Wildfire Smoke and Pregnancy: What You Need to Know

As wildfire season continues across the U.S., it’s worth understanding the risks for pregnant patients — especially with summer travel season underway. Connecticut has experienced poor air quality days from wildfire smoke in recent summers, and it’s worth understanding the risks if you’re pregnant, especially with summer travel season underway.

Why does this matter during pregnancy?

Per the EPA, exposure to wildfire smoke during pregnancy significantly increases the risk of preterm birth, low birth weight, and potentially long-term neurodevelopmental effects on the baby. The fine particulate matter in wildfire smoke is small enough to cross the placenta, which is why reducing exposure during heavy smoke events matters — both indoors and outdoors.

What to do when air quality is poor

  • Stay inside as much as possible, and keep windows and doors closed. If you have air conditioning, set it to recirculate rather than pulling in outdoor air, and use a portable air cleaner in your main living and sleeping spaces if you have one.
  • No AC or air cleaner, and conditions are bad? Call 211 to find a public shelter.
  • If you must go outside, wear a properly fitting mask, such as an N95 or KN95 — similar to what many of us used during COVID.
  • Avoid indoor cooking or other smoke-producing activities, like burning candles, on high-smoke days.
  • Know the signs of premature labor and contact your provider if you have any questions or concerns.

Traveling this summer?

Keep this in mind if your travel plans take you somewhere wildfire smoke is present, even if it’s not local to Connecticut. Air quality conditions can change quickly, so it’s worth checking local air quality reports for your destination before and during your trip.
