Air pollution has long been known to cause respiratory issues and increase the risk of cardiovascular problems, but new research suggests that the brain is not immune to the harmful effects of smog. A study conducted by the University of Southern California has determined that long-term exposure to air pollution may result in brain damage, according to AltTransport.
Researchers exposed lab rats to the chemicals commonly found in smog for 150 hours over the course of a week. This is the equivalent of three weeks of traveling on the highways in southern California. Experts were able to determine that the pollution caused inflammation in brain cells, which can cause learning difficulty and memory issues.
Individuals who want to improve the air quality in their living spaces and remove harmful pollutants may want to purchase an air purifier. A device with a HEPA filter can greatly reduce the amount of particles in the air that are known to cause lung irritation.
The IQAir HealthPro Plus air purifier has a HyperHEPA filter that can trap ultra-fine particles that are smaller than 0.3 microns in size. The product can be helpful for individuals who suffer from respiratory conditions such as asthma.
