I believe music is therapeutic. I think it can help alleviate pain to some extent.
Below are a few quotes from scientific studies – and one from Bob Marley – that back me up here.
“Evidence from this review and other reviews suggests music therapy may be considered for clinical use.” Marianne J. E. van der Heijden, et el. 2015
“Music might be a simple, safe, and effective method of reducing potentially harmful physiologic responses arising from pain in patients after open heart surgery.” Nadiye Özer, et al. 2013
“Music intervention is safe, inexpensive and easily used to improve the healing environment for abdominal surgery patients.” Anne Vaajoki, et al. 2011
Music is “safe, inexpensive” and does actually help with the perception of pain.
“One good thing about music, when it hits you, you feel no pain.” -Bob Marley
