Fresh air prolongs the life of human

Scientists believe that the continuous decline in air pollution is associated with increased life span of people especially in rural areas.

According to a recent study in the United States, air pollution continues to decline between 2000 and 2007, although not at the same rates as that recorded in the 1980s. Despite this slow decline in the level of air pollution but it kept pace with the increasing life span of individuals.

Used the study, recently published in the journal Epidemiology, statements of 545 counties across the country, both urban and rural, the average decline in micro pollutants over eight years by 1.56 µg per cubic meter. In contrast, increased shelf life at a rate of 0.84.

Of course there are several other factors that contribute to increased rates of increase among individuals ages beside the clean air. The researchers took into account other factors such as declining smoking rates and per capita income and some other economic and health factors. Scientists have estimated that 18 percent of the increase in the life span of a person comes as a result of reduced air pollution.

Study author commented Dr. Francesca Dominic, Professor, school of public health at Harvard University, said: "this study emphasizes that even if we could reduce air pollution by fine particles slow rates, even if we have some effort to clean the air, the continuation of this work remains important, especially after this study demonstrated the added benefit of improved air quality on public health."
