The electromagnetic waves generated by music can make every cell of a person vibrate. At the same time, music can affect blood pressure and heart rate, and can also change a person's breathing frequency.

Unpleasant music can cause nausea, stomach cramps, and even loss of vision and taste.

Generally speaking, music with gentler melody makes people more relaxed, and their heartbeat and breathing are gentler, while fast-paced music naturally makes people's heart beat faster.

However, to have a beneficial blood vessel dilation effect, the choice of music type is not too important. As Professor Griffiths of the British Heart Foundation said: "One person's 'Mozart' may be 'Madonna' for another person.

"Different people find relaxation in different music." So feel free to pick and choose what you like, and it's good for your heart as long as you listen to the music you like.
