Air pollution is a serious problem that seems to be getting worse, leading many people to install professional-grade air purifiers like the Airgle PurePal Plus AG850 to breathe easy at home. Despite the growing issue, a new study has found unhealthy air can be crossed off the list of possible reasons behind rheumatoid arthritis (RA).
Researchers have long believed that there could be a link between the form of arthritis, which is an autoimmune disease leading to inflammation of the joints, and air pollution. However, a new study may have debunked this idea.
Scientists from Brigham and Women's Hospital used the Nurses' Health Study, which has the medical records of more than 11.400 women from between 1976 and 2006, to look for RA incidents and a possible link to air pollution. A total of 858 women developed RA over the course of 30 years. Researchers used these participants' mailing addresses to gauge how close they lived to places of high air pollution as well as other known pollutant-makers like power plants and highways.
Overall, the researchers found no solid link between RA and air pollution. However, the authors are quick to point out that more trials need to be conducted to verify the recent findings.
Even if there is no real connection to RA, air pollution can lead to a number of other serious medical conditions. Most recently, scientists from Rice University found cardiac arrest incidents went up on days when air pollution levels were above average.
