If you search for heavy metal in the National Library of Medicine database, most of what you find is on heavy metal contamination.

In fish, for example, making it so hard to clearly establish the role of fish in a healthy

diet, perhaps helping to explain that quintupling of odds of autoimmune diseases

like juvenile arthritis, for instance.

But searching the hazards of heavy metal also pops up entries like this on the risks

from heavy metal music.

Here they were talking about traumatic injuries from slamming around,

but you're more likely to get injured at an alternative rock concert.

It's the Goo Goo Dolls you've got to worry about, not nine-inch nails.

Okay, sure.

Music-induced hearing loss is a serious problem, but that can be from any loud music.

It's interesting. Clinical recommendations include the 80 to 90 rule, no more than 80% of the maximum volume on personal listening devices for no more than 90 minutes a day.

But that's not what the science shows.

Do not exceed 60% of the maximum volume, maybe more evidence-based,

but they figured teens would just ignore that,

so they came up with a more acceptable advice.

I assumed I'd see a lot of satanic panic nonsense from the 80s,

where parents bereaved by suicide started suing heavy metal musicians.

What kind of evidence did the parents present?

There's been little scholarly research until this study that proceeded to try to correlate

the number of statewide heavy metal magazine subscriptions

to youth suicide rates.
