It is common knowledge that breathing polluted air can affect both your lungs and your heart. Long term exposure to the tiny dust particles in the air can even lead to chronic health problems like respiratory issues, irritation of the airways, asthma, kidney issues and at times it can even cause cancer. But a new study suggests that breathing in polluted air can even lead to weight gain.

The study

As per a study published in the Journal of the Federation of American Societies for Experimental Biology, air pollution can have a major effect on our weight.

Researchers conducted this study on rats, during which they exposed a group of pregnant rats and their offsprings to a seriously polluted area for a few weeks, while the other groups of rats breathed fresh and filtered air. After 19 days it was found that the rats exposed to the polluted air faced the following problems:

-Their lungs were inflamed

-LDL cholesterol level spiked by 50 percent

-Insulin resistance level also surged

Apart from this, the rats exposed to extreme pollution also gained weight after eight weeks, even though both the groups of rats were fed the same food.

The verdict

It is believed that weight gain was caused due to inflammation.

Though this study was conducted on rats, the ill-effects of air pollution on human health cannot be denied. This can be another reason why you should reduce your exposure to air pollution. Use mask whenever you go out and buy a good air purifier for your house.                 — Times of India
