According to researchers at Manchester University, music fans are stimulating part of the inner ear known as the sacculus, which responds to the beat in music. This gives the brain pleasure and makes us feel good — during the music and afterwards.
[When loud music is playing,] the brain is stimulated into releasing feelgood hormones that make us calm, happy and responsive. So to trigger a dose of happy hormones on a Monday morning, you should, in theory, choose Black Sabbath over chamber music.
This is fantastic news! Now I have a health related reason to rock out to Black Sabbath.
