Exercise Can Outweigh Harmful Effects of Air Pollution

New research from the University of Copenhagen has found that the beneficial effects of exercise are more important for our health than the negative effects of air pollution, in relation to the risk of premature mortality. In other words, benefits of exercise outweigh the harmful effects of air pollution.

The study shows that despite the adverse effects of air pollution on health, air pollution should be not perceived as a barrier to exercise in urban areas. “Even for those living in the most polluted areas of Copenhagen, it is healthier to go for a run, a walk or to cycle to work than it is to stay inactive,” says Associate Professor Zorana Jovanovic Andersen from the Centre for Epidemiology and Screening at the University of Copenhagen.

The research results have been published in the journal Environmental Health Perspectives.

New NASA Map Shows Where You Are Most Likely to Die From Air Pollution

Each year millions of premature deaths world-wide result from various forms of air pollution. According to a new atmospheric pollution model designed by earth scientist Jason West of the University of North Carolina (data from which informs the NASA map shown above), some 2.1 million deaths per year result from just one particular form of atmospheric pollution: fine particulate matter, or PM2.5, which is emitted in car exhaust and smokestack effluent (and other industrial, domestic and natural  sources).

In general, these polluting particles in the atmosphere are referred to as aerosols (a mixture of particulate matter and air). Aerosols can take the form of suspended particulate matter (SPM), respirable suspended particles (RSP), which are particles with a diameter of 10 micrometers (microns) or less, and, the aforementioned fine PM2.5…the ’2.5′ refers to particles of 2.5 microns or less and may include ultrafine particles, and some forms of soot (such as black carbon soot from cooking stoves and biomass burning).
