Bushfire smoke is a mixture of different-sized particles, water vapour and gases, including carbon monoxide, carbon dioxide and nitrogen oxides.
The larger particles in bushfire smoke contribute to the visible haze when a fire is burning. They are generally too large to be breathed into your lungs, but may irritate your nose and throat.
The finer, microscopic particles and gases in bushfire smoke can be breathed into your lungs and cause health problems.

Planned burns are designed to protect life, property and the environment. Planned burns reduce bushfire risk by reducing the amount of fuel for bushfires and keep plants and animals healthy.
Smoke from planned burns can affect your health in different ways, depending on your age, pre-existing medical conditions (such as asthma or heart disease), and the length of time you are exposed to the smoke.
To minimise any possible health effects of smoke from planned burns:
- Wait until the planned burn is over before you exercise or do long periods of physical activity, especially outdoors.
- Stay indoors, if possible, and keep windows and doors closed.
- Switch air conditioners to ‘recirculate’ or ‘reuse’ air. If they don’t have that function, turn them off.
- Take an air-conditioned break at a local library or shopping centre if your home gets uncomfortable and it’s safe to do so.
- Continue to take your medicine as prescribed by your doctor if you have a heart or lung condition.
- If you are an asthmatic, follow your personal asthma management plan, and keep a reliever or inhaler on hand.
Look out for signs of short-term smoke irritation, such as itchy eyes, sore throat, runny nose and coughing. These will usually clear up in healthy adults once you’re away from the smoke.
If you have a heart or lung condition (including asthma)and develop symptoms such as shortness of breath, coughing, wheezing or chest pain, follow your prescribed treatment plan. If symptoms do not settle, see you doctor.
