Health Impacts
How do wildfires affect the cardiovascular health of exposed people?
Inhalation of fine particulate matter and toxic gases can induce systemic inflammation, oxidative stress, and increased blood pressure, which increases the risk of heart attacks, arrhythmias, and strokes.
Why do developing countries face greater challenges in mitigating the public health effects of wildfires?
They have less infrastructure for early detection, limited resources for healthcare, and less capacity to implement prevention and rapid response strategies.
Is the public health impact of forest fires given priority in the media, or only the material and environmental damage?
The media generally emphasise the loss of infrastructure and biodiversity, while the effects on human health tend to receive less attention, despite their long-term severity.
What steps can governments take to reduce public exposure to wildfire smoke?
Implementing early warning systems
Distributing masks
Promoting clean air shelters
Improving forest management to reduce the risk of fires.
What psychological and psychiatric impacts can people affected by wildfires suffer?
They may experience post-traumatic stress, anxiety, depression, and sleep disorders due to the trauma of evacuation, loss of property and loved ones, and uncertainty about recovery.
What socioeconomic factors make certain populations more vulnerable to the health effects of wildfires?
Poverty, lack of access to medical care, location in fire-prone areas, and scarce resources for evacuation or protection exacerbate the vulnerability of these communities.
What role do social media play in disseminating information about the health risks of forest fires?
They are key tools for disseminating alerts and protective measures in real time, but they can also spread misinformation if sources are not verified.
How can urban planning help minimize the impact of wildfires on public health?
Designing buffer zones between residential areas and forests, using fire-resistant materials in construction, and improving evacuation routes.
Is there a relationship between exposure to fine particulate matter (PM2.5) during wildfires and the increase in chronic diseases such as cancer?
Yes, PM2.5 can penetrate deep into the lungs and bloodstream, increasing the risk of lung cancer, cardiovascular disease, and impaired immune function.
How do wildfire prevention and response policies vary between high- and low-income countries?
High-income countries often have advanced monitoring technology, specialized brigades, and warning systems. In low-income countries, lack of funding and training limits effective response.
How can media coverage contribute to prevention and awareness of the health effects of forest fires?
Through information campaigns on air quality, protective measures, symptoms of exposure and the impact of climate change on the frequency of fires.
How can education and awareness-raising reduce health risks associated with wildfires?
Through campaigns on the dangers of smoke, first aid in case of exposure, and how to reduce the likelihood of human-caused fires.
How can wildfires contribute to the emergence and spread of infectious diseases?
Forced displacement due to fires can lead to overcrowding in shelters, increasing the transmission of respiratory diseases and infections. In addition, water pollution and ecosystem disturbances can favour the spread of pathogens.
What impact do wildfires have on indigenous and rural communities compared to urban areas?
Indigenous and rural communities are more dependent on the ecosystem for their livelihoods, so fires affect their livelihoods, water sources, and food security. They may also have less access to emergency services and medical assistance.

How can climate change policies help prevent wildfires and their long-term health impacts?
By reducing greenhouse gas emissions, promoting reforestation and adapting forest management to a changing climate to reduce the intensity and frequency of fires.
