Wildfires can destroy homes, businesses and entire communities. However, even people far from an active wildfire may experience health effects from the smoke that spreads through the air.
Wildfire smoke contains a mixture of gases, chemicals and fine particles that can travel hundreds of miles from the source. Depending on air quality conditions, exposure to wildfire smoke can affect healthy individuals and be especially concerning for children, older adults and people with underlying health conditions.
Understanding how wildfire smoke affects the body can help individuals take steps to protect themselves during wildfire season.
What Is Wildfire Smoke Made Of?
Wildfire smoke is created when vegetation, buildings and other materials burn. The resulting smoke contains a variety of substances, including:
- Fine particulate matter (PM2.5)
- Carbon monoxide
- Volatile organic compounds (VOCs)
- Nitrogen oxides
- Other chemicals that might be harmful
Fine particles known as PM2.5 are especially concerning. These particles are small enough to enter the lungs and, in some cases, pass into the bloodstream.
How Does Wildfire Smoke Affect Your Health?
Even short-term exposure to wildfire smoke can cause symptoms in some individuals. Common symptoms may include:
- Coughing
- Sore throat
- Eye irritation
- Runny nose
- Headaches
- Fatigue
- Shortness of breath
The severity of symptoms often depends on air quality levels, the length of exposure and an individual's overall health.
Who Is Most at Risk From Wildfire Smoke?
Certain groups may be more vulnerable to the effects of wildfire smoke than others. These include:
Children
Children breathe more air relative to their body size than adults and may spend more time outdoors, increasing potential exposure.
Older Adults
Older adults may be more susceptible to respiratory and cardiovascular issues associated with poor air quality.
People With Asthma or Lung Disease
Symptoms of asthma, chronic obstructive pulmonary disease (COPD) or other respiratory conditions can get worse during periods of heavy smoke exposure.
Pregnant Individuals
Research continues to examine how wildfire smoke exposure may affect pregnancy outcomes and fetal development.
People With Heart Disease
Fine particulate matter could place additional stress on the cardiovascular system and increase health risks for some individuals.
Can Wildfire Smoke Cause Long-Term Health Problems?
Researchers continue to study the long-term effects of wildfire smoke exposure. Occasional exposure may cause temporary symptoms, but repeated or prolonged exposure may increase the risk of respiratory and cardiovascular issues.
Studies have linked wildfire smoke exposure to:
- Reduced lung function
- Worsening asthma symptoms
- Increased emergency room visits
- Respiratory infections
- Cardiovascular complications
The extent of long-term effects often depends on the intensity and duration of exposure.
How Can You Protect Yourself From Wildfire Smoke?
When wildfire smoke affects your area, public health officials may recommend limiting outdoor activities. Additional protective measures may include:
- Monitoring local air quality reports
- Keeping windows and doors closed
- Using high-efficiency air filtration systems
- Running air conditioners in recirculation mode when appropriate
- Avoiding strenuous outdoor exercise
- Wearing a properly fitted N95 respirator when necessary
Individuals with underlying health conditions should follow guidance from their healthcare providers during periods of poor air quality.
What Air Quality Levels Are Considered Unhealthy?
Air quality is often measured using the Air Quality Index (AQI). As AQI levels increase, health risks can also increase. The general measurements are:
- 0–50: Good
- 51–100: Moderate
- 101–150: Unhealthy for sensitive groups
- 151–200: Unhealthy
- 201–300: Very unhealthy
- 301+: Hazardous
Monitoring local AQI reports can help individuals make informed decisions about outdoor activities during wildfire events.
Wildfires Can Affect Communities Far Beyond the Flames
Many people assume wildfire smoke only affects those living near an active fire, but smoke can travel long distances and impact air quality across entire regions. Even communities hundreds of miles away from a wildfire may experience unhealthy air conditions when smoke concentrations become significant.
Understanding the risks associated with wildfire smoke can help to recognize symptoms, protect vulnerable family members and take appropriate precautions when air quality deteriorates.
Wildfire FAQ:
How Far Can Wildfire Smoke Travel?
Wildfire smoke can travel hundreds or even thousands of miles from the source of a fire. Depending on weather patterns and atmospheric conditions, smoke from large wildfires may affect air quality in communities far from the active burn area.
Can Wildfire Smoke Affect Healthy People?
Yes. While children, older adults and individuals with existing health conditions can face greater risks, wildfire smoke can also cause symptoms in otherwise healthy individuals. Exposure may lead to coughing, throat irritation, headaches, eye irritation and shortness of breath.
How Do I Know If Air Quality Is Unsafe?
Many communities and the Environmental Protection Agency provide air quality information through the Air Quality Index (AQI). As AQI levels increase, the potential health risks associated with outdoor exposure also increase.
Is Wildfire Smoke Worse Than Regular Air Pollution?
Wildfire smoke often contains high concentrations of fine particulate matter (PM2.5), which can penetrate deep into the lungs. During active wildfire events, smoke levels may cause air quality to deteriorate significantly and create health concerns beyond typical day-to-day air pollution levels.
Can Wildfire Smoke Affect Pets?
Yes. Pets can experience many of the same effects of wildfire smoke as humans, including coughing, respiratory issues and eye irritation. Pet owners may want to limit outdoor activity during periods of poor air quality and consult a veterinarian if symptoms develop.
When Should You Seek Medical Attention?
If you experience severe symptoms such as difficulty breathing, chest pain, persistent coughing or worsening respiratory conditions during a wildfire smoke event, seek medical attention promptly.
Healthcare professionals can evaluate symptoms and recommend appropriate treatment based on your individual circumstances. In some situations, wildfires can cause more than health concerns, leading to property damage, displacement and other losses.
