We often think of air pollution as an outdoor concern, problematic in big cities and places with lots of traffic. But what about the air we breathe indoors? How often do we consider the air within our homes, schools and offices may be detrimental to our health too?
According to the World Health Organisation, air pollution is “contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere.” Commonly, this makes us think of vehicle emissions, manufacturing, power generation and agriculture.
However, a recent study by the New Scientist sheds light on the hidden dangers of indoor air pollution and its adverse effects on our wellbeing. Who knew the air we take for granted while busy at work or at home watching TV can be as laden with pollutants and have as significant an impact on our health as taking the tube during rush hour in London? It’s a cause for concern, right?
So, what is indoor air pollution?
Indoor air pollution refers to the presence of harmful contaminants in the air we breathe within enclosed spaces. These pollutants can originate from various sources, including building materials, cleaning products, pesticides, volatile organic compounds (VOCs), cooking emissions, and even outdoor air brought indoors. This means things we’re surrounded by all day, every day are potentially making us sick.
The same New Scientist study emphasises that exposure to indoor air pollutants can have serious implications for our health, contributing to respiratory issues, allergies, asthma, cardiovascular problems, and even certain types of cancers. Worrying stuff.
Key Findings of the study suggest three major areas for concern.
Chemical Compounds
The study reveals that indoor air can contain a multitude of chemical compounds, some of which are known to be hazardous to human health. These include formaldehyde, benzene, toluene, and other VOCs released from furniture, carpets, paints, and household products.
Particulate Matter
Particles suspended in indoor air, such as dust, pollen, pet dander, and mould spores, can trigger allergies, worsen respiratory conditions, and cause irritation to the eyes, nose, and throat.
Combustion By-products
Indoor activities like cooking, smoking, or using poorly ventilated fuel-burning appliances release combustion by-products like carbon monoxide and nitrogen dioxide, which can have detrimental effects on respiratory health and overall wellbeing.
It makes for sober reading. Especially in light of our collective knowledge gap in understanding that what’s surrounding us and helping us to breathe, may also be slowly killing us. But there are steps we can take to improve indoor air quality and minimise our exposure to harmful pollutants.
By being aware of the potential sources of indoor pollutants and implementing preventive measures, we can create healthier indoor environments for ourselves and our loved ones. Prioritising clean indoor air should be an integral part of how we live.
Here’s how:
Ventilation
Ensure proper ventilation in your living and working spaces. Open windows when possible or use exhaust fans to remove stale air and introduce fresh outdoor air.
Indoor Plants
Certain houseplants, like spider plants, aloe vera, and peace lilies, have air-purifying qualities and can help remove toxins from the air.
Commit To Being Clean
Dust surfaces frequently and vacuum with a HEPA (high-efficiency particulate air) filter to reduce the presence of allergens and particulate matter.
Natural Cleaning Products
Opt for natural, eco-friendly cleaning products to minimise the use of harsh chemicals that can contribute to indoor air pollution.
Smoke-Free Environment
Avoid smoking indoors and discourage others from doing so. Second-hand smoke is a significant source of indoor air pollution.
Air Purifiers
Consider using air purifiers equipped with HEPA filters to trap and eliminate airborne pollutants.
Maintenance
Ensure regular maintenance of heating, ventilation, and air conditioning (HVAC) systems to prevent the build-up and circulation of pollutants.
Source Control
Select building materials, furniture, and household products that have low VOC emissions. Look for products with eco-label certifications.
Consider Supplemental Oxygen
Supplemental oxygen can provide temporary relief from the symptoms of indoor air pollution. And while it doesn’t address the root cause of the pollution, it can help alleviate some of the respiratory distress caused by exposure to pollutants.
Here’s how supplemental oxygen can help fight indoor air pollution
Increased Oxygen Levels
Indoor air pollution can reduce the amount of oxygen available in the air, leading to discomfort and breathing difficulties. Supplemental oxygen provides a higher concentration of oxygen, ensuring the body receives an adequate supply, which can help alleviate symptoms and improve breathing.
Improved Oxygen Saturation
Exposure to indoor pollutants can hinder the oxygen exchange process in the lungs, resulting in decreased oxygen saturation levels in the bloodstream. Supplemental oxygen can raise oxygen saturation levels, ensuring that vital organs receive the necessary oxygen to function properly.
Reduced Respiratory Stress
Pollutants in indoor air, such as fine particles and volatile compounds, can irritate the respiratory system and exacerbate existing respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD). Supplemental oxygen can help reduce respiratory stress and ease breathing difficulties, providing relief.
Enhanced Exercise Tolerance
People with respiratory conditions or compromised lung function may experience reduced exercise tolerance due to indoor air pollution. Supplemental oxygen can improve oxygen delivery to muscles and tissues, allowing you to engage in physical activities with greater ease and improved endurance.
It’s important to note that while supplemental oxygen can provide short-term relief, addressing the underlying causes of indoor air pollution is crucial for long-term health.
Identifying and eliminating the sources of pollution, improving ventilation, and using air purifiers are essential steps to ensure a healthier indoor environment.
