Negative health effects from the chronic inhalation of polluted air are well known to cause cardio-respiratory disease. It can be particularly damaging to seniors, children, and people with asthma. Now according to a study from Ohio State University, breathing polluted air can also cause widespread inflammation by triggering the release of white blood cells from bone marrow into the blood stream. The influx of white blood cells can alter the integrity of the blood vessels. The white blood cells are then absorbed into fat tissues where chemicals are released that cause inflammation.
