A recently published Danish study indicates that traffic noises may increase the risk of stroke, particularly for older individuals.
Risk of stroke
The study was published in the European Heart Journal and looked at the association between road traffic noise and stroke in more than 51,000 Danish people. It was found that for every 10-decibel increase in noise level, the risk increased by 14 percent. In those over 65, the risk of stroke increased by 27 percent.
Traffic noise has been linked with an increased risk of heart attacks and high blood pressure in previous studies. However, this study is the first to examine the connection between traffic noise and stroke. The increase in risk was most significant for noises louder than 60 decibels.
