Exercising with machines also seems to raise a person's pain threshold more than a standard, music-accompanied work out, they told conference delegates.
Their experiments are further support that opioids are involved. "It's another piece of the puzzle," says Bowling. "You don't need a neuroscientist to tell you that music can be invigorating, intensely pleasurable or sad, but this is an exciting time for research on music's biological foundations."
Fritz is working on software that can provide similar "musical feedback" to users, which he says might help relieve pain for people recovering from strokes or drug addiction. Some hospitals already use music to relieve anxiety before surgery, and pain after. But Sven Bringman of the Karolinska Institute in Sweden says it could be used more. "Music is not used as much as it should be because it takes more of a nurse's time than just giving a sedative."
While music has yet to be fully exploited clinically, Levitin says we routinely take advantage of its effects on our brain. "Many people use music to regulate their mood throughout the day. We use music to create a soundtrack to our lives," he
