What is Asthma?
According to the NHS, “asthma is a common lung condition that causes occasional breathing difficulties.” It affects millions of people worldwide and is the most common chronic disease among children.
Can poor air quality cause asthma symptoms?
Low air quality can trigger asthma symptoms, with chemicals, dust mites, pollen, mould and pet dander typical pollutants found in the air. This is particularly true of indoor air, with the average person in western Europe spending 90% of their day indoors, breathing in air which is often up to five times more polluted than outdoor air. According to the BMJ, 90% of world population breathes air that exceeds WHO targets on particulate matter, highlighting the huge scale of the issue.
