 This is Scientific American 60 second Science, I am Sophie Bushwick, Got a minute~

 
Opera and classical music can relax you – and maybe your immune system, if results with mice extend to us. Because mice that got heart transplants and who listened to opera and classical music had better outcomes than those exposed to other sounds. The work is in the Journal of Cardiothoracic Surgery. 
 
A mismatched organ transplant typically gets rejected. After receiving mismatched heart transplants, mice spent a week hearing silence, a single-frequency tone, or one of three types of music: Verdi's La Traviata, Mozart, or the New Age artist Enya.
 
The strong immune response in the control mice and those who listened to single frequencies caused rejection1 after a week, and the Enya group lasted only a few days more. But the hearts in the Mozart group beat for 20 days and the Traviata group survived 26 days.
 
Perhaps classical music calms the immune system, decreasing its responsiveness – the Traviata mice had fewer white blood cells and immune-signaling molecules2. Or maybe mice just prefer Verdi to Enya.
 
Thanks for the minute for Scientific American, I am Sophie Bushwick.
