Which of the following conditions can worsen due to poor indoor air quality?

Poor indoor air quality can significantly impact individuals with asthma. When air quality is compromised, typically due to pollutants such as allergens, particulate matter, mold, and volatile organic compounds, it can trigger or exacerbate asthma symptoms. Exposure to these irritants can lead to inflammation of the respiratory system, increased mucus production, and heightened sensitivity to triggers. As a result, individuals may experience more frequent and severe asthma attacks, worsening their overall condition.

In contrast, while factors like skin hydration, energy efficiency of appliances, and home insulation quality may be affected by various environmental conditions, they do not have the direct, immediate health impacts that poor indoor air quality can have on respiratory conditions like asthma. Maintaining good indoor air quality is therefore crucial for the health and well-being of those who suffer from asthma.
