You may already be aware of the connection between traffic and other outdoor pollution and asthma symptoms.
Now, new research suggests that indoor pollution may also play a role. According to scientists at Johns Hopkins University, rising levels of particulate matter is responsible.
Findings published in the journal Environmental Health Perspectives draw a connection between the particulate matter in a childs bedroom and the severity of asthma symptoms.
“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 lead author Dr. Meredith C. McCormack.
In several cases, the air measured by the scientists contained levels of particle pollution that were twice as high as the Environmental Protection Agencys standards.
Particulate matter is made up of both solid particles and liquid droplets that contain different chemical components.
Some people take nutritional supplements to help ease their asthma symptoms. These supplements may include selenium and magnesium, among other nutrients.
