Food for thought

Here is some food for thought.
A recent research study  completed by Levitin and colleagues published in the journal Trends in Cognitive Sciences, suggest that listening to music has physiological benefits. Researchers studied patients who were about to undergo surgery. Randomly assigned participants listened to either music or took an anti-anxiety drug. Scientists tracked patient's ratings of their own anxiety, as well as the levels of the stress hormone cortisol.
The results showed that patients who listened to music had less anxiety and lower cortisol than people who took drugs. Levitin cautioned that this is only one study, and more research needs to be done to confirm the results, but it points toward a powerful medicinal use for music.
"The promise here is that music is arguably less expensive than drugs, and it's easier on the body and it doesn't have side effects," Levitin said.
