Study: Traffic noise linked to heart problems

Posted:

A new study links loud traffic noise to heart problems. Researchers in Denmark followed more than 50,000 adults over age 50 for a decade. They found those who lived with higher levels of traffic noise had higher risks for a heart attack. The exact link is less clear. Some experts suggest the increased traffic and noise might promote stress, air pollution and even a poor night's sleep.
