BAD AIR: 15 Places Around the Globe Where Exercise in Bad Air is Harmful

Yesterday we blogged about the poor air quality in India that is prematurely killing over 1 million people a year. Before that we looked at China's bad air, and what would happen if the U.S. EPA didn't exist (we would have the same problems as India and China). Today, we're spotlighting a story about research in the Journal of Preventive Medicine citing places around the world where the pollution is so bad, that it's detrimental to exercise outside.

Tipping point: revealing the cities where exercise does more harm than good

In at least 15 cities, air pollution has now become so bad that the danger to health of just 30 minutes of cycling each way outweighs the benefits of exercise altogether, according to new research
 
In cities such as Allahabad in India, or Zabol in Iran, the long-term damage from inhaling fine particulates could outweigh the usual health gains of cycling after just 30 minutes. In Riyadh, Saudi Arabia, this tipping point happens after just 45 minutes a day cycling along busy roads. In Delhi or the Chinese city of Xingtai, meanwhile, residents pass what the researchers call the “breakeven point” after an hour. Other exercise with the same intensity as cycling – such as slow jogging – would have the same effect.

“If you are beyond the breakeven point, you may be doing yourself more harm than good,” said Audrey de Nazelle, a lecturer in air pollution management at Imperial College’s Centre for Environmental Policy, and one of the authors of the report.

The study, originally published in the journal Preventive Medicine before the World Health Organization’s latest global estimates, modelled the health effects of active travel and of air pollution. They measured air quality through average annual levels of PM2.5s, the tiny pollutant particles that can embed themselves deep in the lungs. This type of air pollution can occur naturally – from dust storms or forest fires, for example – but is mainly created by motor vehicles and manufacturing.

Countries include: China, India, Qatar, Bangladesh, Kuwait, Iraq, Pakistan, Nigeria, Saudi Arabia, Iran, Uganda. 
  
Breathing polluted air has been linked to infections including pneumonia, ischemic heart disease, stroke and some cancers. The Institute for Health Metrics and Evaluation’s Global Burden of Disease study ranks it among the top risk factors for loss of health.

Gift/Memorial Suggestions

Several of our friends have lost loved ones (human and pets) and we found that one of the best ways to honor their memory is to give to an animal charity.
What better way to recognize a life of love, than by giving another life a chance for love?
We donate to many animal rescues, but because we volunteer with
DC Weimaraner Rescue and Coast-to-Coast Dachshund Rescue, those are our 2 favorites.
Consider giving the chance of life to a dog or cat.
