Did you know that the health of more than half of the world’s population is at risk due to indoor air pollution? In 2012, a study published in the European Respiratory Journal helped shift the focus of air pollution’s impact on respiratory health from solely outdoor air pollution to indoor air pollution too. Asthma, bronchitis, chronic obstructive pulmonary disease (COPD) and other respiratory conditions are linked to indoor air pollution in both urban and rural settings.
Researchers found that indoor air pollution was responsible for 2.7% of the global burden of disease. This figure has steadily increased since the year of publication. This is not surprising as we spend approximately 90% of our time indoors where air pollutant levels can be two to five times higher than outdoors, according to the Environmental Protection Agency (EPA). Who would’ve thought that your home is often more polluted than your backyard?
The nexus between indoor and outdoor air pollution and lung health cannot be overstated. Thankfully, the entire month of October is dedicated to respiratory health.
What Is Healthy Lung Month?
Breathing in dirty air results in air pollutants penetrating deep into our lungs. Thus, the relationship between air pollution and lung health is clear. Exposure to air pollutants can trigger, worsen and provoke respiratory illnesses. Because October is Healthy Lung Month, it’s the perfect time for education regarding the dangers of air pollution and the importance of lung health.
Throughout history, lung health has captured the attention of healthcare workers, scientists and the media alike. Prominent lung diseases such as tuberculosis puzzled these communities for centuries. With an increasing number of afflicted individuals from all sorts of respiratory ailments and pervasive air pollution exposure, Healthy Lung Month is paramount today.
How Does Air Quality Affect Lung Health?
On average, you breathe roughly 25,000 times each day. When breathing, our lungs facilitate the circulation of oxygen-rich blood throughout our body in order to expel gaseous waste or carbon dioxide. How might this process be inhibited if we inhale air pollutants that we cannot naturally expel?
Nitrogen dioxide, particulate matter, formaldehyde and volatile organic compounds (VOCs), endotoxins, molds, phthalates and persistent organic pollutants contribute to indoor and outdoor air pollution. At any given time, you can inhale one or more of these irritants. Over time, causing irreparable harm to your respiratory system. While each air pollutant has varying effects on your respiratory health, one thing is for certain: your ability to breathe unobstructed is compromised.
Respiratory infections and diseases air pollution can cause or exacerbate include:
- Lung cancer
IAQ Solutions for Healthy Lung Month
1. Utilize Mechanical Ventilation
Before opening windows and doors for more fresh air, make sure to take a look at your local Air Quality Index (AQI) rating. Or, better yet, having a whole-home mechanical ventilation system allows you to turn to your HVAC system instead of natural ventilation when air quality is poor. Relying on open windows and doors when outdoor air pollutant levels are high will directly result in poorer indoor air quality.
2. Minimize Exposure to Air Pollutants
You can minimize your exposure to air pollutants indoors by minimzing pollutant emitting activities and exposure, such as:
- Avoiding wood-burning stoves, fireplaces and other wood-burning devices
- Reducing or eliminating the use of tobacco products in and around the home
- Using less toxic cleaning products without harmful chemicals and VOCs
- Walking and exercising outdoors when AQI values are low
These are just a handful of simple changes to make in your daily actions. Healthy Lung Month is the perfect time to take on easy lifestyle changes for better lung health!
3. Invest in a Whole-Home Air Purifier, Humidifier or Dehumidifier
Whole-home solutions ensure a healthier living space. A whole-home air purifier can remove a number of irritants from the air, protecting your lung health. They address particle pollution before it becomes unmanageable.
Humidifiers increase moisture levels in the air in your home, while dehumidifiers reduce moisture levels. Both humidity control solutions ensure your home remains in the ideal 40% to 60% humidity range. This ideal indoor relative humidity range helps defend against allergies, asthma and other respiratory illnesses.
4. Replace Air Filters Regularly
Dirty air filters significantly contribute to poor indoor air quality. Each time your HVAC system circulates air through a dirty or clogged filter, it captures fewer air pollutants, potentially spreading contaminants to every room in your home. This can cause a number of respiratory issues and exacerbate pre-existing health concerns. Furthermore, ensure that your home air filters have a MERV 11 rating at a minimum! The higher the rating, the better protected you are from allergens, VOCs and other air pollutants.
5. Install an Indoor Air Quality Monitor
In addition to providing basic climate information (temperature, humidity and air pressure), indoor air quality monitors provide information on various air pollutant levels. This will allow you to resolve air quality, HVAC system and home air filter issues before they worsen.
6. Consult an IAQ Expert
During Healthy Lung Month, consider consulting an IAQ-experienced home HVAC contractor to determine the best whole-home upgrade for your space. Each home is different, but the good news is that there are helpful solutions available for every home health issue.
