As wildfires rage across parts of Spain, even if you can’t see the flames from your home, you might be unknowingly inhaling harmful particles produced as a result of combustion . The air quality in much of the peninsula has reached alarming levels, with some areas in Castilla y León, Galicia, and Asturias experiencing pollution levels that are over 40 times the limit set by the WHO . Simply stepping outside and breathing can be likened to smoking nine cigarettes .
Can Wildfire Smoke Affect Me?
Absolutely. The smoke from wildfires can travel hundreds of miles, and the harmful particles it generates can linger in the air for weeks. These fine particles are typically invisible to the naked eye as they measure less than 2.5 microns (for context, a human hair is about 80 microns thick), yet they pose a significant risk to our heart and lungs . If you’re wondering, you can still be exposed to these particles even when the air doesn’t smell like smoke.
How Dangerous is Contaminated Air?
Exposure to high levels of particles from wildfires significantly increases the risk of dying from a heart attack, stroke, or pneumonia within seven days of exposure . This concerning finding comes from recent research by the Barcelona Institute for Global Health , which analyzed reports from 32 European countries from 2004 to 2022. Furthermore, this contaminated air may contain benzene, formaldehyde, and sulfur dioxide —some of which are highly carcinogenic . Indeed, the smoke from wildfires is as lethal as the flames themselves.
Are Pregnant Women at Risk?
Certain harmful particles can enter the bloodstream when inhaled, posing a potential risk to the fetus. High exposure to smoke can increase the likelihood of premature birth or complications in areas where air quality is dangerously poor and precautions are insufficient. Prolonged exposure may lead to developmental issues in the baby, low birth weight , or high blood pressure in the mother.
Here are some key points to consider for protecting your health:
- Stay indoors while air quality is poor. Ensure all doors and windows are tightly closed, possibly using damp cloths to seal gaps.
- If you must go outside, wear a properly fitting FFP2 or FFP3 mask. Remember, surgical masks or cloth masks won’t filter out fine particles effectively, so limit your time outdoors.
- Avoid exercising outside.
- Air purifiers have gained popularity during the pandemic. These devices contain high-quality air filters capable of trapping particles smaller than 2.5 microns (PM 2.5), providing cleaner indoor air.
- Stay hydrated, use artificial tears, and perform nasal rinses with saline if you’ve inhaled smoke.
- If you have diagnosed respiratory issues like asthma or COPD, keep your prescribed rescue inhalers handy for emergencies.
Is Using Air Conditioning Safe?
Air conditioning units are equipped with HEPA filters , which can effectively capture contaminating particles. Therefore, using air conditioning can be a good option for cooling your home while preventing the need to open windows.
If you’re driving, you can also utilize the air conditioning system in recirculation mode to keep the air inside cleaner.
When Should I Seek Emergency Help?
It is wise to monitor for alarm symptoms . If they appear, contact emergency services to ensure that the roads are clear for your journey to the nearest emergency facility. Symptoms warranting medical attention include persistent coughing, chest pain, difficulty breathing, dizziness, high fever , or decreased fetal movement for pregnant women.
In summary, the threat posed by wildfires extends far beyond the flames themselves. From severe respiratory issues to potential long-term health effects, the widespread impact of air pollution should not be taken lightly. Awareness and proactive measures can be essential for safeguarding your health and that of your loved ones during such critical times. Stay informed, follow health guidelines, and prioritize your well-being.
