Air Pollution Linked to Fertility and Pregnancy Risks
Doctors are saying that air pollution is not just bad for our lungs and heart.
It can also make it harder for people to have babies and can cause problems during pregnancy.
Tiny particles in the air, like PM2.5, can hurt sperm and eggs, making it tougher to get pregnant.
For women who are pregnant, these pollutants can cause miscarriages, babies being born too early, or having low birth weight.
Even after birth, these pollutants can affect the baby's lungs and brain, making them more likely to have asthma or learning problems.
There's no safe level of pollution during pregnancy, so doctors are advising people to reduce their exposure as much as possible.
Long-term exposure to air pollution, particularly PM2.5, is linked to reduced fertility in both men and women.
Pollution triggers oxidative stress and chronic inflammation, damaging sperm DNA and ovarian follicles.
Pregnant women exposed to polluted air face higher risks of miscarriage, preterm birth, and low birth weight.
Pollution exposure during pregnancy can affect the baby's lung and brain development, increasing risks of asthma and cognitive challenges.
Doctors recommend minimizing pollution exposure, improving indoor air quality, and monitoring high-risk pregnancies closely.
