What impact does poor indoor air quality have on occupant productivity?

Poor indoor air quality has a significant negative impact on both health and cognitive function, which in turn affects productivity. When the air quality is compromised—due to pollutants like dust, mold, volatile organic compounds, and carbon dioxide—occupants can experience a range of health issues, including respiratory problems, fatigue, and headaches.

Moreover, cognitive function is heavily influenced by the environment in which individuals work or reside. Research has shown that exposure to pollutants can lead to decreased attention, poorer concentration, slower reaction times, and impaired decision-making abilities. All these factors reduce the ability to perform tasks effectively and can lead to decreased productivity levels in workplaces and other settings.

In contrast to the other options, which suggest either an increase in productivity or no significant impact, the evidence clearly supports the conclusion that compromising indoor air quality adversely affects individuals' health and cognitive functions, aligning with the chosen answer. Additionally, stating that it only affects physical productivity overlooks the broader cognitive effects that can manifest as reduced overall productivity, considering that mental faculties are crucial for effective functioning in many work environments.
