If you live near a busy intersection, consider soundproofing your home. Noises generated by road traffic may increase the risk of stroke in people age 65 and older. Danish research found that every 10-decible increase in noise, the risk of having a stroke increased 27% overall for those aged 65 and over.

Previous research had linked traffic noise with increased blood pressure and risk of heart attacks. The recent Danish study adds the accumulating evidence that traffic noise may cause a range of cardiovascular diseases.

Why traffic noise?

Noise is a stress and can disturb sleep which results in increases in blood pressure and heart rate. The older you get, the more fragmented sleep becomes, making you more susceptible to the sounds outside your bedroom.
