Air pollution is known to be detrimental to our lungs and heart, but recent findings suggest it may also negatively impact our metabolism.
A study conducted by the University of Zurich and Case Western Reserve University reveals that prolonged exposure to polluted air can damage the body's ability to control blood sugar, potentially increasing the risk of insulin resistance and type 2 diabetes.
Researchers focused on tiny particles in the air, known as PM2.5, which are small enough to be breathed deep into the lungs. These particles originate from sources such as car exhaust, smoke, and factory pollution.
To investigate the effects of PM2.5, scientists conducted an experiment on mice, dividing them into two groups: one exposed to clean, filtered air, and the other breathing air filled with PM2.5 for six hours a day, five days a week, over a period of 24 weeks.
