Enhancing Indoor Air Quality for a Healthier Lifestyle

1. Temperature

The temperature within a building can significantly affect IAQ. Extreme temperatures can make the indoor environment uncomfortable and lead to health issues. Maintaining an optimal temperature is crucial for IAQ.

2. Relative Humidity

The level of humidity in the air is another critical factor. High humidity can promote the growth of mold and mildew, while low humidity can cause discomfort and health problems. Maintaining the right relative humidity level is vital.

3. Oxygen

Adequate oxygen levels are necessary for the well-being of building occupants. Poor ventilation and a lack of fresh air can result in decreased oxygen levels, leading to health issues.

4. Carbon Dioxide

Excessive carbon dioxide levels can indicate poor ventilation. It can lead to drowsiness, headaches, and decreased cognitive function. Monitoring and controlling carbon dioxide levels are essential for good IAQ.

5. Carbon Monoxide

Carbon monoxide is a colourless, odourless gas that can be life-threatening when present in high concentrations. It's essential to have effective ventilation and carbon monoxide detectors to prevent its buildup.

6. Other Pollutants

Several other pollutants can contribute to poor IAQ. These include:

a. Sulphur Dioxide

Sulphur dioxide can irritate the respiratory system and worsen pre-existing conditions. Monitoring this gas is vital for ensuring a healthy indoor environment.

b. Nitrogen Dioxide

Nitrogen dioxide can lead to respiratory problems and decreased lung function. Reducing its levels is crucial for better IAQ.

c. Particulate Matter

Airborne particles like dust and pollen can cause allergies and respiratory issues. Regular cleaning and air filtration are essential to combat this issue.

d. Formaldehyde

Formaldehyde, often found in building materials and furniture, can emit harmful fumes. It's essential to choose low-formaldehyde products and ensure proper ventilation.

e. Volatile Organic Compounds (VOCs)

VOCs can be emitted from various sources, including cleaning products and paints. They can lead to eye and respiratory irritation. Using low-VOC products and proper ventilation can mitigate this problem.

f. Total Bacterial Count

Bacteria in the indoor environment can lead to various health issues. Regular cleaning and sanitation are essential to control bacterial growth.

g. Coliforms

Coliform bacteria can indicate contamination of water sources, which can affect both drinking water and indoor air quality.

Understanding the factors that influence IAQ is essential for maintaining a healthy indoor environment. Let's delve into these factors and how they can impact the air we breathe.

Factors Affecting IAQ

IAQ is a comprehensive measure of the quality of air within indoor environments such as schools, organisations, operation theatres, laboratories, and more. It's not just about ensuring that the air is clean but also about maintaining conditions that promote health and comfort for the occupants.

What is IAQ?

When it comes to creating a healthier living and working environment, Indoor Air Quality (IAQ) plays a pivotal role. IAQ refers to the air quality within and around buildings and structures, and it directly impacts the well-being and comfort of those who inhabit these spaces.
