applied, and the classical music- and rock music-applied groups. Taped classical or rock music were played repeatedly for 1 hour a day for 2 weeks and 95-dB machine sound was applied to the noise-applied rats during the same period. RBC deformability and aggregation were measured using an ektacytometer.
Results: RBC deformability was found to be increased in the classical music group. Exposure to both classical and rock music resulted in a decrement in erythrocyte aggregation, but the decline in RBC aggregation was of a higher degree of significance in the classical music group. Exposure to noise did not have any effect on the parameters studied.
Conclusions: The results of this study indicate that the alterations in hemorheological parameters were more pronounced in the classical music group compared with the rock music group.
