Exposure to loud traffic noise can increase your risk of having a heart attack, a Danish study has indicated.
Researchers say that for every 10% rise in noise volume, there is a a 12% higher risk of having a heart attack.
The study, involving over 50,000 people who had no previous history of heart disease, found a strong relationship between traffic noise and heart attacks. The researchers measured traffic noise based on where the participants lived.
Over 10 years, there were 1,600 first-ever heart attacks identified and they were elikely to occir among people living in areas with higher levels of traffic noise.
The Researchers from the Danish Cancer Society said that the reason for the link was not yet known, but they speculated that it could be due to due to high stress levels and sleep interruption associated with loud traffic noise.
Dr Mette Sorenson, of the Danish Cancer Society said: "in this study, residential exposure to road traffic noise was associated with a 12 per cent higher risk of myocardial infarction (heart attack) per ten decibel exposure to noise, showing a clear dose response relationship."
