The sound of horns, sirens and noisy trucks may take a toll on your blood vessels, according to a recent study that found an association between traffic noise and risk of stroke.
The results, based on surveys of more than 51,000 people in Denmark, showed that for every 10-decibel increase in noise level, the risk of stroke increased by 14 percent. For those over 65, the risk of stroke increased 27 percent.
The exposure to loud noise may increase the body’s stress hormone levels, and increase blood pressure, which might contribute to the uptick in stroke risk, the researchers said. The study was published Jan. 26 in the European Heart Journal. Previous research had also linked traffic noise with an increased risk of heart attacks.
