Wildfires in Canada bring health concerns with persistent smoke exposure
Increased frequency and intensity of wildfires in Canada pose significant long-term health risks due to persistent smoke exposure.
Stephanie Cleland and Ryan W. Allen write for The Conversation.
In short:
- Wildfires in Canada have increased by 220% over the last two decades, threatening air quality.
- Long-term exposure to wildfire smoke is linked to premature death, reduced lung function and increased cancer risks.
- Persistent smoke exposure also affects cognitive function and prenatal health.
Why this matters:
Chronic exposure to wildfire smoke can lead to a variety of long-term respiratory issues. Conditions such as asthma and chronic obstructive pulmonary disease can be exacerbated, leading to more frequent and severe attacks. Even those without pre-existing conditions can develop new respiratory problems after prolonged exposure to these harmful pollutants. For vulnerable populations like children, the elderly and individuals with pre-existing health conditions, the risks are even higher.
