Wildfire smoke continues to filter throughout certain regions of the U.S. and neighboring Canadian provinces. The repercussions are impacting air quality in those regions potentially triggering respiratory health issues thousands of miles away.
“The composition of wildfire smoke includes various pollutants, with ultrafine particles posing the most significant threat possessing the ability to infiltrate deep into the lungs, triggering inflammation and exacerbating pre-existing respiratory conditions,” says Mark Norton, M.D., a pulmonologist and critical care physician at Mayo Clinic Health System in La Crosse. “This array of respiratory irritants, including hydrocarbons and other organic chemicals, can induce a spectrum of symptoms ranging from coughing and wheezing to chest tightness and shortness of breath.”
Beyond the respiratory system, the adverse health effects of wildfire smoke extend to cardiovascular health, a facet often overlooked. Dr. Norton underscores the potential for fine particulate matter to infiltrate the bloodstream, eliciting systemic inflammation and exacerbating cardiovascular conditions.
“Individuals with pre-existing heart disease or hypertension may experience symptoms such as chest pain, palpitations, and fatigue in response to elevated levels of wildfire smoke,” he warns.
Recognizing the heightened vulnerability of certain populations, Dr. Norton emphasizes the need for tailored preventive measures.
“Children, whose developing respiratory systems are particularly susceptible to environmental pollutants,” says Dr. Norton. “I have little kids myself, and trying to keep them cooped up inside isn’t nearly impossible, especially with this great weather that we’re having. The idea here is to be aware of what the weather conditions are and what the air quality is. If it’s kind of marginal, it’s okay to let them go outside and have some fun, but maybe limit that exposure. If the air quality is bad, it’s a good idea to maybe find an alternative activity that might allow them to stay inside.”
The elderly who may have compromised lung function and reduced tolerance to respiratory stressors require special attention during wildfire events or even when the weather gets warmer.
“Moreover, individuals with pre-existing respiratory conditions such as asthma, COPD, and bronchitis face an elevated risk of experiencing exacerbated symptoms and respiratory distress,” Dr. Norton shares. “This is a great opportunity to be just a good neighbor, a good family member. If you have a neighbor who suffers from some lung condition or they’re on oxygen, just check in with them and make sure that they’re doing okay. If they need some assistance with maybe going to the store to help them avoid being outside.”
Amidst the escalating frequency of wildfires driven by climate change and environmental factors, Dr. Norton advocates for proactive public health strategies.
“Monitoring air quality indices and heeding advisories to limit outdoor activities on days of poor air quality are crucial steps in minimizing exposure to harmful pollutants,” he advises. “Indoor environments equipped with filtered air conditioning systems offer a sanctuary from the pervasive smoke, providing a haven for vulnerable individuals.”
Health effects of breathing in smoke may include:
Coughing
Trouble breathing normally
Stinging eyes
Scratchy throat
Runny nose
Irritated sinuses
Wheezing and shortness of breath
Chest pains
Headaches
Asthma attack
Tiredness
Fast heartbeat
For those managing chronic respiratory conditions, Dr. Norton stresses the importance of preparedness and collaboration with healthcare providers.
“Ensuring a sufficient supply of medications, including rescue inhalers and controller medications, is paramount for managing respiratory symptoms during wildfire events,” he emphasizes. “Establishing personalized action plans that outline steps for symptom management and escalation of care can empower individuals to navigate the challenges posed by wildfire smoke exposure.”
Dr. Norton underscores the imperative of public education and collective action in mitigating the health risks associated with wildfire smoke.
“In the past, it probably wasn’t as big of a concern because we didn’t have many of these poor air quality days. As time has gone on with climate changes and the pretty mild winter that we just had, we might see more of these wildfire conditions,” says Dr. Norton.
“It might be a good idea to start making this part of your daily routine,” adds Dr. Norton. “Just like we check to see what the weather is going to be, check the air quality index to decide if you might need to avoid going outside. Just like you carry an umbrella, think about carrying personal protective equipment like a 95-respirator mask, which does a great job filtering out those small particles and can help mitigate exposure to these different types of things.”
By fostering awareness, implementing preventive measures, and fostering resilience within communities, individuals can safeguard their respiratory health amidst the looming threat of wildfires.
