The Air Inside Your Home Matters: How Wildfire Smoke Can Affect Your Health

Over the past several summers, smoke from Canadian wildfires has drifted into Pennsylvania and many surrounding states.

Even though the fires may be hundreds of miles away, their effects can still be felt locally through reduced air quality and hazy skies.

While most people think about limiting time outdoors, many don't realize that wildfire smoke can also impact the air inside their homes.

What Is Wildfire Smoke?

Wildfire smoke is a complex mixture of gases and microscopic particles produced when trees, vegetation, and other materials burn. One of the greatest health concerns is PM2.5, tiny particles measuring less than 2.5 micrometers in diameter.

Because these particles are so small, they can bypass the body's natural defenses and travel deep into the lungs. Some may even enter the bloodstream, where they can contribute to inflammation throughout the body.

Who Is Most at Risk?

Although anyone can be affected, certain groups are more vulnerable, including:

• Infants and young children

• Older adults

• Pregnant women

• Individuals with asthma or COPD

• People with heart disease

• Anyone with weakened immune systems

Common Symptoms

Exposure to wildfire smoke may cause:

• Coughing

• Wheezing

• Shortness of breath

• Sore throat

• Burning or watery eyes

• Headaches

• Fatigue

• Worsening allergy symptoms

• Increased asthma attacks

If you experience chest pain, severe shortness of breath, dizziness, or symptoms of a heart attack or stroke, seek emergency medical care immediately.

Why Indoor Air Quality Matters

Many people assume they're protected once they go inside. Unfortunately, smoke particles can enter homes through small gaps around windows and doors, ventilation systems, or whenever doors are opened.

Without proper filtration, indoor air may become nearly as polluted as the air outside.

Tips for Cleaner Indoor Air

Fortunately, several simple steps can reduce your exposure:

• Keep windows and doors closed when air quality is poor.

• Run your HVAC system using the highest-rated filter your system can safely accommodate.

• Replace HVAC filters regularly.

• Use a portable HEPA air purifier in bedrooms and living areas.

• Avoid burning candles or wood fires during smoke events.

• Reduce vacuuming if your vacuum does not have a HEPA filter, as this can stir up fine particles.

• Check the Air Quality Index (AQI) before spending extended time outdoors.
