The perils of a loud lifestyle. I’m Bob Hirshon and this is Science Update.
Exposure to constant noise – even mild street traffic – may jack up your risk of a heart attack. This according to Stefan Willich and his colleagues at the Charité University Medical Centre in Berlin, Germany. They found that a noisy home environment increased heart attack risk by 50 percent in men, and tripled the risk in women. It didn’t matter if the noise actually bothered the patients – only that it was above 60 decibels.
STEFAN WILLICH (Charité University Medical Centre, Germany):
In the environment, that would be a street with rather quiet traffic – you know, a few vehicles per minute, not a very busy road.
In addition, workplace noise increased heart attack risk for men, but not for women. He says it’s not clear if the gender differences are environmental or biological.
