Why PM2.5 particles is bad for our health

Most of us know by now that PM2.5 particles is bad for our health. But why?

Professor Guojun He from the Hong Kong University of Science and Technology (HKUST) explains that since PM2.5 particles are so small, they can penetrate into your lungs and blood system. They can flow through your body and into the heart and brain. For example, if someone has pre-existing respiratory or cardiovascular diseases, PM2.5 can trigger heart attack or stroke, among other things.

Your body has an inflammatory response to the particulate matter, which is what happens when something from outside your body goes into your system. And then the body tries to prevent it from doing harm, and that causes inflammation.
