Cleaning for health: The vital importance of indoor air quality

Our lungs serve as a direct link to our bloodstream, making the quality of the air we breathe a critical factor in our overall health and well-being. In our fast-paced modern world, we often overlook an essential aspect of our health – indoor air quality. The average person today spends much time indoors – much of that in their homes. When sleep is factored in, many of us are effectively spending about one-third of our day within our indoor environments. For those who work in offices, it can often feel like we live two-thirds of our lives inside four walls. This increasing indoor existence raises an important question: How clean is the air we breathe inside our homes and workplaces?

Understanding indoor air quality

Understanding Indoor Air Quality Indoor air quality (IAQ) refers to the condition of the air within and around buildings, particularly as it relates to the health and comfort of occupants. The Environmental Protection Agency (EPA) emphasises that indoor air can be more polluted than outdoor air, often significantly so. The implications of this can lead to a range of health issues, including respiratory problems, allergies, and other serious illnesses.

What contributes to indoor air pollution?

Indoor air pollution is generated by various sources, which can be categorised broadly into several categories:

1. Volatile Organic Compounds (VOCs): Commonly found in household products such as paints, cleaning agents, and air fresheners, VOCs can evaporate into the air and be inhaled, posing health risks in the short and long term.
2. Mould and Mildew: High humidity levels can lead to mould growth within homes, resulting in significant health risks, especially for individuals with asthma or compromised immune systems.
3. Particulate Matter: Dust, pet dander, and even tiny particles from combustion sources can enter the air we breathe and cause respiratory issues.
4. Radon: A naturally occurring gas that can seep into homes from the ground, radon is a leading cause of lung cancer among non-smokers.
5. Pesticides and Chemicals: These substances, often used for pest control in homes, can linger in the air and contribute to air quality degradation.
6. Human and pet skin scales and dander. This one is so underrated, but in our view it’s a big one. Not only are the micro pollutants that come from our skin scales and those of our parts hyperallergenic in their own right, but they feed dust mites and contribute to toxic levels of dust mite faeces and cast skins, which are in our view, a major contributor to dust allergies. And they are ubiquitous in indoor human living environments.

By understanding these factors, we can take deliberate steps to improve air quality in our homes and workplaces, ultimately leading to a healthier living environment.

The importance of maintaining clean indoor air

With the myriad of pollutants present in indoor environments, maintaining quality indoor air has become increasingly crucial. The repercussions of poor indoor air quality often go unnoticed until health issues arise. Here are several reasons why clean air is vital.

Reduces Health Risks: Clean air minimises the risk of various ailments, including respiratory diseases, headaches, fatigue, and eye irritation. Long-term exposure to poor air quality can also lead to more severe health conditions, including heart disease.

Enhances Productivity: For those working in office settings, air quality has a direct impact on cognitive performance. Studies have shown that cleaner air can lead to improved focus, creativity, and overall productivity.

Promotes Better Sleep: Air quality affects our sleep patterns. Clean air can help improve the quality of our sleep by reducing allergens and other irritants that can disrupt a restful night.

Supports mental well-being: There is growing evidence of the connection between air quality and mental health. Clean air can help alleviate anxiety and promote a sense of well-being.

Tips for improving indoor air quality

Improving indoor air quality doesn’t have to be complicated. Here are some practical tips you can implement to ensure cleaner air in your living and working spaces:

1. Ventilate Regularly: Engage in natural ventilation by opening windows and doors when weather permits. Airing out the space can help dilute indoor pollutants.
2. Use Air Purifiers: Invest in high-efficiency particulate air (HEPA) filters that can trap allergens, dust, and other toxins floating in the air. Make sure to choose an air purifier suitable for the size of your room.
3. Keep Spaces Clean: Regular vacuuming and dusting can help reduce the buildup of dust mites, pet dander, and other airborne particles. Opt for a vacuum with a HEPA filter for the best results.
4. Control Humidity Levels: Maintaining indoor humidity between 30-50% can mitigate mould growth and dust mites. Using dehumidifiers or air conditioners can help achieve this balance.
5. Choose Low-VOC Products: When purchasing paints, furnishings, or cleaning items, look for products labelled as low in VOCs or no-VOCs. This small change can significantly impact air quality.
6. Regular HVAC Maintenance: Ensure that your heating, ventilation, and air conditioning systems are regularly maintained and cleaned. Replacing filters and cleaning ducts can drastically improve air quality.
7. Houseplants: Some indoor plants can naturally purify the air by absorbing toxins. Consider incorporating plants like spider plants, snake plants, or peace lilies into your space.

The role of awareness and education

Increasing awareness about the importance of indoor air quality is essential. Community programs and educational campaigns can help inform the public about the sources and risks of indoor air pollution. Employers can also play a pivotal role in fostering a culture of health, ensuring that employees are educated about air quality and the importance of maintaining it in the workplace. Schools, too, should prioritise air quality, as children are particularly vulnerable to the effects of pollution. Educating the next generation about air quality can encourage lifelong habits of health and vigilance.

Research and studies on indoor air quality

Numerous studies have been conducted to assess indoor air quality, revealing concerning trends. For instance, a recent EPA study highlights that indoor air quality in many Sydney homes and workplaces is often compromised due to a lack of adequate ventilation and the presence of harmful pollutants. Research from the Harvard T.H. Chan School of Public Health demonstrated that improved air quality in office settings led to enhanced cognitive function among employees, thereby reinforcing the link between air quality and productivity. In conclusion, the quality of the air we breathe indoors cannot be overstated.

With a proactive approach to enhancing indoor air quality, we can take significant strides toward improving our health and well-being. Whether at home or in the workplace, making small changes can create a lasting impact on our lives. Remember, clean air equals better health; it’s time we prioritise our indoor environments just as much as we do the outside world. Through education, awareness, and thoughtful actions, we can ensure that the air we breathe contributes positively to our health rather than detracts from it.
