During pregnancy a mother s immunity is low and so it is necessary that she takes certain precautions to keep herself safe. Too much exposure to smog can make her fatigued and restless and the pollutants in the air will make it difficult for her lungs to work to their full capacity.

How it affects the baby

There are studies that have indicated that prenatal exposure to smog can have an adverse respiratory effect in the babies. It can impair organogenesis and organ development, which can lead to long-term complications in the baby. Exposure to air pollution during pregnancy affects respiratory health in different ways. Lung development might be impaired by air pollution indirectly by causing lower birth weight, premature birth or disturbed development of the immune system. Exposure to air pollution during pregnancy has also been linked to decreased lung function in infancy and childhood, increased respiratory symptoms, and the development of childhood asthma.

In addition, impaired lung development contributes to infant mortality. The mechanisms of how prenatal air pollution affects the lungs are not fully understood but studies are suggestive enough to point out that smog does affect the unborn child in the womb [1].
