Air Pollution, Brain Aging Link Found
There is research that demonstrates a clear link between air pollution and accelerated brain aging. This link may account for some of the otherwise unexplainable symptoms that are associated with air pollution exposure, and it highlights the need for air purifiers in living environments, especially those occupied by the very young and the very old.
This 2012 study concluded that significant levels of air pollution could accelerate cognitive decline, or brain aging, particularly among the elderly. This study by a team of researchers from the Davis School of Gerontology at the University of Southern California included more than 15,000 people over 50 years old, and it gave each a brain aging test score and then assigned it an air pollution concentration level based on where the person lived. The results showed that people living in the areas of highest pollution concentration had experienced brain aging three years faster than the test subjects living in the areas of lowest pollution concentration.
An important factor is that this research does not stand alone; in fact, it resonated with a distinct study published by scientists at the Rush University Medical Center. That study found a link between cognitive decline and fine air pollution matter, and called for increased intervention through policies, regulation and funding for new technology. The Rush University study made a point of mentioning HEPA filtration because it is able to eliminate all of the fine pollution particles from indoor air that the studies correlated with advanced brain aging.
It is important to recognize that indoor air quality is often more severe due to higher concentration levels, and it is reasonable to conclude that most of the brain aging damage that was present in the test subjects occurred while they were in their homes.
Technological advancements have made HEPA air purifiers so accessible that there simply isn’t a good reason not to have one in the home or even the workplace. Such protection is particularly important for children since they have higher metabolic rates and consume more air than adults.
Outdoor air pollution will make its way inside our homes where it will become even more concentrated and dangerous. Opt for a portable air purifier that has both a true HEPA filter, to trap particles and allergens, and an activated carbon filter, to trap VOC's like chemicals, gases and odors. A true HEPA filter effectively captures 99.97 percent of all airborne particles down to 0.3 microns in size. The benefit of a HEPA air purifier is optimal air quality, and it can result in easier breathing and reduced symptoms for those who suffer from asthma and allergies too.
