Air Quality Index

Have you noticed the air feeling thick or dusty sometimes? Or seen the haze in the morning? That’s what the Air Quality Index, or AQI, is all about. It’s just a number that tells us how clean or dirty the air is. Think of it as a score: the higher the number, the worse the air.

The AQI looks at things floating around in the air that can harm us like dust, smoke, tiny particles called PM2.5, ozone, and carbon monoxide. PM2.5 is the sneaky one. It’s so tiny it can go deep into your lungs, even into your blood. That’s why on some days, just breathing can feel a little risky.

The number also tells you how careful to should be. On a “good” day, you can go outside, jog, or let kids play freely. On a “moderate” day, some people, like older folks, kids, or anyone with asthma, might need to slow down. On a “poor” day, even healthy people can feel irritated eyes, scratchy throats, or a cough. And if the AQI is really bad, “severe,” it’s a warning. Staying indoors is smart, or at least wearing a mask if you must go out.

Checking the AQI each day is simple. You don’t need to understand every chemical or number. Just knowing the number can help you decide whether to open windows, go for a run, or take it easy. Little choices like this protect your lungs, your heart, and your overall health.
