why can listening to slow music slow breathing
Research. A study by British and Italian researchers published in Heart magazine shows that listening to fast, upbeat music accelerates respiration and heart rate, while listening to slow, meditative music has a relaxing effect, slowing breathing and heart rate.
If the carbon dioxide concentration gets too high, then both types of chemoreceptors signal the respiratory centers to increase the rate and depth of breathing. The increased rate of breathing returns the carbon dioxide concentration to normal and the breathing rate then slows down.
