Allergies are more than just a nuisance, they're also a serious problem - one in five people in the U.S. have either allergy or asthma symptoms, while 55 percent of all Americans test positive for one or more allergens, WebMD reports. A recent study has linked air pollution to a rise in allergy and asthma incidents and the reason behind the spike may surprise some.
Scientists from Stanford University discovered that airborne toxins called polycyclic aromatic hydrocarbons (PAHs) seem to prohibit protective cells in the body from signaling the immune system to react. PAHs were also found to over-active certain immune prohibitors that allow the allergens to run rampant in the body.
PAHs are sent into the air through burning fuel in diesel engines, wood fires and barbeque grills, according to Science News.
Asthma and allergies don't seem to be going away anytime soon, especially after the new information revealed in the recent study. Even though people may not be able to control the air they breath while outside, they do have the ability to improve the air quality in their homes. Installing professional-grade air purifiers like Airgle PurePal AG800 can help individuals breath easy while in the comfort of their personal dwellings.
