How Does Indoor Air Pollution Affect Expecting Mothers?

We spend about 90% of our time indoors; hence, common indoor pollutants such as carbon monoxide, sulfur dioxide, and nitrogen dioxide can affect your pregnancy. Recent research indicates that air pollution can adversely impact your pregnancy; hence, it may be time to look at your HVAC system. While the HVAC system can help with air quality, a dirty system can make you breathe unhealthy air. Here is how indoor air pollution can affect you during pregnancy.

It Can Lead to Preterm Birth

If your baby is born earlier than the 37th week, he or she is considered preterm. Preterm delivery puts your baby at risk of physical disabilities, brain disorders, breathing, and heart problems. While there are many causes for premature births, one of them is indoor air pollution, which you can avoid.

Studies have shown a relationship between indoor air pollution and preterm birth. About 18% of all preterm births could be linked to air pollution.

Low Birth Weight

After birth, a healthy baby usually weighs between six and nine pounds. Health experts consider any weight that is less than five pounds during delivery as low.

Several studies have shown the impacts of air pollution on a baby's birth weight. One major study indicated that expectant mothers living in polluted regions delivered babies who weighed an average of 0.69 pounds less than those delivered in less contaminated areas.

Autism Spectrum Disorder

The Harvard School of Public Health indicated that pregnant women exposed to air pollution in the third trimester were twice at risk of delivering a baby with an autism spectrum disorder. The researchers found that the risk of your baby contracting the disease was significant in the third trimester.


You do not have to worry about asthma affecting your pregnancy if it is well controlled. However, having uncontrolled asthma when pregnant can result in premature delivery, pre-eclampsia, or high blood pressure.

It doesn't matter how well you have managed to control asthma; air pollution can worsen the symptoms. Additionally, research has indicated that exposure to air pollution during pregnancy can increase the probability of your baby developing asthma.

You can avoid many things that may affect your health and baby's health during pregnancy. Do not let indoor air pollution deprive you of the chances of a blissful delivery, and happy child. Contact Robert Bair Plumbing Heating and Cooling for more information on how we can fix your HVAC system.
