Even Light Exposure To Air Pollution Can Cause High Blood Pressure

About one in three adults suffers from hypertension, which increases their risk for both disability and death from heart disease and stroke — both are among the leading causes of death in the United States. However, the causes of high blood pressure, a condition in which the force of the blood against the artery walls is too high, are complex and involve genetic and environmental factors, lifestyle, and diet.

The results showed that hypertension was significantly associated with short-term exposures to sulfur dioxide and particulate matter. It was also linked to long-term exposure to nitrogen dioxide, which is produced from combustion, and particulate matter. No significant associations were found between carbon monoxide and ozone on high blood pressure in the short term. Researchers said the potential connection between these pollutants and high blood pressure requires further study.
