Traffic Noise Might Give You a Heart Attack
Louder streets have been linked to greater risk of cardiac arrest.
This just in from the Traffic Kills Department: researchers have found that exposure to the sounds of car traffic significantly increases the risk of heart attack.
Looking at people who've suffered heart attacks and the traffic noise levels in their neighborhoods, a team of Danish researchers found that heart attacks were more likely to occur in noisier areas. For every 10 decibels of increase in traffic noise, the risk of heart attacks rises 12 percent. Their results were published recently in the journal PLoS ONE.
