Listening to music has direct effects on our body chemistry, it can lower the level of the stress hormone cortisol,while immunoglobulin A and killer cell counts increase, strengthening our immune system. These are some ofthe highlights found by researchers conducting a large-scale review of 400 research papers about theneurochemistry of music. While it is generally known that music has benefits for both mental and physicalhealth, it is interesting how direct the neurochemical mechanisms of listening impact our body, strengthening theimmune system and reducing levels of cortisol to decrease stress.

"We've found compelling evidence that musical interventions can playa health care role in settings ranging from operating rooms to familyclinics," says Professor Daniel J. Levitin of McGill University's

psychology department.

The research results gathered by Levitin and his postgraduate research fellow, Mona Lisa Chanda, shows thatmusic increased both immunoglobulin A, an antibody that plays a critical role in immunity of the mucoussystem, and natural killer cell counts (the cells that attack invading germs and bacteria).

The authors suggest a number of areas for future experiments in the field. "These include:

uncovering the connection between oxytocin, the so-called "love drug," group affiliation, and music,

administering the drug naltrexone-an opioid antagonist used during alcohol withdrawal-to uncoverwhether musical pleasure is promoted by the same chemical systems in the brain activated by other formsof pleasure such as food,

and experiments in which patients are randomly assigned to musical intervention or a rigorously matchedcontrol condition in post-operative or chronic pain trials. Suitable controls might include films, TV,comedy recordings, or audio books."
