what if pregnant woman in enclosed car with smoking smell for 30 minutes, but did open all windows a bit. Will this harm the baby

Exposure to secondhand smoke can potentially be harmful to both a pregnant woman and her unborn baby. Even if the windows were opened slightly, being in an enclosed space where smoking occurred can expose the mother and baby to harmful chemicals found in tobacco smoke. Cigarette smoke contains various toxic substances, including nicotine, carbon monoxide, and tar, which can affect fetal development and increase the risk of complications such as low birth weight, preterm birth, and developmental issues. While opening the windows may help reduce the concentration of smoke in the car, it may not eliminate the risk entirely, especially if the exposure was significant. If a pregnant woman finds herself in such a situation, it's important to talk to a healthcare provider for personalized advice and to discuss any potential concerns. Additionally, minimizing exposure to secondhand smoke is crucial for the health of both the mother and the baby.
