Metal music is a broad genre of rock music that is characterized by its use of distorted guitars, heavy drums, and aggressive vocals. While metal music is often associated with aggression and violence, there is a growing body of research that suggests that listening to metal music can actually have a calming effect on people who are feeling nervous or shy.
One of the reasons why metal music may have a calming effect is because it can help to release pent-up emotions. When people are feeling nervous or shy, they may feel like they are bottling up their emotions. Listening to metal music can provide a safe and cathartic outlet for these emotions, allowing people to express themselves in a way that they might not be able to do otherwise.
