    Bushfire smoke can worsen heart and lung conditions such as angina and emphysema (chronic obstructive pulmonary disease).

    This may lead to symptoms such as chest pain, shortness of breath or heart palpitations, and may increase the risk of heart attacks.

    Things you can do to protect your health:

    • talk to your doctor about managing your heart or lung condition when there is bushfire smoke, including completing any action plans you should follow
    • know the symptoms to watch out for and when to seek medical advice or call Triple Zero (000)
    • visit ​ Heart Foundation - Bushfire smoke and your health for further information.​
    ​

  • If you are pregnant, you may be more sensitive to the effects of smoke.

    Brief exposure to bushfire smoke during pregnancy is unlikely to affect you or your baby. If you are continuously exposed to smoke for more than one week, it may increase the risk of outcomes such as preterm birth, lower birth weight and developing gestational diabetes.

    Things you can do to protect you and your baby:

    • talk to your doctor or midwife about managing your health when there is bushfire smoke about
    • take steps to reduce your exposure to all sources of smoke during pregnancy
    • know what to do if the air quality is impacted by bushfire smoke in your area.

  • ​Children are more vulnerable to the effects of smoke because they spend more time outdoors engaged in physical activity, have developing airways and breathe more air relative to their body weight.

    It is important to reduce your child’s exposure to bushfire smoke.

    Children with lung conditions, such as asthma, may be more sensitive to smoke.

    Things you can do to protect your child:

    Childcare centres are also encouraged to monitor air quality for their local area and follow the health advice to protect children from bushfire smoke.

    Learn more on protecting yourself and others from bushfire smoke​.

    If children in your care display symptoms of asthma such as difficulty breathing, a wheeze or persistent cough, follow their written Asthma Action Plan. If they do not have a plan, provide asthma first aid​, contact their parents or carers and monitor the child closely. Call Triple Zero (000) if symptoms are not improving or get worse. ​​​​

    During an emergency, your body processes glucose differently.

    Stress, changes in physical activity and the food you eat, may mean you need to adjust your medication during and after a bushfire emergency.

    Things you can do to protect your health:

    • talk to your doctor about managing your diabetes when there is bushfire smoke or during a bushfire
    • ask your doctor to help you prepare a diabetes management plan
