Does Air Quality Affect Life Expectancy? Find out!

To answer this question I have taken into consideration the reverse case i.e How many years are we losing to air pollution. According to World Health Organization (WHO), Air pollution is one of the greatest environmental and health risks faced by humans in the recent years. Air pollution takes a heavy toll on your life, Scientists have found that depending on the place you live and the concentration of pollution in the air of that place, there is a direct effect on your lifespan. Dirtier the air, shorter is your lifespan.

In China, the gritty air is reducing Chinese lifespan by more than 3 years, while in India lifespan of a person is reduced by 4 years.If are a Delhite, the figure drops down to a decade!In a case study by National Academy of Science Journal, a strong link was observed between the pollution data collected from 154 polluted cities and the mortality rate of 78 million people.

Now that you have gained a rough idea of impact of air pollution on lifespan, brace yourself for
some more FYIs.

What are the main air pollutants impacting the mortality rate of humans? Particulate matter known for their vicious effects on human health reduces average life expectancy to a large scale. PM 10 penetrates deep into your lungs causing fatal respiratory diseases. The safe limit of PM 10 is 20
micro-grams per cubic meter of air as recommended by WHO. With every 10 micro-grams per
cubic meter of PM 10 in the air, lifespan is reduced by 7 months. As measured by Air Quality Life Index tools, PM 2.5 is even more dangerous than PM 10. Ten micro-grams per cubic meter of PM 2.5 reduces lifespan by 1 year.

In developed countries like US increasing PM 2.5 level decreases lifespan in New York by
a month and in Los Angeles by 8 months.

Let me cite an example of a recent study conducted in China in 2013 to understand more about ‘airpocalypse’. The study showed that life expectancy was 5.5 years lower in the Chinese cities surrounded by Huai river.This result reflected the improving air quality due to a huge investment in renewable energy made by China.

So to conclude by comprehending the facts and figures, it is well understood how air pollution
directly affects your lifespan.

Life is precious and one should persevere and cherish it.
