How does poor air quality affect workers' health and productivity?

Poor air quality can affect people in very noticeable ways. Short-term issues include headaches, irritation of the eyes or throat, coughing, and that general “foggy” feeling where it’s hard to focus. Over time, regular exposure can contribute to asthma, allergies, respiratory illnesses, and more serious long-term conditions depending on the substance involved.

Productivity drops too. When people feel uncomfortable or tired, or they’re constantly dealing with irritation or odours, their concentration naturally slips. Teams also see more sick days and reduced morale. A workplace with clean air tends to feel calmer and more energising, which is why employers who take it seriously often see real improvements.
