In the study, participants were allowed to select music which made them feel good and brought them joy. Researchers found a healthy response that matches the response found by an earlier study on laugher. The music caused tissue in the inner lining of blood vessels to or expand which increased blood flow. Conversely, listening to music that was perceived as stressful caused their blood vessels to narrow, producing a potentially unhealthy response that reduces blood flow.
Music replaces laughter as best medicine
