Air pollution tied to stroke, anxiety.
In addition to causing respiratory problems, air pollution is also associated with a higher risk of stroke, found a study published in March in The BMJ.
In a meta-analysis of more than 100 studies in nearly 30 countries, researchers found an association between carbon monoxide, sulphur dioxide, nitrogen dioxide and stroke-related hospital admissions and death. Specifically, the study found a 1.5 percent increased risk of stroke-related hospital admissions or death per 1 parts per million of carbon monoxide, a 1.9 percent increased risk per 10 parts per billion of sulphur dioxide, and a 1.4 percent increased risk per 10 parts per billion of nitrogen dioxide. Researchers found the association between pollution and stroke risk was strongest in low- and middle-income countries.
In a related study in the same journal, researchers found that exposure to air pollution known as fine particulate matter was also associated with a higher risk of anxiety. The study, which was based on data from the U.S. Nurses' Health Study, found that women who lived between 50 meters and 200 meters from a major road were more likely to have higher anxiety than those living more than 200 meters away. However, women who lived within 50 meters of a road did not experience an association between anxiety and air pollution.
