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.
