Wildfire Smoke More Dangerous Than Other Air Pollution for People With Asthma
July 26, 2021
Stage 2 Air Quality Index and alarming research studies from DRI, Renown Health and the Washoe County Health District leads to public health advisory- seek care if needed
For people who suffer from asthma, wildfire smoke is more hazardous than other types of air pollution, according to a study from the Desert Research Institute (DRI), the Renown Institute for Health Innovation (Renown IHI) and the Washoe County Health District (WCHD). The study published in the journal Environmental Health examined associations between airborne particulate matter (PM) from sources such as wildfire, transportation and industry, and medical visits for asthma at Renown Health’s emergency departments and urgent care centers in Reno, Nev. during the six-year period from 2013-2018.
In places like Reno, where wildfire events occur regularly during parts of the year and are expected to become more frequent in the future, an accurate understanding of the impacts of wildfire smoke on population health is critical. We have an exceptional process in place through our urgent care sites, Renown Medical Group offices and hospital emergency departments to screen, diagnose and treat members of our community who come to us for care related to asthma, chronic obstructive pulmonary disease (COPD), chronic bronchitis, emphysema, and other upper respiratory diseases that may be exacerbated by wildfire smoke. At the same time, we continue to develop and refine, in real-time, the data that supports our predictive analytic models. We are using every tool and resource-including scientific data and clinical reporting, to ensure that we are meeting both the health and healthcare needs of the people we serve.
In the study, researchers found that air quality in the Reno area was affected by wildfire smoke on a total of 188 days during the study period. A total of 18,836 asthma-related emergency room and urgent care visits occurred over the same five-year period of time, indicating that the influences of wildfire smoke and other types of air pollution on this medical condition are important to understand.
The Washoe County Health District – Air Quality Management Division (AQMD) has issued a Stage 2 Air Pollution Warning due to smoke from area wildfires. Air quality in the Reno-Sparks area is now “Very Unhealthy” with an Air Quality Index of 247. The Stage 2 warning means that all residents should stay indoors and reduce activity levels due to the susceptibility of increased health risks. To see current air quality in Reno-Sparks, click here.
Brion Hill, MD who practices at the Renown Urgent Care - Los Altos location warns, “This is an important health advisory, exposure to elevated PM2.5 (fine particulate matter in smoke) concentrations can result in eye and throat irritation, headaches, nausea, shortness of breath, congestion, coughing, impaired lung function and chest pain. Everyone should take precautions when the air quality is unhealthy. Air pollution can aggravate heart and cardiovascular disease as well as lung diseases like asthma and COPD. When the air quality is unhealthy, people with these conditions may experience symptoms like chest pain, shortness of breath, wheezing, coughing, or fatigue. If you are experiencing any of these symptoms, use your inhalers as directed and contact your health care provider,” says Dr. Hill. “If you do not have a health care provider, we have 11 conveniently located Renown Urgent Care offices with providers ready to see you 7 days a week."
Dr. Joseph Grzymski, a research professor at Desert Research Institute, a corresponding author on the study and Chief Scientific Officer, Renown Health, says, “This air is very bad for your health. Given today’s Air Quality Index in Reno, being outside and breathing this air for a day equals about smoking half a package of cigarettes.”
