Research exposes prolonged impact of traffic pollution on blood pressure

WEB DESK: In a recent study published in the Annals of Internal Medicine, researchers reveal alarming findings about the tangible effects of traffic-related air pollution on blood pressure, comparable to the impact of smoking or high salt intake.

The study, led by Dr Joel D. Kaufman from the University of Washington, focuses on the quantifiable consequences of exposure to pollutants commonly found in traffic emissions, such as carbon dioxide and particulate matter from brakes and tires.

The research indicates a significant rise in blood pressure following exposure to “traffic-related air pollution,” persisting for an entire day after the initial contact.

Particularly concerning is the identification of ultrafine particulate matter, currently unregulated, as a growing public health concern.

Dr Kaufman explains that the complex systems regulating blood pressure seem to be influenced by traffic-related air pollution, leading to potential long-term effects on heart and lung health.

To understand the impact of pollution during commutes, researchers conducted a unique study involving participants driving in Seattle’s morning rush hour.

The experiment, involving both filtered and unfiltered drives, revealed that exposure to pollution raised diastolic and systolic blood pressure, with effects lasting for 24 hours.

The study underscores the importance of considering the broader health implications of air pollution, advocating for cleaner air to combat cardiovascular risks associated with traffic-related pollutants.

Experts, including Dr Robert D. Brook from Wayne State University, emphasise the urgent need for reducing exposure to traffic-related air pollution, highlighting its significant role in cardiovascular diseases.

The study aligns with previous research revealing the global health threat posed by fine particulate pollution.

In summary, the research adds weight to the evidence linking traffic-related air pollution to cardiovascular risks, urging collective efforts to promote cleaner air and combat this serious global health concern.
