Recently, many regions have experienced varying degrees of smog, with nearly half the country affected by haze. During smoggy weather, severe air pollution significantly disrupts daily life. So what risks does smog pose to expectant mothers and their fetuses?
Smog-laden air contains microscopic dust-like particles invisible to the naked eye, yet these tiny particles are invisible health threats. As smog intensifies, various benign and malignant diseases follow. Though many fear smog, people gradually adapt after repeated exposure.
How does smog affect pregnant women and fetuses?
1. Increased risk of congenital heart disease
Women exposed to polluted air during pregnancy, especially in the second month, face a higher likelihood of their children developing severe congenital heart defects.Studies also reveal that children born to mothers exposed to severely polluted air are three times more likely to develop heart disease than those born to mothers with normal exposure levels. 2. Potential Impact on Fetal Weight and Cognitive Development Prolonged exposure to high concentrations of PM2.5 during pregnancy may disrupt normal fetal development, leading to smaller head circumference and lower birth weight in newborns. It may also impair fetal brain development, potentially resulting in reduced IQ.(Recommended reading: Expectant mothers should protect their eyes during pregnancy!)
Studies indicate that PM2.5 exhibits a stronger correlation with increased mortality than PM10. For every 10-microgram-per-cubic-meter increase in PM2.5 inhalation, infant mortality from preterm birth rises by 1%. For children already born, it may cause intellectual impairment.
3. Hypertensive Pregnant Women May Experience Premature Birth
During hazy weather, poor air circulation and quality can elevate blood pressure and cause anxiety in some pregnant women. Those with pre-existing hypertension are particularly prone to developing gestational hypertension or preeclampsia under such conditions.
Simultaneously, smog can cause intrauterine hypoxia, leading to increased fetal movements. Prolonged exposure may also trigger excessive anxiety, extreme fatigue, and excessive abdominal pressure in pregnant women, further agitating the fetus and causing intense activity. Excessive fetal movements can increase the risk of preterm birth.
Understanding the dangers of smog, it is crucial for expectant mothers who cannot avoid it to know how to minimize its harm.(Recommended Reading: What Calcium Supplements Should Pregnant Women Take?)
1. Wear a mask when going outdoors
Masks effectively prevent harmful airborne substances from entering the respiratory system. This is especially important for pregnant women with asthma, as masks significantly reduce the amount of pollutants entering their lungs and nasal passages.
PM2.5 masks generally come in three protection levels: 90%, 95%, and 99%. Higher protection levels mean greater resistance to normal breathing, making it harder to breathe. For daily commutes or occasional outings, an N90 mask is sufficient and allows for relatively smooth breathing.
2. Minimize Window Opening Time
Many believe opening windows allows air to circulate.However, opening windows during hazy weather only allows harmful substances to enter the room. When doors and windows are closed, indoor air pollution becomes more severe, easily triggering respiratory diseases.
Therefore, during hazy weather, it's best to open windows only when the sun appears. If the weather remains hazy or overcast all day, it's best not to open windows at all.Of course, rooms occupied by pregnant women and infants should be kept exceptionally clean, eliminating any hygiene blind spots to prevent bacterial growth. Bedding should also be changed promptly.
3. Increase indoor humidity
During smoggy days, the air is filled with dust, sulfur dioxide, and other harmful substances that float freely. Sprinkling water on the floor can help trap these particles.
Therefore, it's advisable to place a humidifier in rooms occupied by pregnant women and infants, or use damp clothing and towels to absorb these pollutants. Simultaneously, promptly wipe dust from room appliances and tabletops.

Simultaneously, promptly wipe dust from electrical appliances and tabletops. 4. Dietary Adjustments Consume foods that clear the lungs and remove dust, opting for light, easily digestible meals. Key lung-cleansing foods include white radish, carrots, purple cabbage, pears, and lily bulbs.Drink plenty of water to prevent respiratory infections and protect mucous membranes.
5. Indoor Activities Expectant mothers should avoid morning exercises. Early morning smog occurs when atmospheric pressure is low and oxygen levels are reduced, potentially causing chest tightness. Additionally, cold morning air can irritate the body, and inhaling it may strain the heart.Accelerated metabolism may cause increased intake of harmful substances. Therefore, indoor activities like yoga are recommended for comfort and gentle exercise.(Recommended reading: Winter Wellness Tips for Pregnant Women to Support Baby's Healthy Growth)
6. Supplement Vitamin D Appropriately
Smoggy weather means less sunlight, which translates to reduced UV exposure. This can lead to insufficient vitamin D levels in the body. If a pregnant woman experiences low energy or mood swings, supplementing with vitamin D is advisable. Good sources include cereals, cod liver oil, and egg yolks.
7. Add Green Plants
Consider growing aloe vera, Clivia, or rubber plants on balconies or near windows indoors. These large-leafed, green-crowned plants are ideal for home cultivation due to their strong adsorption capabilities, effectively trapping airborne particles.
Finally, regardless of the weather, maintaining a positive mindset and an optimistic attitude is crucial for both the baby and the mother!
