Air pollution: Low-cost portable air purifier can help protect your heart from pollutants
If you’re living in a highly polluted area, installing an air purifier
in your home might benefit your health in various forms. A good quality
air purifier can remove pollutants in the air, including bacteria,
viruses, volatile organic compounds, and odours. In fact, using air
purifier is a great way to reduce indoor air pollution. According to a
new study, using low-cost indoor air purifiers may help protect people
who are at risk from the adverse health effects of air pollution.
Air pollutants such as particulate matter irritates the eyes, nose, throat, and lungs, resulting in respiratory and cardiovascular diseases, and even premature death. Actually, air pollution now represents a major heart health risk. However, the study, found that three days of using a low-cost air purifier at home significantly lowered fine particulate matter exposure in urban seniors. It also significantly lowered their blood pressure, which is the leading cause of morbidity and mortality worldwide, researchers said.
“The results show that a simple practical intervention using inexpensive indoor air filtration units can help protect at-risk individuals from the adverse health effects of fine particulate matter air pollution,” said the study’s senior author.
In this randomized, double-blind study, which took place between fall 2014 and fall 2016, the researchers recruited forty seniors, of which ninety-five per cent of the participants were black, and all were non-smokers. Each participant experienced three different three-day scenarios - a sham air filter (an air filtration system without a filter), a low-efficiency air purifier system and a high-efficiency air purifier system.
During the study period, participants also carried out their normal business and were allowed to open windows and go outside as often as they wished. Participants, whose blood pressure was measured each day, wore personal air monitors to determine their personal air pollution exposure.
Over a three-day period, the team focused on reduced air pollutant exposure and lowered blood pressure as an indication of the portable air filters' potential to be cardio-protective. According to the author of the study, fine particulate matter exposure was reduced by 40 per cent, and systolic blood pressure was reduced by an average of 3.4 mm Hg (normal systolic blood pressure is considered less than 120 mm Hg; stage 1 hypertension begins at 130 and stage 2 at 140).
“The benefits were even more marked in obese individuals who had 6 to 10 mm Hg reduction in systolic blood pressure,” said the author. The researchers concluded that even a small investment could reap big benefits. Interestingly, the findings showed that high-efficiency air purifiers reduced pollutant exposure to a greater degree, but they didn't lower people's blood pressure more significantly than low-efficiency air purifiers, which are widely available for less than $70 apiece.
