Delhi woke up under a thick layer of smog on Thursday morning as the city’s air quality plunged sharply overnight, falling into the ‘very poor’ category. The cloud seeding experiment to trigger artificial rain failed to bring relief. According to data from the Central Pollution Control Board (CPCB), the capital’s overall Air Quality Index (AQI) reached 352, which is an increase of nearly 80 points from Tuesday’s average. Surrounding areas such as Noida, Ghaziabad, and Gurgaon also recorded ‘very poor’ air quality. As authorities rush to manage the crisis, residents continue to experience breathing troubles and other health concerns caused by the toxic air. Doctors warn that the effects of this pollution are especially dangerous for pregnant women. Medical experts across fields say this “toxic winter” goes far beyond coughing and watery eyes, as it is damaging multiple systems in the body, including those of unborn children.Delhi Air Pollution Worse For Pregnant WomenPregnant women and their babies are especially vulnerable to the impact of polluted air due to physiological changes that occur during pregnancy. A woman’s oxygen consumption increases by about 20%, minute ventilation rises by 40% to 50%, and cardiac output goes up by roughly 40%. These shifts cause higher intake of air pollutants, which can travel through the bloodstream, cross the placenta, and reach the developing fetus. This may interfere with normal growth and development, according to a study published in Nature.Newborns face an even higher risk since their immune systems and organs are still developing. Their fragile bodies are not equipped to manage the toxic load from air pollution.Several pediatricians warn that poor air quality can have lasting effects on children’s health. Some studies suggest that babies exposed to pollution in the womb may have a higher likelihood of childhood obesity. Early exposure may also contribute to diseases linked to immune dysfunction, such as asthma.Delhi Air Pollution: Factors That Increase Risk for Pregnant Women and ChildrenImmune dysfunction: Polluted air can alter immune function, leading to inflammation and allergic responses.Epigenetic changes: Pollution can interfere with gene regulation, potentially leading to long-term health effects.Oxidative stress: Airborne toxins can trigger oxidative stress, damaging cells and tissues in both the mother and the baby.Delhi’s pollution problem is no longer a temporary nuisance—it has turned into a chronic health crisis. While using air purifiers and masks can help temporarily, experts say sustainable solutions must involve cleaner fuels, better public transport, and strict control on emissions. Until then, awareness, prevention, and regular health check-ups remain the most effective forms of protection.Tips to Protect Yourself and Your Baby from Air PollutionCompletely avoiding pollution is impossible, but as per Dr. Ranjeet Singh, Professor And Hod General Medicine Niims Medical College And Hospital, you can take a few steps to limit your and your baby’s exposure.1. Track air quality regularlyCheck your local Air Quality Index (AQI) through websites like airnow.gov. It provides real-time information on how polluted the air is, possible health effects, and safety precautions.2. Stay indoors when pollution levels are highEven with a mask, pollutants can still affect your body. On days with poor air quality, avoid outdoor exercise and limit time spent outside, especially if you have asthma or allergies. Consider using an air purifier at home to reduce harmful particles.3. Avoid smoke exposureKeep your home and car smoke-free. Stay away from places where people smoke, as second-hand smoke adds to indoor pollution. If you are a smoker, pregnancy is the best time to quit. Stopping now protects both you and your baby.
