A massive plume of smoke rises from wildfires burning in Gippsland, Australia. When a wildfire rages, the flames are the biggest threat. But the really small particles can bypass these defenses and disturb the air sacs where oxygen crosses over into the blood. So even in an individual who does not have underlying allergies or does not have an underlying respiratory condition can certainly feel the effects of the irritant and can develop some symptoms particularly cough and sometimes some shortness of breath with exertion and those sorts of things.

There, the particles can harm a person's respiratory and cardiovascular systems, increasing the risk of heart attack, stroke and infection. Initial evidence indicates that continuous (i.e., over multiple days) occupational wildland fire smoke exposure may have a cumulative effect on lung function, with some studies reporting a progressive decline during burn seasons (e.g., Adetona et al. "Every person who asks me is like, 'What does this mean for my health a long time from now?,'" says Colleen Reid, a geographer at the University of Colorado Boulder who studies the health impacts of wildfire smoke.

The smoke released by any type of fire (forest, brush, crop, structure, tires, waste or wood burning) is a mixture of particles and chemicals produced by incomplete burning of carbon-containing materials. Health effects associated with exposure to wildfire smoke and fine particulate matter (PM2.5) include short- and long-term premature mortality, hospital admissions, emergency department visits . We aimed to identify long-term baseline epigenetic changes associated with early-life exposure to wildfire smoke. Although particle pollution is a principal public health threat from short-and longer-term exposure to wildfire smoke, it is important to keep in mind that wildfire smoke is a complex mixture that consists of other pollutants that have also been shown to lead to a variety of health effects.

Even in healthy people, exposures to fine particles can potentially lead to transient reductions in lung function, and pulmonary inflammation. Wildfire smoke is a mix of gases and fine particles from burning vegetation, building materials, and other materials. Before While the wildfires have caused immediate damage by gutting homes and towns, experts say that a few weeks of smoke exposure should not have long-term side effects for most healthy people. The examination of persistent short-term exposures to wildfire smoke(i.e., exposures over a series of days up to a few weeks) has been limited to a few epidemiologic studies examining the cumulative effect of wildfire smoke exposure on the health of wildland firefighters (Adetona et al. And while the chemical content of wildfire smoke may not always differ substantially from other types of smoke, wildfires are a totally different kind of event by nature; the smoke can travel far and fast, cloaking urban areas in a toxic blanket that can sometimes be seen from space.
