Asthma symptoms are more severe as air pollution increases. For children, it is worse. The following describes some recent study on this subject. Based on this study, it is recommended that indoor air should be re-mediated with Austin Air Purifiers and the family of HealthMate Air Purifiers.
In February of 2009, Johns Hopkins University researchers reported results of indoor pollution on asthma sufferers. They concluded that increasing levels of indoor particulate matter pollution would increase the severity of asthma symptoms. Asthmatic children were monitored for 6 months to determine the impact of room particulate matter, comprised of an airborne mixture of solid particles and liquid droplets. They studied all shapes of particulates with a variety of chemical composition ranging from small (fine) to large (course) particles at 2.5 microns or less to 2.5-10 microns in diameter. Their goal was to quantify the impact of particulate penetration into the body’s respiratory system from normal household activities such as cooking and cleaning (dusting). Environmental monitoring equipment was placed into the children’s bedrooms where air was sampled many times over a 6-month period.
“We found that substantial increases in asthma symptoms were associated both with higher indoor concentrations of fine particles and with higher indoor concentrations of coarse particles,” said Meredith C. McCormack, MD, MHS, lead author of the study and an instructor with the Johns Hopkins School of Medicine.
When indoor coarse particle concentrations increased by 10 micrograms per cubic meter of air, there was a corresponding 6 percent increase in of days of coughing, wheezing, or chest tightness. With a fine particle concentration with a 10 ug/m3, there was a 7 percent increase in days of wheezing and a 4 percent increase in days on which rescue medication was needed. Ironically, the indoor fine particle pollution measures exceeded EPA outdoor pollution by two-fold.
“Improving indoor air quality and lowering indoor particulate matter concentrations may provide additional means of improving asthma health, especially for children living in inner cities,” added co-author, Patrick Breysse, PhD, a professor in the Johns Hopkins Bloomberg School of Public Health and co-director of the Center for Childhood Asthma in the Urban Environment. Improvements can be made with a high quality Austin Air purifier that is able to filter out both fine and coarse particle concentrations.
Direct links to indoor air pollution on asthma continue to be studied. If possible, use Austin Air Purifiers in your homes to ensure asthma prevention. This is particularly important for you and your family if you are located near industrial sites and larger cities.
