Living in noisy and polluted zones amplified the risk of hypertension.” Senior author Kazem Rahimi, professor of cardiovascular medicine and population health at the University of Oxford, told CNN: “Because areas that are noisy tend to have a high level of air pollution as well, one question that arises is whether each are independently contributing to risk and this was indeed the case. Higher noise level, higher hypertension risk People living near road traffic noise were not only more likely to develop high blood pressure, but the risk of this outcome increased with the “dose” of noise, even when researchers adjusted for fine particles and nitrogen dioxide. The results, published Wednesday in the journal JACC: Advances, surprised researchers. The team from the American College of Cardiology used residential addresses and a European modeling tool, the Common Noise Assessment Method, and looked at follow-up data over a median of 8.1 years to see how many people developed high blood pressure. Using health outcome data from biomedical database UK Biobank, which contains genetic and health information from half a million UK participants, researchers analyzed data from more than 240,000 40- to 69-year-olds who did not initially have hypertension. Now, researchers say they have the evidence for it. Previous research had shown a connection between road traffic noise and an increased risk of hypertension - high blood pressure - but it was still unclear whether it was the noise or the pollution from the traffic that was the cause. ![]() But the honking of horns and revving of engines doesn’t just affect those in the vehicle - it can also raise the blood pressure of people living near the road. ![]() ![]() (CNN) - Most of us are familiar with road rage - aggressive driving that’s caused by stress or anger behind the wheel.
