What can reduce stress in everybody – young, old, men, and women? Hearing classical music played LIVE! A study in the journal Public Health found people who attended a concert had significantly lower levels of the stress hormone cortisol. And that was even true for people who didn’t usually go to concerts or weren’t familiar with the music being played. It’s partly because classical music has been shown to lower heart and breathing rates… and partly because experiencing the same thing with others makes us feel part of a community – and that social support reduces stress.
