How Indoor Air Quality Impacts Your Health

We often think about pollution as an outdoor problem. But have you ever considered the air inside your home, office, or school?

The quality of this indoor air has a profound impact on our health, productivity, and general well-being.

In this blog post, we’ll delve into the importance of indoor air quality (IAQ), the health effects of poor IAQ, and how to enhance the air quality inside your buildings.

Understanding Indoor Air Quality

Indoor air quality, often abbreviated as IAQ, refers to the quality of air within and around buildings and structures, particularly as it relates to the health and comfort of occupants.


Unlike outdoor air, indoor air is often recycled, leading to a build-up of pollutants.

Common pollutants found in indoor air include dust, mould, pet dander, volatile organic compounds (VOCs) from paints and finishes, and radon, a naturally occurring radioactive gas.

The Sources of Indoor Air Pollution

The pollutants contaminating our indoor air come from various sources.

Household products and materials, such as cleaning agents, building materials, and carpets, can release harmful chemicals.

Combustion sources like tobacco smoke, cooking appliances, and heating devices also contribute to poor IAQ.

Outdoor pollution sources, like pollen and smog, can infiltrate our homes and offices, further compromising indoor air quality. Lastly, biological contaminants, including mould, dust mites, and pet dander, also play a significant role.

The Effects of Poor Indoor Air Quality on Health

Poor IAQ can lead to a host of health problems. Short-term effects include allergic reactions, headaches, fatigue, and dizziness. These symptoms often disappear once the individual is no longer exposed to the source of pollution.

However, long-term exposure can lead to more serious health concerns like respiratory diseases, heart disease, and even cancer.

Poor IAQ is also linked to “Sick Building Syndrome,” a condition where occupants of a building experience acute health effects that seem to be linked directly to the time spent in the building.

The Vulnerable Groups

Certain groups are more susceptible to the effects of poor indoor air quality.

This includes children, the elderly, individuals with pre-existing health conditions like asthma and allergies, and those with weakened immune systems.

Methods for Improving Indoor Air Quality

The good news is, you can take steps to improve your indoor air quality. Regular cleaning and maintenance can reduce dust and biological pollutants.

Ensuring proper ventilation, especially in areas like the kitchen and bathroom, can prevent the build-up of pollutants.

Consider the use of air purifiers and dehumidifiers, which can help reduce particles and control moisture, respectively.

Opting for low VOC products when painting or renovating can also make a big difference.

The Benefits of Good Indoor Air Quality

Improving indoor air quality has numerous benefits. From a health perspective, it can lead to reduced allergy symptoms, better respiratory health, and improved sleep.

It also contributes to increased productivity, thanks to improved concentration and reduced absenteeism.

In the long run, maintaining good indoor air quality can help lower the risk of chronic diseases.

Case Study: Impact of Improved Indoor Air Quality

Let’s consider a school in Delhi that implemented measures to improve indoor air quality.

They installed air purifiers in classrooms, used low VOC paints, and ensured proper ventilation.

Within months, they saw a significant reduction in student absenteeism due to health issues.

Teachers also reported improved concentration among students. This example underscores the critical importance of good indoor air quality.


The air inside our homes, offices, and schools is as important as the air outside.

Prioritizing indoor air quality can lead to improved health, productivity, and overall quality of life.
