Dirty air reduces life expectancy by more than a year

Air pollution reduces the global lifespan by more than one year, scientists say. According to a new study conducted by a group of leading environmental engineers and public health researchers, improving air quality can lead to a significant increase in life expectancy throughout the world.

This is the first time that data on air pollution and longevity have been studied together to reveal global differences in how they affect the overall life expectancy.

What do we breathe?

Scientists have studied the contamination of open air for particulate matter (PM) of less than 2.5 microns. These small particles can penetrate deep into the lungs, and inhalation of PM2.5 is associated with an increased risk of heart attacks, strokes, respiratory diseases and cancer. Pollution of PM2.5 comes from power plants, cars and trucks, fires, agriculture and industrial emissions.

Scientists compared the level of air pollution in different countries and life expectancy and came to the conclusion that dirty air has a big impact on life – shortens about a year of life.

In the context of other significant effects, negatively affecting the indicators of life, this is a lot.
