Road Noise, Traffic, and Blood Pressure

Does Road Noise and Traffic Affect Blood Pressure?

A new study from JACC (Journal of the American College of Cardiology) shows that road noise and traffic can be a stressor, and actually raise your blood pressure over time! There were previous studies that looked at this issue, but wasn't completely conclusive. Additionally, there were questions as to whether it was the Road Noise vs Air Pollution of traffic in general that played a role in rising blood pressure. Air pollution has certainly been linked to rising BP levels, but it appears that the disruptive noise levels of traffic and everlasting HONKING may increase blood pressure levels as well. In fact, the noise and air pollution may work synergistically to increase blood pressure in people.  

Should we look closer at how we build housing and developments near roads and highways? 

Air pollution from traffic can contain a range of harmful substances, including particulate matter, nitrogen oxides, and carbon monoxide. These pollutants can enter the bloodstream and cause inflammation and oxidative stress, which can damage blood vessels and increase blood pressure.

Noise pollution from traffic can also be a significant contributor to high blood pressure. Exposure to constant or intermittent noise from traffic can lead to increased stress and cortisol levels, which can cause blood vessels to constrict and lead to hypertension.

Also, spending long periods sitting in traffic can contribute to a sedentary lifestyle, which is a risk factor for high blood pressure. Regular physical activity is essential for maintaining healthy blood pressure levels, and a lack of activity can have negative consequences for cardiovascular health.

Several studies have found a link between living near highways or other sources of high traffic and an increased risk of high blood pressure. For example, a study published in the Journal of the American College of Cardiology found that people living within 100 meters of a major road had a 10% higher risk of developing high blood pressure compared to those living more than 1000 meters away.
