NO, NO, NO NO NO!

I could see that. certain frequencies could be present at high enough levels to damage some type of cell or molecule.
Don't ask me which ones, but sound is a physical thing, that's why we can measure and perceive it.

Among their speculation for causes is stress reaction.  We behaviorally grow accustomed, calm towards stressors, but that doesn't mean our physiology does.  The continuous exposure, over years, to stress through noise impacts cardiac and endocrine function.

It might be that noise directly impacted brain function.  It could be that impacts to other systems effected brain health.  Or, it could be something else.

The study focused on road and railway noise.  I wonder what the same observational study around large airports would find.

i 100 percent can see that.  I've lived right behind an interstate for 15 years; it interrupts my sleep constantly even though I tune it out during the day.

even worse, being any place that is dead silent at night is almost just as jarring at this point.  Once I get to year 5 of no house payments, I am moving away from here. thats...only 5 and a half years away.

If it is, it would be worth comparing to studies in other nations.  Denmark has some of the least income inequality in the world.

Denmark also has universal healthcare, meaning no matter how poor you are, you can get treatment for issues like blood pressure and diabetes for free.

This study would lend credence to noise causing immediate dysfunction in the brain. (exacerbated by schizophrenia) I can see how brains subjected to frequent and persistent dysfunction throughout their lifetime could deteriorate.

Right.  There's been so many of these types of stories amped up by the press with suggestive headlines in the last few years.. "People who use 'X' found to more often die of 'Y'.
It's all feeling more and more like clickbait.

If I smoke weed, that joint isn't going to necessarily make me die of a heart attack in the next 30 days... but the burgers/munchies I stuff in my mouth after smoking said weed probably isn't going to help (or the stress that I may be using weed to try to alleviate)

anyway, point is: Correlation != Causation.

That was part of the Rat Utopia experiment.  It produces quite a few papers on different social topics.   The stress ones were the rats were so stressed by their lives that they started showing odd behavior.

Causation has been shown between background noise and stress responses though. And it isn't a secret that stress is bad for your health.

"Correlation isn't causation" is something people throw around way too often.

I almost always feel that way about life expectancy data.  There are some things that matter, but most of it feels to me like it's far more whether someone can do X rather than whether they do do X.

Reducing noise and light pollution would go a long way in cutting down on urban stress.  During the height of the lockdown, there was almost no noise from machinery in my neighborhood.  It was really relaxing outside, even during the middle of the day.  The end of noisy ICE vehicles cannot come soon enough in that regard.

Now if we could just do something about all of these really bright LED streetlights going in.
