How Does Indoor Air Pollution Affect Expecting Mothers?

Expecting Mothers

Pregnancy is always a time for joy and expectation for expecting parents. A primary rule of pregnancy for expectant mothers is to remain healthy, not only for them but also for the baby. Expectant mothers should be wary of the quality of the air they breathe. Since they spend most of their time indoors, expectant mothers should be aware of the invisible threats present in the air.

Studies conducted have shown that breathing polluted air can adversely affect expectant mothers and their babies. Now that you are expecting, how about taking a look at your HVAC system? A well-maintained HVAC system gives you several benefits, including improved ventilation and indoor air quality. By maintaining your HVAC system, you protect yourself and your baby from the adverse effects of air pollution.

The Effects of Indoor Air Pollution on Pregnancies.

Low birth weight

A baby born weighing less than 5 pounds 8 ounces is considered as having low birth weight. A healthy full-term baby should be born weighing between 6 and 9 pounds.

Several studies have been conducted on the effects air pollution has on birth weight. One study conducted in Los Angeles reported that mothers living in polluted environments gave birth to babies who were 0.69lbs lighter than those born to mothers living in a clean environment.

Preterm birth

Preterm births are babies born before the 37th week of gestation. These babies are usually at the risk of many health problems, including neurological disorders and physical disabilities. A preterm birth could happen because of several reasons, but one you can avoid is air pollution.

Several studies have reported a connection between air pollution and preterm births. A Swedish study showed an association between exposure to ozone during the first trimester of pregnancy and preterm births. Similarly, according to the National Institute of Health, if you expose yourself to polluted air during a second pregnancy, the chances of preterm birth increase.


Asthma is a deadly condition to an expectant mother and her baby. However, if it is controlled, it presents no significant risk. Nevertheless, breathing polluted air can worsen a person’s asthma symptoms, whether or not they are under medication.

Breathing clean air is crucial for expectant mothers. In 2016, a study showed that exposure to air pollution during pregnancy increased the likelihood of the baby developing asthma later in life.
