Breathing is an action that you, me, and everyone else does every day, all the time. We need to breathe to exchange gases with the outside world in order to live, and that's why air pollution affects our bodies so drastically. This is why air pollution affects our bodies so dramatically. But perhaps it's also because breathing is so simple, and done unconsciously every day, that many people overlook the fact that airborne pollutants are constantly causing harm to their bodies.
Many people are insensitive to air pollution because it doesn't seem like it's causing them much harm; it may just be a cough or two, or an itchy throat or nose that you just scratch. However, the real danger that air pollution poses to the human body is the damage that accumulates over a long period of exposure. Recently, more and more diseases have been confirmed to have an increased risk of occurring due to air pollution. The research evidence of the harmful effects of air pollution on the human body has only increased over time.
-Children's Intellectual Development - Research published in Neurology, a journal of the American Medical Association, suggests that air pollution may cause damage to the developing brain of the developing fetus, even as early as during pregnancy. The findings showed that the higher the exposure to polycyclic aromatic hydrocarbons (PAH), the smaller the area of white matter. In severe cases, prenatal exposure to high levels of PAH resulted in the virtual loss of white matter in the brain after birth.
Lung Cancer - The International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) has released a report stating that outdoor air pollution is an important contributor to cancer and classified it as an IARC Class 1 carcinogen. The report also emphasizes that the longer a person is exposed to air pollution, the greater the risk of lung cancer.
Heart - Disease A 10-year study by scholars at the University of Washington found that living in areas with high levels of air pollution may cause a buildup of deposits in the arteries of residents, increasing blood flow to the heart. The buildup of deposits in the coronary arteries may also accelerate the disease process of atherosclerosis, which can lead to heart attacks and increase the risk of other heart diseases.
Stroke - Air pollution, whether from indoor or outdoor sources, is a significant risk factor for fatal stroke, according to new research from the University of Washington. The authors suggest that air pollution may be linked to one-third of all strokes worldwide. Asthma - A study from the Icahn School of Medicine at Mount Sinai in New York found that children exposed to high levels of air pollution at birth had a 64% higher rate of wheezing with asthma symptoms, and that children exposed to high levels of pollution until the age of 7 years had a 71% higher risk of wheezing than other children. 71%, indicating that air pollution caused by vehicles has a significant impact on children's respiratory health, and that continuous exposure to polluted environments from age 1-7 years greatly increases the risk of asthma.
