As wildfires become more frequent and intense, many of us are finding ourselves checking the air quality index (AQHI) more often than the weather. Smoke from forest fires doesn’t just obscure the sky—it poses serious health risks, especially for those with asthma, heart conditions, or young children. Here’s how you can stay safe and healthy when wildfire smoke is in the air.
Not Just About Lungs: What Healthcare Professionals Need to Know About the Wide-Ranging Impacts of Wildfire Smoke
Wildfire smoke is no longer an occasional summer nuisance — it’s a recurring public health threat with implications far beyond the respiratory system. This article summarizes current evidence on systemic effects, emerging risks, and patient counseling strategies, based on recent Canadian and international research.
- Primary Pollutants & Mechanisms
- PM2.5 particles can cross into the bloodstream, reaching all organs.
- Can cross the blood–brain barrier, raising neurological concerns.
- Cognitive & Neurological Impacts
- Links to increased dementia risk and short-term cognitive decline.
- Potential role in epilepsy development.
- Cancer Risk
- Long-term exposure linked to lung cancer and brain tumours.
- Fetal & Neonatal Health
- In utero exposure linked to higher rates of respiratory infections in infancy.
- Endocrine & Metabolic Effects
- Emerging evidence of links to diabetes onset and management challenges.
- Mental Health
- Associated with worsening of depression, anxiety, and mood disorders.
- Cardiovascular Risks
- Similar to other air pollution sources, but spikes in exposure may have unique impacts.
- Clinical Guidance
- Encourage indoor air quality control, patient action plans, and awareness of real-time air quality data.
- Balance risk communication to avoid unnecessary anxiety.
- Policy & Systems Approach
- Advocate for legislative changes to improve indoor air quality and protect vulnerable populations.
Check the Air Quality Health Index (AQHI) Daily
Before you head outside, check the AQHI for your area. Here’s the link to the Government of Canada’s air quality observations for Ottawa and Orleans.
- 1–3 (Low Risk): Ideal conditions for outdoor activities. No special precautions needed.
- 4–6 (Moderate Risk): Consider reducing or rescheduling strenuous outdoor activities if you are at risk.
- 7–10 (High Risk): Reduce or reschedule strenuous activities, especially if you are at risk.
- 10+ (Very High Risk): Avoid strenuous outdoor activities. Everyone should take precautions.
How to Protect Yourself When the Air Quality Health Index is High
Stay Indoors When Smoke Levels Are High
If the AQHI is high, stay indoors as much as possible. Close all windows and doors and run your HVAC system if you have one. Make sure your air system uses high-quality HEPA filters to trap fine particulate matter (PM2.5).
Pro Tip: Create a “clean room” in your home with an air purifier for extra protection.
Use a HEPA Air Purifier
Invest in a portable HEPA air purifier for your home or office. These can dramatically reduce indoor air pollution caused by wildfire smoke. Make sure it’s rated for the size of the room where you plan to use it.
Wear a Proper Mask Outdoors
Cloth and surgical masks won’t protect you from fine smoke particles. Use an N95 or P100 respirator for real protection. Ensure a snug fit and avoid prolonged exposure outdoors, even with a mask.
Avoid Physical Activity Outdoors
Exercising outdoors when the air is smoky forces you to breathe more deeply, drawing dangerous pollutants further into your lungs. Opt for indoor workouts or take rest days during high-smoke periods.
Keep Your Indoor Air Clean
- Don’t burn candles or incense
- Avoid frying or broiling food
- Vacuum with a HEPA filter
- Avoid smoking indoors
Every bit of pollution you can reduce indoors matters when the outside air is compromised.
Watch for Symptoms
Smoke exposure can cause:
- Coughing or sore throat
- Shortness of breath
- Chest pain
- Eye, nose, and throat irritation
If you or a loved one has trouble breathing or experiences worsening symptoms, contact a healthcare provider immediately.
Prepare for Wildfire Season in Advance
Don’t wait until the smoke rolls in:
- Keep a supply of N95 masks
- Replace HVAC filters early in the season
- Buy an air purifier in advance (they often sell out during wildfire events)
