In the hustle and bustle of Colorado life, our focus often gravitates toward external factors influencing our health. However, there’s a silent player in the equation—the air we breathe inside our homes. In this blog post, we’ll dive into the connection between indoor air quality (IAQ) and our overall health. From the microscopic particles lingering in the air to the unseen gases we inhale, the quality of indoor air plays a pivotal role in shaping our well-being.
Understanding Indoor Air Quality (IAQ) in Colorado
Indoor air quality encompasses the composition of air within buildings and structures, directly impacting the health and comfort of occupants. The air we breathe indoors can contain a myriad of pollutants, ranging from dust particles and volatile organic compounds (VOCs) to mold spores and pet dander.
How IAQ Affects Health
Respiratory Health:
Poor indoor air quality is linked to various respiratory issues. Particulate matter, such as dust and allergens, can irritate the respiratory system, leading to conditions like asthma and allergies. Individuals with pre-existing respiratory conditions are particularly vulnerable.
Cardiovascular Health:
Emerging research suggests a connection between indoor air pollution and cardiovascular health. Fine particulate matter and other pollutants can enter the bloodstream, potentially contributing to heart-related problems. Long-term exposure may increase the risk of cardiovascular diseases.
Allergies & Irritation of Eyes, Nose, and Throat:
Common indoor pollutants, including VOCs, can cause irritation to the eyes, nose, and throat, with symptoms such as itching, redness, congestion, and a scratchy throat. Prolonged exposure to these pollutants can exacerbate these symptoms and affect overall comfort. Additionally, indoor allergens, such as dust mites, mold, and pet dander, thrive in environments with poor air quality, leading to intensified symptoms for allergy sufferers, including sneezing, itching, and congestion, when exposed to these allergens indoors.
Impact on Cognitive Function:
Recent studies suggest a potential link between indoor air quality and cognitive function. Poor IAQ, with elevated levels of pollutants, has been associated with reduced cognitive abilities, including impaired decision-making and decreased productivity.
Common Indoor Pollutants and Their Health Impacts
Particulate Matter (PM):
Fine particles in the air, known as PM2.5 and PM10, can penetrate the respiratory system. PM2.5, in particular, is associated with adverse health effects, including aggravated asthma, decreased lung function, and an increased risk of respiratory and cardiovascular diseases.
Volatile Organic Compounds (VOCs):
Found in household products like paints, cleaning supplies, and furnishings, VOCs can contribute to indoor air pollution. Prolonged exposure may lead to headaches, dizziness, and respiratory irritation. Some VOCs are also classified as potential carcinogens.
Radon Gas:
Radon is a naturally occurring radioactive gas that can enter homes through the ground. Prolonged exposure to elevated radon levels is a known risk factor for lung cancer.
Improving Indoor Air Quality for Better Health
Effective Ventilation:
Ensure proper ventilation in your living spaces by regularly opening windows and doors to allow fresh air circulation. Consider using exhaust fans in areas prone to moisture, such as bathrooms and kitchens. ERV/HRV systems can assist in bringing fresh air into your home without the need to open windows, preventing untempered air from entering. These systems allow fresh air to be introduced into the home in a controlled manner, thereby boosting indoor air quality (IAQ).
Air Purifiers:
Invest in air purifiers with HEPA filters and/or high-level filters to capture and remove airborne particles. This is especially beneficial for individuals with allergies or respiratory conditions. While HEPA filters are effective, they can sometimes cause airflow issues. There are many options available for filtering airborne particles, including carbon filters, electronic air cleaners, and filters with higher MERV ratings. Some filters combine all these features in one compact package. Additionally, UV lights can be installed in the ductwork of your home to reduce specific airborne concerns, such as bacteria, viruses, and mold spores.
Reducing VOCs:
Choose low-VOC or VOC-free products, such as paints and cleaning supplies. Allow new furnishings or products to off-gas in well-ventilated areas before bringing them into your living space. Introduce an ERV/HRV, which could take the airborne VOCs and exhaust them outside of the home.
Maintaining Optimal Humidity
Control indoor humidity levels to prevent the growth of mold and dust mites. Aim for humidity levels between 30-50%. When considering adding a humidifier, one should consult an HVAC professional to determine the best product for your needs. In more humid climates, one can use dehumidifiers in damp areas as needed to help reduce the possibility of indoor growth.
Regular HVAC Maintenance:
Ensure that your heating, ventilation, and air conditioning (HVAC) system is well-maintained. Change air filters regularly and schedule professional inspections to keep the system operating efficiently and within the manufacturer’s specifications. A common problem due to lack of maintenance is the buildup of dirt, dust, and debris inside the HVAC components. When cleanliness is not taken into consideration during an inspection, this dirt, dust, and debris in the HVAC system can then get distributed throughout your home, potentially causing issues with key components inside the HVAC system.
