Sick Building Syndrome: How Poor Indoor Air Quality Affects Your Well-being

Updated: Aug 23, 2023

In an age where most of us spend a significant portion of our lives indoors, the quality of the air we breathe within buildings has a profound impact on our health and well-being. Sick Building Syndrome (SBS) is a term used to describe a range of symptoms experienced by occupants of a building, typically linked to poor indoor air quality. In this blog, we'll delve into what Sick Building Syndrome is, its causes, symptoms, and ways to combat it to ensure a healthier indoor environment.

What is Sick Building Syndrome?

Sick Building Syndrome refers to a situation where occupants of a building experience a range of discomforting symptoms that seem to be linked to their time spent inside. These symptoms can vary widely and may include headaches, fatigue, dizziness, eye irritation, nose/throat irritation, coughing, sneezing, and even difficulty concentrating. While the exact cause of SBS isn't always clear, poor indoor air quality is often a significant contributing factor.

What are the Causes of Sick Building Syndrome?

  1. Inadequate Ventilation: Insufficient fresh air exchange can lead to a buildup of indoor air pollutants, causing discomfort and health issues.

  2. Indoor Air Pollutants: Volatile Organic Compounds (VOCs), formaldehyde, dust, mold, pollen, and even chemicals from cleaning products can accumulate and contribute to SBS.

  3. Poor Maintenance: Improper upkeep of HVAC systems, filters, and building infrastructure can lead to the circulation of contaminated air.

  4. Office Equipment: Electronics and office machinery can release harmful chemicals and particles into the air, especially when not well-maintained.

  5. Temperature and Humidity: Extremes in temperature and humidity can foster the growth of mold, bacteria, and other pollutants.

  6. Outdoor Pollution: Outdoor air pollutants can enter buildings and negatively impact indoor air quality.

Symptoms and Impact:

Sick Building Syndrome symptoms can be vague and easily attributed to other factors, leading to delayed recognition of the issue. Over time, prolonged exposure to poor indoor air quality can result in more serious health problems, exacerbate existing conditions (e.g., allergies, asthma), and even reduce productivity and cognitive function.

Prevention and Mitigation:

  1. Regular Maintenance: Ensure proper maintenance of HVAC systems, air filters, and building infrastructure to minimize the accumulation and circulation of pollutants.

  2. Ventilation: Adequate ventilation is essential. Increase fresh air exchange rates, especially in enclosed spaces.

  3. Air Purifiers: Consider using HEPA filters and air purifiers to capture particles and pollutants.

  4. Source Control: Minimize or eliminate sources of indoor pollutants such as tobacco smoke, strong cleaning agents, and volatile materials.

  5. Natural Light: Incorporate natural light and use non-toxic building materials to improve indoor air quality.

  6. Plants: Indoor plants can help purify the air by absorbing certain pollutants.

  7. Regular Cleaning: Routinely clean and dust surfaces to minimize the buildup of allergens and particles.

  8. Humidity Control: Maintain optimal indoor humidity levels to prevent mold growth.


Sick Building Syndrome serves as a reminder of the crucial link between indoor air quality and our overall well-being. As we spend more time indoors, understanding the potential risks and taking proactive measures to improve indoor air quality becomes paramount. By addressing the causes of SBS and adopting practices that promote healthy indoor environments, we can create spaces that foster productivity, comfort, and optimal health for all occupants. After all, the air we breathe within our buildings shouldn't compromise our well-being but instead contribute positively to our quality of life.
