We’ve reported numerous times about the respiratory health effects of pollution, but a pair of new studies are highlighting additional dangers of smog and particulate matter in the air we breathe.
The first study, conducted by Ryu Matsuo, M.D., a professor at Kyushu University in Fukuoka, Japan, drew correlations between airborne pollution and the chances of suffering a stroke during days with high levels of pollution in the air. By comparing data on 6885 cases of stroke and mapping where and when they occurred with an overlay of pollution readings, Matsuo found that increased levels of particulate matter in the air within one day of a stroke event coincided.
The conclusion: higher levels of PM2.5 concentrations in the air create higher chances that a person can suffer a stroke within a day of the elevated levels; PM2.5 refers to air pollutants with a diameter of 2.5 micrometers or less, which are small enough to invade airways.
The second study, conducted by King’s College London in the UK, found there was an increased risk of death after someone suffered a stroke if that person was exposed to high levels of air pollution before their stroke. Again, researchers compared stroke data with the levels of PM2.5 pollution in areas where the stroke victims resided—the higher the concentrations of pollution, the higher the risk of death after a stroke.
The studies underscore the importance of clean air for all—PM2.5 contaminants are present in indoor air was well as the outdoors. So, air purification, like that offered by the line of commercial-grade AeraMax® Professional line of air purifiers, is vital for health.
