New Delhi: The level of pollution has been continuously increasing since last few days and now dense fog is also being seen in many areas. This dangerous mixture of pollution and fog is not only harmful for the health of common people, but can also pose serious risks to pregnant women and the child in their womb.

According to experts, polluted air and smog can directly affect the development of the baby in the womb. Especially there is a risk of harm to the child’s brain development. In view of this, pregnant women have been alerted to protect themselves from pollution.

What came out in the research?

According to research reports, both pollution and smog affect the child in the womb. Micro particles like PM2.5 and PM10 present in polluted air include nitrogen dioxide and carbon monoxide. These particles reach the lungs through breath and then dissolve in the blood and can reach the placenta.

The risk increases further for pregnant women who live in areas with high pollution. Research shows that these polluted particles can have a negative impact on the mental development of the child.

Newborn immunity and risk of respiratory diseases

Due to smog and fog, the risk of weakened immunity of the newborn also increases in pregnant women. Apart from this, the child also has a higher risk of developing asthma and other respiratory diseases in the future. This risk is seen to be higher in women who live in highly polluted areas.

Smog and fog are both dangerous

Experts say that along with pollution, fog in the morning is also equally dangerous. The poisonous particles present in smog enter the lungs along with the breath and cause harm to the body, due to which the health of both mother and child can be affected.

How should pregnant women protect themselves?

  • wear a mask when going out

  • Use air purifier at home

  • Avoid going out in the morning and evening

  • Take a balanced and nutritious diet as per doctor’s advice.
