Just when you thought you covered all the potential risks to your pregnancy – unhealthy food, toxic paint, hair spray – one invisible danger still remains: air pollution.
While you never planned on writing “watch the air quality index” on your to-do list as a pregnant mum, that may just be a reality in today’s world.
With Singapore’s terrible air quality in recent years, air pollution may prove to be a greater threat to motherhood than we ever realised.
Pregnancy and Air Quality
Your body during pregnancy is doing more than you’d think.
To sustain new life, your lungs, heart and circulation have to work overtime: increased oxygen consumption, a faster heart rate and more blood pumped around.
These physiological changes make pregnant women more vulnerable to inhaled pollutants.
Worse, some studies show that pollutants don’t just stay in the lungs. They may cross into the placenta, influencing the baby’s growth.
So, the air you breathe matters. Not only for you, but for the tiny new life growing inside you.
And while “clean air” might sound like a luxury in the city, acknowledging the risk is half the battle.
The Risks of Air Pollution on Pregnancy
Several studies found that higher exposure to pollutants like nitrogen dioxide is correlated with babies born smaller (weight, head circumference, length).
More recently, a study from the U.S. found that air pollution around the time of conception and early pregnancy increased the risk of gestational diabetes.
Even relatively low pollution levels were linked to signs of intrauterine inflammation in the placenta.
That matters because inflammatory changes can ripple through foetal development – affecting respiratory health, neurodevelopment and more.
Studies also found maternal exposure to air pollution prior to and during early pregnancy raised the risk of congenital heart defects in offspring.
Should Expectant Mums Worry About Air Pollution?
Yes. That said, it’s not about inducing panic or suggesting you must seal yourself in a bubble. It’s practical, smart, and manageable.
Knowledge empowers: if you know polluted air is a risk factor, you can act accordingly.
Some exposure is avoidable, especially during high-pollution times or heavy traffic. You’re already managing other factors (nutrition, exercise, stress) – this just adds one more layer of care.
But it’s also important to remember that you can’t control everything. Living in a city means some exposure is inevitable.
Also, let go of the myth of “perfect” air equalling perfect pregnancy. These risks are probabilistic, not guaranteed. Avoid guilt trips: if you’re doing your best, that counts.
Incorporate “air quality” into the pregnancy toolkit rather than trying to eliminate it. Think of it as the third or fourth dimension of prenatal care (after food, rest, and doctor visits).
Should You Worry?
Here are some user-friendly, easy-to-apply ideas:
- Keep an eye on the air quality index (AQI) via apps or websites. On poor-air days, stay indoors more.
- Stay away from heavy traffic zones during your walks or fresh-air time. If you live near a busy road, consider pollution-filtering indoor plants or an air purifier.
- When you are outdoors during higher pollution, consider using a mask rated for fine particulates (where appropriate and comfortable for you).
- Ventilate your home when the air is cleaner (morning or after rain) and avoid indoor pollutants (smoke, strong fumes).
- Talk with your healthcare provider about your living environment and any particular risk factors you have (e.g., pre-existing asthma, high blood pressure).
- Continue the good work on diet: Antioxidant-rich foods may help counter oxidative stress from pollutants (though don’t think they “fix” high pollution exposure).
A Breath of Fresh Air?
Pregnancy is already a journey of many changes, physical, emotional and logistical.
Adding “air quality” into the mix might feel like another item on the to-do list, but it doesn’t need to be heavy.
The evidence is clear: what you breathe can influence what the baby receives. And while you can’t control the wind or the traffic precisely, you can work with the conditions.
By being aware, by adapting simple routines, you’re giving yourself and your baby a little extra protection – no white coat or huge expense necessary.
So, inhale less worry and exhale more preparation. After all, the only thing you want fluttering into the nursery is good dreams – not fine particulate matter.
