We are fortunate to experience low levels of environmental pollution and excellent outdoor air quality most times of year. However, this past summer, Canadian wildfires resulted in several episodes of poor outdoor air quality. Poor air quality and elevated levels of pollutants can impact everyone, but especially the very young, older adults and those with pre-existing respiratory problems such as asthma or heart disease. When pollution levels are elevated, the New York State Department of Health recommends that individuals limit strenuous outdoor physical activity (such as walking instead of running) to reduce their risk of adverse health effects. Those with related healthcare concerns should consider contacting their healthcare provider. Visit Cornell’s new Outdoor Air Quality page for more information.
