Opera and classical music may help to reduce the rejection of newly transplanted organs by influencing the immune system.
Scientists have already found that listening to music can reduce anxiety after heart attack and reduce pain and nausea during bone marrow transplantation.
The evidence point to an influence on the parasympathetic nervous system which regulates the kind of bodily functions we have no conscious control over like digestion.
Now researchers from Japan working with mice have found that opera and classical music both influenced the rejection rate in organ transplant.
They found, however, that opera and classical music worked best. Single frequency monotones and new age music had no impact.
Their findings have been published in the Biomed Central Journal of Cardiothoracic Surgery.
