A recent study has suggested that avoiding rush hour traffic would lead to less risk of developing heart ailments or prevents the worsening of any cardiovascular disease that exists. "There is now ample evidence that air pollution is associated with cardiovascular morbidity and mortality," said corresponding author Robert Storey from the University of Sheffield, Britain."It not only makes existing heart conditions worse but also contributes to development of the disease," Storey added.

Irrespective of the place where you stay, tiny air pollution particles in the air can lead to major problems to your heart. It could come from anything around such as traffic jam, factories, power generation, wildfires or even if you cook food with the help of a wooden stove.

When many pollutants combine together they give out more of toxicity and tends to have greater impact than that of individual pollutants. A simple example could be that of diesel exhausts combining with ozone. The combined effect is always greater than that of separate effect.

There always exists a two way interaction between the air pollution and other cardiovascular risk factors. Obese people and those with diabetes may be at higher risk of the cardiovascular effects of pollution, while air pollutants may exacerbate and instigate the development of risk factors such as high blood pressure and impaired insulin sensitivity.
