Teens listening to head-banging heavy metal music are at greater risk of depression and suicide, researchers have cautioned.
According to the Melbourne University paper, early intervention at schools is necessary before behavioural problems start.
Dr Katrina McFerran's study which spanned five years, found that heavy metal music leads to mental illness in some teens aged between 13 and 18.
"Most young people listen to a range of music in positive ways; to block out crowds, to lift their mood or to give them energy when exercising, but young people at risk of depression are more likely to be listening to music, particularly heavy metal music, in a negative way," the Herald Sun quoted McFerran as saying.
McFerran also said that people who listened to the same song or album of heavy metal music were in the highest risk category.
"If this behavioural continues over a period of time then it might indicate that this young person is suffering from depression or anxiety, and at worst, might suggest suicidal tendencies," she said.
Other music genres including rap, rock and pop did not have the same results as heavy metal.
