New studies have been revealed that show just how much of an impact climate change and pollution have on human lives. Moreover, the study took a look at the impacts of air pollution on the human brain, and the findings were concerning, at the very least. Some of the most concerning data collected from the study actually reveals that a persons brain could shrink in size, as they are exposed to air pollution over a long period of time. This is a major concern, and now, reveals how much of a crisis dealing with air pollution really is.
The findings though, which were published in “Stroke”, the American Heart Association journal – aren’t anything that’s really new to the field. Many scientists have thought this for some time, and they’ve even had some data to back up the notion that air pollution can impact the human brain. However, this is the most telling data of any of the finds to this point. Another find in the study was that individuals were 46% more likely to have a silent stroke, if they had been exposed to a large amount of air pollution over a long period of time.
Lead author Elissa H. Wilker, Sc.D., pointed out that, “Long-term exposure to air pollution showed harmful effects on the brain in this study, even at low levels, particularly with older people and even those who are relatively healthy.” She went on to point out that, “The magnitude of association that we observed for brain volume was similar to approximately one year of brain aging.”
In this situation, the connection is clear – and it’s becoming increasingly important to deal with these things instead of letting them simply be, and assuming that in the long term things will just be fixed. Air pollution is the result of car exhaust, factories, and much more – and something that really has to be dealt with if we want to stop the long term negative side effects that are bound to continue popping up as time goes on, and more studies like this are funded.
