A Swedish study says a quarter of European people live near roads where noise levels are likely to raise blood pressure to risky levels. A team from the University of Lund found that the risk of high blood pressure rose by more than 25% with noise levels above 60 decibels, putting them at risk of heart disease and stroke. The studay, which was based on a sample of just under 28,000 people, is published in the Environmental Health Journal.
