Is bushfire smoke bad for your health? Bushfire smoke has continued to intermittently shroud some of Australia's major cities as bushfires rage around the country.
Sydney has said goodbye to blue skies as a blanket of haze, of varying degrees of thickness, has made life unpleasant for some and downright dangerous for others over the summer period. Canberra's smoke haze was so bad at one stage that it briefly overtook Asia's polluted megacities in the air pollution stakes, and the National Gallery had to close to protect priceless artworks from being damaged by all the smoke particles in the air.
In Melbourne, the smell of smoke peaks when the wind dies down and the temperature rises, causing smoke bands higher in the atmosphere to descend on the city and suburbs. In January, residents were breathing smoke from fires burning in East Gippsland, along with smoke from NSW and from as far away as Western Australia, said the state's chief health officer, Brett Sutton. Bushfire smoke harms the lungs like cigarette smoke. Bushfire smoke can damage the lungs in a similar way to smoking-related emphysema, according to a study from the Woolcock Institute of Medical Research.
Published in international science journal PLOS ONE, the study found that breathing in smoke from burning wood and other biological materials – known as biomass fuels – can scar and inflame the lungs, increasing the risk of risk of developing chronic obstructive pulmonary disease (COPD). COPD is the umbrella term for lung diseases including emphysema, chronic bronchitis and chronic asthma, and affects one in 13 Australians aged 40 and over.
Cigarette smoke is the primary cause of the disease. The researchers measured inflammation and scarring on human lung cells using tissue from 26 donors. The tissue was exposed to increasing concentrations of biomass smoke extract, collected from a burning tree, over 72 hours. “It would be incorrect to say that someone who has been around a bushfire once is going to develop a horrible disease. Pregnant women should take extra care to minimise their exposure to bushfire smoke. Smoke haze from Australia’s catastrophic bushfires is continuing to affect many parts of the country.
Although there’s no safe level of air pollution, the health hazards tend to be greatest for vulnerable groups. Alongside people with pre-existing conditions, smoke exposure presents unique risks for pregnant women. Research shows prolonged exposure to bushfire smoke increases the risk of pregnancy complications including high blood pressure, gestational diabetes, low birth weight and premature birth (before 37 weeks). These conditions can have short-term and lifelong effects on a baby’s health, with increased risk of conditions including cerebral palsy and visual or hearing impairment.
Even babies born only a few weeks early can experience learning difficulties and behavioural problems, and have an elevated risk of heart disease in later life. Our buildings aren't made to keep out bushfire smoke. Here's what you can do. In early December 2019, a Sheffield Shield cricket match between NSW and Queensland was played in bushfire smoke so thick that the ball was at times invisible to the spectators.
Since then, the rest of us have become far more aware of the hazards of bushfire smoke, and authorities have become more active in reminding us how dangerous it can be, especially during exercise. A standard piece of advice is to “spend more time indoors”. But does it work? Up until this year, with bushfire smoke lasting only a few days, it was good advice, especially for buildings that rely on recirculated and filtered mechanical ventilation complying with Australian Standard 1668 Part 2. These buildings include shopping malls, cinemas, hospitals, larger offices and some of the buildings in some universities.
It’s fine in cinemas, for a while… Staff. From face masks to air purifiers: what actually works to protect us from bushfire smoke? Bushfire smoke has now been blanketing parts of Australia for months.

Beyond being stifling and unpleasant, people are experiencing irritated eyes and breathing difficulties. Statistics emerging from hospital records show an increase in emergency hospital admissions for a range of diseases from asthma to heart disease and stroke. We’ll only fully understand the longer term health effects in the weeks and months to come. When the situation is as bad as it has been in Sydney over the past few days, people stop asking questions about whether air pollution has an impact on health; we know it has.

Doctors for the Environment Australia is today joining a coalition of Australia’s major health and medical groups in declaring hazardous air pollution from bushfire smoke in Sydney and other areas in NSW a public health emergency.
The groups are also linking the fires to climate change.

Is bushfire smoke bad for your health? Poor air quality caused by bushfire smoke posing serious risk for healthy people too, health experts warn - Health - ABC News. Doctors are warning even healthy people could develop serious illnesses, because of the smoke haze that's blanketed parts of the country, including some of our major cities, for weeks on end.
The Australian Medical Association (AMA) has warned prolonged exposure to toxic smoke could affect the health of many Australians. In a statement released late last week, AMA president Tony Bartone described the length and density of smoke exposure as "a new, and possibly fatal, health risk" most of us have never faced before. "With denser smoke haze and longer periods that people endure smoke inhalation, there is a much higher risk that previously healthy people will face developing serious illness," Dr Bartone said. Australia's bushfire crisis has killed at least 20 people, destroyed or damaged at least 2,000 homes, and led to emergency declarations in two states. Air quality in Canberra recently reached more than 22 times the hazardous rating.
