Which of the following is a common health concern associated with poor indoor air quality?

Respiratory illnesses are significantly associated with poor indoor air quality due to the presence of various pollutants and irritants found in indoor environments. Common contributors to indoor air quality issues include mold, dust, pollen, pet dander, volatile organic compounds (VOCs), and tobacco smoke.

When individuals are exposed to these airborne irritants, it can lead to a range of respiratory problems such as asthma, allergic reactions, and chronic obstructive pulmonary disease (COPD). Poor ventilation exacerbates these issues since contaminants can accumulate, leading to higher concentrations of harmful substances in the air, increasing the risk of developing or worsening respiratory conditions.

While skin irritation may occur due to certain indoor pollutants, it is not as directly linked to overall health concerns as respiratory issues are. Cardiovascular efficiency could be affected indirectly, but the primary health risks are more strongly related to respiratory health. Weight gain, although it can be influenced by various health factors, does not have a direct and common association with indoor air quality. Thus, respiratory illnesses are recognized as the predominant health concern stemming from poor indoor air quality.
