Road Traffic Noise Could Heighten Risk Of Hypertension: Study

The risk was found by researchers, to increase in tandem with the noise ‘dose’. These associations were found to be held true even when researchers adjusted for exposure to fine particles and nitrogen dioxide.

Living near a busy road can be a noisy and stressful experience. The sound of roaring engines, honking horns, and wailing sirens can make you feel as if your blood pressure is rising.

The study is been published in the Journal of the American College of Cardiology.

The Global Research

The researchers at the American College of Cardiology U.S. found this through a prospective study, conducted using UK Biobank data from more than 240,000 people aged 40-69 years, without hypertension at baseline.

Over a median period of 8.1 years, the scientists followed up with the participants for data on how many people developed hypertension. They estimated road traffic noise based on the residential address and the common noise assessment method, a European modeling tool, they mentioned in the study.

The scientists also found that people who had high exposure to both traffic noise and air pollution had the highest hypertension risk, showing that air pollution may play a role as well.

 “We were a little surprised that the association between road traffic noise and hypertension was robust even after adjustment for air pollution,” said Jing Huang, lead author of the study.

 “It is essential to explore the independent effects of road traffic noise, rather than the total environment,” said Huang.

The scientists suggested policymaking that may alleviate the adverse impacts of road traffic noise, such as setting stricter noise guidelines and enforcement, improving road conditions and urban design, and investing advanced technology in quieter vehicles.

Pathophysiological It means through hypertension develops from road noise is underway.
