Indoor air quality: An overlooked health concern in homes and workplaces
Indoor air quality (IAQ) is often underestimated, yet it has a major impact on our health and comfort. According to the Environmental Protection Agency (EPA), indoor air can be 2 to 5 times more polluted than outdoor air, and in some extreme cases, up to 100 times more. This is due to a buildup of pollutants such as volatile organic compounds (VOCs) from cleaning agents, paints, office equipment, and furniture; formaldehyde from construction materials, mold, dust mites, pet dander, and even radon gas, a known cause of lung cancer among non-smokers.
Both homes and workplaces can suffer from poor ventilation, especially in modern buildings designed to be energy-efficient but often too airtight. Without proper air circulation, contaminants accumulate and pose serious health risks. These include allergies, asthma, respiratory infections, and even long-term conditions like chronic obstructive pulmonary disease (COPD) and cardiovascular issues. Children are particularly vulnerable because they breathe more air relative to their body size.
In office settings, poor IAQ can lead to a range of symptoms known as Sick Building Syndrome (SBS), including headaches, fatigue, dizziness, and difficulty concentrating. This not only affects employee health but also reduces productivity and increases absenteeism. Devices like air conditioners and humidifiers, if not regularly cleaned, can further worsen the situation by circulating mold and bacteria.
Improving indoor air quality is essential in both residential and commercial spaces. Regular maintenance of HVAC systems, use of air purifiers, proper ventilation, and reducing the use of chemical-heavy products can all help create healthier indoor environments.
