What health issues can arise from poor indoor air quality?

The choice highlighting respiratory diseases and allergic reactions is accurate because poor indoor air quality can significantly impact health. When the air in indoor environments is contaminated with pollutants such as dust, mold, volatile organic compounds (VOCs), carbon monoxide, and particulate matter, it can lead to a range of health issues.

Individuals may experience respiratory problems, including asthma, chronic bronchitis, and other obstructive airway diseases, particularly if they have pre-existing conditions. Allergic reactions may also exacerbate due to indoor allergens like pet dander, pollen, or dust mites, which thrive in environments with inadequate ventilation.

Recognizing the health effects associated with poor indoor air quality is crucial for prevention and management; improving ventilation and reducing sources of pollution can significantly enhance the health and well-being of the occupants. The other options reflect positive health outcomes, which are typically not associated with poor air quality, emphasizing the contrast in outcomes resulting from such conditions.
