According to a 2015 study, listening to heavy metal music can help combat emotions like anger and depression.
Leah Sharman from the University of Queensland School of Psychology has conducted this research and says "When you're angry and you listen to something that's highly arousing, it's going to match your emotional state". 39 heavy metal fans were induced anger by talking about irate topics, then they listened to 10 minutes of heavy metal followed by 10 minutes of silence. This actually put heavy metal listeners in a calmer state of mind. Sharman's research has led to numerous studies being conducted on this topic.
