Story summary

A Finnish study in Environmental Research links living near busy roads to higher depression and anxiety.
The researchers analyzed 114,353 individuals aged 8 to 21 in the Helsinki area, tracking diagnoses through 2016.
For each 10-decibel increase in road noise, depression rose 5% and anxiety 4%.
The association was stronger in males and among those without a family history of mental disorders, but it remains an association, not causation.
