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).
