Breathing constitutes our primal, instinctive action—a natural occurrence that transpires more than 20,000 times daily. When we contemplate the air we respire and its quality, our attention often gravitates toward outdoor air pollution, characterized by carbon monoxide and nitrogen oxides from vehicles and factories.

Nevertheless, as per the US Environmental Protection Agency, the air circulating within our homes can contain pollutants up to two to five times more harmful than the ambient air outdoors. While most individuals acknowledge the health concerns associated with outdoor air pollution, only a few recognize the potential hazards stemming from exposure to substandard indoor air quality, despite its capacity to yield comparable detrimental health outcomes.

Below, we’ll discuss how indoor air quality influences our well-being and gain insights into enhancing air quality inside our living spaces.

Impact on Physical Health

Indoor air pollution can cause significant health complications. Individuals exposed to indoor air pollutants for extended durations are particularly susceptible to their adverse effects. This vulnerable population encompasses children, older adults, and people with chronic illnesses.

Indoor air pollution is primarily caused by sources that produce gases or particles. It can include building materials and air fresheners, which constantly release pollutants into the indoor environment. Other sources, such as wood-burning stoves and tobacco smoke, contribute significantly to indoor pollution. Moreover, asbestos, a naturally occurring mineral fiber commonly found in insulation, flooring, and roofing materials used in buildings erected before the 1980s, can pose a significant health hazard when released into the air. Inhalation of asbestos fibers can cause severe respiratory ailments.

In cases where individuals have been exposed to asbestos and developed asbestos-related diseases, there may be recourse through asbestos trust funds. Companies with significant asbestos liabilities established these trust funds to compensate victims of asbestos exposure.

As a result, asbestos trust fund payouts support those affected, covering medical expenses, lost wages, and other related costs. The compensation awarded varies depending on factors such as the severity of the illness, the individual’s level of exposure, and the specific criteria set by each trust fund.

Impact on Cognitive Function

Indoor air quality notably impacts cognitive function, influencing individuals’ mental processes and abilities. Numerous studies have revealed a link between poor indoor air quality and impaired cognitive performance, particularly in tasks requiring attention, memory, and decision-making.

Several factors contribute to this phenomenon. First and foremost, pollutants, such as volatile organic compounds (VOCs), mold spores, and particulate matter, can lead to direct physiological effects on the brain. Inhaling these pollutants can lead to oxidative stress and inflammation, which disrupt neural connections and reduce cognitive function.

Additionally, poor ventilation and a buildup of carbon dioxide (CO2) in enclosed spaces can restrict the amount of oxygen reaching the brain, impairing cognitive function. Reduced attention spans, weakened information processing, and compromised decision-making have all been linked to high CO2 concentrations.

Formaldehyde and benzene, two indoor air contaminants, have been connected to neurotoxic consequences. Prolonged exposure to these substances may contribute to severe ailments and impact cognitive function over time.

Impact on the Overall Comfort of the Home

Poor indoor air quality significantly impacts the comfort of individuals within indoor environments. When the air is contaminated with pollutants, it can create discomfort and unease. Unpleasant odors, stale air, and the presence of allergens can lead to a constant sense of dissatisfaction and reduced enjoyment of living or working spaces.

Moreover, excessive humidity or inadequate ventilation can result in a stuffy and oppressive atmosphere, making it difficult to find respite and relaxation indoors. This compromised comfort can affect overall well-being, causing irritability, restlessness, and a general feeling of discontentment. Monitoring and maintaining indoor air quality is crucial for developing a cozy atmosphere that encourages unwinding, productivity, and a general feeling of contentment.

How to Improve Indoor Air Quality?

If you’re willing to improve indoor air quality, adhering to the following measures will suffice:

  1. Ventilation: Ensure adequate ventilation by opening windows regularly to allow fresh outdoor air to circulate. And install exhaust fans in kitchens and bathrooms to remove pollutants generated during cooking or bathing.
  2. Indoor plants: Introduce indoor plants known for their air-purifying abilities, such as snake plants, peace lilies, or spider plants. These plants can help filter out certain pollutants and improve overall air quality.
  3. Minimize pollutant sources: Identify and minimize or eliminate sources of indoor pollutants. For instance, use natural cleaning products, avoid smoking indoors, limit the use of candles, and properly store chemicals and household solvents in well-ventilated areas.
  4. Regular and thorough cleaning: Clean your home regularly to reduce dust, animal dander, and other allergens. Use vacuum cleaners equipped with HEPA filters to prevent the recirculation of dust particles. Pay special attention to carpets, upholstery, and bedding, as they can harbor pollutants.
  5. Control moisture: Excessive moisture can promote the growth of mold and mildew, which negatively impacts indoor air quality. Use dehumidifiers to control humidity levels, fix leaks promptly, and ensure proper ventilation in areas prone to moisture, such as bathrooms and basements.
  6. Use air purifiers: Consider using high-efficiency particulate air (HEPA) filters or air purifiers to capture and remove airborne particles, allergens, and pollutants from the indoor air. Select those that are suitable for the size of the room or area where they will be used.
  7. Radon test: It’s a naturally occurring radioactive gas that can seep into buildings, potentially causing lung cancer. So, inspect your home for radon levels and take steps to mitigate any detected issues.

These practices can significantly improve indoor air quality and create a healthy living environment for yourself and your household.


Indoor air quality has far-reaching implications for our health, cognitive function, and overall comfort. The cruciality of maintaining and breathing clean air has been greatly emphasized after the pandemic. The awareness of the detrimental effects of indoor air pollution is vital, considering that we spend a significant amount of time indoors. Mitigating air pollution indoors is crucial to avoid developing health conditions such as cognitive function impairments and reduced comfort levels. Several measures can be implemented to improve indoor air quality, including proper ventilation, using air purifiers, minimizing pollutant sources, regular cleaning, controlling moisture levels, and introducing air-purifying indoor plants.
