The experiment group did also perceive less stress and had lower levels of the stress hormone cortisol. The more the participants in the survey study liked the music, the less stress they experienced.
But it should be pointed out that when studying emotional responses to music it is important to remember that all people do not respond in the exact same way to a piece of music and that one individual can respond differently to the same piece of music at different times, depending on both individual and situational factors.
To get the positive effects of music, you have to listen to music that you like,' says the author of the thesis Marie Helsing.
