Noise and the increased risk of serious stroke

This report in Science Daily describes a fascinating study done in Barcelona. The study found that patients who lived in noisy areas suffered worse strokes than those who didn’t. Patients who lived in quieter areas near green zones, on the other hand, had less severe strokes.

Only this report and the abstract, published in Environmental Research, are available outside a pay wall, so I can’t comment on the scientific methods used in the study, but Environmental Research is a well regarded, peer-reviewed scientific journal. And the study results are consistent with past experience.

Hypertension is a well-known risk factor for stroke, with higher blood pressures being associated with more severe strokes. The Barcelona report supports other studies, including human, animal, and epidemiology studies, showing that noise exposure increases blood pressure due to autonomic nervous system and hormonal stress responses to noise. I suspect that is the likely explanation for the new study’s findings.
