Navigating bumper-to-bumper traffic, especially en route to crucial appointments or the airport, can elevate blood pressure, a phenomenon not solely tied to external stressors, but also linked to poor air quality within the car. In a groundbreaking randomized crossover trial by University of Washington researchers, sitting in traffic and breathing unfiltered air led to a surprising 4.5 mm Hg surge in blood pressure, peaking at 60 minutes and persisting for up to 24 hours.
Lead researcher Joel Kaufman, a physician and professor at UW, emphasized the intricate mechanisms regulating blood pressure and suggested that traffic-related air pollution interferes with this complex system. To address this health concern, IQAir introduces the Atem Car—an innovative solution designed to combat the impact of traffic-related air pollution on cardiovascular health. In the study, a high-efficiency particulate air (HEPA) filter, blocking 86% of particulate pollution, significantly reduced the blood pressure surge.
Traffic-related air pollution (TRAP), the primary cause of air quality variation in US metropolitan cities, often contains high levels of ultrafine particles, known for their adverse health effects. Despite low ultrafine particle levels during the study, the HEPA filter effectively removed traces before entering the car, hinting at the potential importance of ultrafine particles in blood pressure elevation.
While the precise mechanism in TRAP triggering blood pressure elevation is not fully known, the researchers meticulously eliminated other confounding factors. IQAir's Atem Car emerges as a crucial tool to mitigate the cardiovascular risks associated with traffic-related air pollution. By incorporating advanced filtration technology, the Atem Car ensures clean and healthy air inside the vehicle, providing a transformative solution for millions facing similar daily commutes.
