Wood fires and breathing problems

wood fires breathing problems

Smoke from slow combustion stoves, wood fires, burn offs and bushfires can cause breathing problems.  Wood fire smoke can pollute the air with carbon monoxide – an invisible, odourless and tasteless gas that, once ingested, can cause confusion, headaches, fatigue, damage to the heart and brain, and death. Particles in wood fire smoke can irritate the eyes, throat, nose and respiratory system.

Wood smoke may also contain carcinogenic pollutants like benzene, butadiene, formaldehyde and polycyclic aromatic hydrocarbons. Exposure to these gases can severely hinder healthy development and damage the respiratory, nervous, reproductive and immune systems.

The effects of wood smoke exposure are typically short-term, with most healthy adults recovering quickly. Children, however, as well as elderly persons and individuals with a diagnosis or history of heart disease, lung conditions, diabetes, and high blood pressure, are particularly susceptible to smoke-induced breathing problems.


Inside the home: wood heater, slow combustion stoves, outdoor smoke entering the house.

Outdoors: outdoor fires (at your own or neighbour’s home), burning off, bushfires.

Things to consider if you use a wood heater or wood stove:

  • Operate it properly and clean the flue or chimney regularly to minimise the amount of smoke produced.
  • Only use good quality wood – make sure the wood is dry and has no paint on it. Try to use smaller logs rather than one large log.
  • Leave a window partially open to let in fresh air and reduce the build-up of indoor pollution.
  • Maintain a bright flame and never let your heater smoulder to ensure enough heat for complete combustion.
  • Clean your chimney every year.
  • Be aware of signs like drowsiness, an indication that carbon monoxide levels are high.
