Sadly, air pollution is a growing concern with levels reaching an all-time high in many cities around the world. Around 90% of city-dwellers are exposed to particulate matter (PM2.5) levels exceeding the World Health Organization’s (WHO) air quality safety guidelines. Traffic exhaust, industrial pollutants and naturally occurring allergens are all key contributors.
We now know that breathing polluted air can have a serious detrimental effect on our health, leading to lung cancer, respiratory illnesses and even cardiac arrest. In fact, the WHO estimates that urban air pollution causes around 1.3 million premature deaths per year. Growing evidence also indicates that the problem is particularly serious for children, pregnant women and the elderly.
What’s more, air pollution is not limited to the outdoors. Worrying levels of airborne toxins can also be found inside our homes, including viruses and mold spores. Breathing this air can have an immediate negative effect on our health and even more serious long-term consequences.
