11 Important things to know about air quality

When you think of the effects of air quality issues, you might think of visible smog that forces people to wear masks and causes coughing. However, air quality has a lot more to it than these visible effects. Here are some air quality facts that may surprise you.

1. Air quality affects everyone

You don't need to live near a hotspot for pollution to feel the effects it has on air quality. Weather changes and atmosphere can carry air with poor air quality all across the globe. Even thousands of miles away, the air quality in one area has the potential to affect you.

2. Different pollutants contribute to air quality

There are three main forms of pollution that negatively impact air quality. Nitrogen dioxide, particulate matter, and ozone near the ground all pose risks to your health when you breathe them in. These pollutants trigger or exacerbate health problems for many people.

3. Air quality pollution causes certain symptoms

How can you know if the air quality in your area is affecting you? The symptoms of air quality issues typically include shortness of breath or irritation to the eyes, nose, and throat. If you have respiratory issues such as asthma, low air quality will make those issues worse. Poor air quality can even damage the cardiovascular system, including your heart. The longer you're exposed to low air quality, the worse the problems can become. Poor air quality doesn’t just impact physical health, it can also cause mental health to deteriorate. A 2017 study found exposure to higher levels of finer particulate matter is associated with higher levels of psychological distress.

4. Air quality matters because we breathe a lot of air

On average, an adult breathes over 2,000 gallons of air per day. That's a lot of air! If the air quality is low, all that breathing will quickly result in health problems. And with physical exertion, you breathe in even more air.

5. Poor air quality can be deadly

Over time, health-related air quality issues will grow. Long-term exposure can result in an early death: that's how serious air quality is.

6. Exercise can't protect you from poor air quality

When it comes to most health risks, more exercise is part of the solution. But when it comes to air quality, more exercise will only make things worse. Even if you work out indoors, indoor air can also be impacted by air quality concerns. However, an outdoor workout puts you the most at risk. When you exercise, you take faster, deeper breaths, which gets the pollution into your respiratory system even faster. Whether you work out because you want to, or you do physical activity for your job, getting exercise when the air quality is low can cause more harm than good.

7. Children are especially at risk from low air quality

You might think that children breathe less air than adults since they're smaller. But in truth, children actually breathe more than adults and tend to be more sensitive to air pollution. Because children are smaller, they have narrower air passages. This means it takes less inflammation to block the airways of a child. Children also often do more physical activity and spend more time playing outside than adults do. This outdoor time means the effects of a low air quality index build up even faster in kids. Plus, kids are more prone to asthma, which makes air quality effects even worse.

8. Seniors may also suffer from air quality issues

Seniors are another population that's especially vulnerable during an air quality alert. If seniors have existing heart or respiratory problems, that makes the risk even worse. However, in general, the health risks associated with old age become more threatening when air quality levels drop.

9. Low air quality damages the environment

Air quality doesn't just pose a risk to human health. These issues can also pose a risk to the environment and nature. Animals who breathe low-quality air can also suffer from respiratory and related issues. However, even airborne pollution that doesn't affect humans and animals can still impact the environment. Even crops can suffer, as rising ozone levels damage vegetation.

10. Air quality gets impacted by multiple sources

There is no one culprit for low air quality. Some air quality issues have natural causes, while others are man made. For example, volcanic eruptions can significantly damage air quality. However, burning fossil fuels, agriculture, manufacturing, and other human activities can also harm air quality.

11. Air quality awareness week happens every year

Not everyone is aware of all these air quality facts. However, each year in May, Air Quality Awareness week serves to call attention to important air pollution facts like these. Knowledge and research play an important role in the future of our air quality.
