Road Traffic Noise and Heart Attack Risk

Heart attacks more common with higher traffic noise levels over 10 years.

Researchers in Denmark have found that chronic exposure to traffic noise may increase the risk of a heart attack--independent of air pollution levels. Although they were unable to establish this as a cause of heart attacks, they found that for every 10-decibel (dB) increase in traffic noise near home, the risk of having a heart-attack was 12% higher. Perhaps there is wisdom in the words of Isaiah: “Keep silence before Me, O coastlands, and let the people renew their strength!" (Isaiah 41:1).

Does Road Noise Raise Stroke Risk?

Exposure to noise from residential road traffic is connected with higher stroke risk.

Living in noisy environments appears to predict higher stroke risk, according to Danish researchers. Risk rose a significant 14% for every 10 dB increase in residential exposure to traffic noise and nearly doubled among those over 65 years old (possibly because it might disturb their sleep). These effects remained significant in this observational study even after controlling for blood pressure and antihypertensive medication use. (Each 10 dB increase nearly doubles "loudness".) 

PositiveTip: Whenever possible, retreat to a quiet noise-free place for thinking and sleeping.
