Well, it may depend on the song.
It became apparent to me as i was getting off all medications that music was affecting my nervous system in a bigger way than I ever imagined. I was already aware that music affected my mood or helped me get more work done, depending on the type of music I played. But I never realized that even the slightest stressful song was pulling on my system and creating a negative effect in my body. I don’t shy away from that now because I know I should not shield myself but it was just good information for me to learn. It may be that we all have music that “sings to us” on a deeper level. There is a soothing joy that I get from Bob Marley. He is the soundtrack to my life (and why i walk around with a goofy smile on my face most of the time). Someone is singing to me in a way that is completely nourishing and apparently setting off a bunch of different things in my brain to create joy and pain relief.
“In particular, music expressing contentment, no matter what its genre, was found to be most effective in reducing the experience of pain…Because the experience of pain is partially subjective, altering a person’s perception of their pain can change their experience of that pain. Music may disrupt the brain’s “pain – stress – pain” feedback loop and in doing so alter an individual’s sensitivity to pain. How might this work? We know that music effects evolutionarily old subcortical areas of the brain, thereby influencing many different psychological and physiological states. Music modulates the brain’s limbic system, triggering numerous accompanying neurochemical effects. The result of these changes in the brain may be to help distract listeners from negative feelings and modify the influence of past memories associated with pain. As a further result, music may promote relaxation by inhibiting the release of stress hormones and weakening arousal of the pituitary-adrenal stress axis. The brain’s opioid system may also play a role. Music that listeners find emotionally engaging seems to affect the brain’s opioid system, and opioids control both physical pain and the pain of social loss.”
