Recent findings on consequences of air pollution on human health have strengthened the accusation that air pollution is directly linked with developing high blood pressure. Vehicle exhaust, coal burning and airborne dirt have both short term and long term effects on human health. 17 different studies were conducted on this regard and the results unanimously hint on the same direction. The studies were conducted on 328,000 people in all and about 108,000 of them had high blood pressure. The studies were conducted in Brazil, Canada, China, Denmark, Germany, Iran, Spain, Sweden, Taiwan and the United States
Study Author Tao Liu said “Our results demonstrated that air pollutants had both short-term and long-term effects on risks, It is urgent to take more actions to protect our environment and clean the air quality,” especially those with high blood pressure, should closely focus on the air quality every day, and try to avoid outdoor activities or wear filtered masks when air quality is poor,” .
According to researchers, air pollution contributes in developing temporary spikes in blood pressure. However in long term chronically high blood pressure isn’t avoidable either. The studies also stated that high blood pressure in a prominent reason of developing heart disease and stroke. Also High blood pressure is solely reasoned to be 17 percent of death globally.
Reasons of air pollution were identified as nitrogen oxide, sulfur dioxide, carbon monoxide, dust specks, dirt, smoke, and droplets of liquid. Short term exposure to pollution such as sulfur dioxide also bolsters the risk of the developing high blood pressure. The findings didn’t draw a detailed picture of how these elements are affecting people in developing high blood pressure. Earlier it was assumed that Ozon and Carbon monoxide were linked to higher blood pressure. However, this hasn’t been proved in these studies.
Dr. Gregg Fonarow, a professor of cardiology at the University of California, Los Angeles also stated that cleaner air is necessary for the betterment of human health. Dr. Gregg said “These findings suggest that strategies to effectively reduce exposure to air pollution may have cardiovascular benefits,” Fonarow recommended to stay indoor when the pollution is at high level. However, Liu also recommended for uses of air purifiers indoor.
