The American Lung Association estimates that people spend an average of what percentage of their time indoors at home or work?

The correct answer reflects the findings of the American Lung Association, which indicates that people typically spend around 65% of their time indoors, whether at home or at work. This high percentage underscores the importance of indoor air quality and the potential impact of air pollutants within enclosed spaces. Factors contributing to this statistic include factors such as modern lifestyle, urbanization, and the prevalent use of heating and cooling systems that often trap pollutants inside. Given that a significant portion of daily life occurs indoors, awareness of environmental conditions and health considerations becomes critical for both personal well-being and real estate practices, particularly when assessing property conditions and potential hazards. This information is particularly relevant to real estate professionals who need to understand the implications of indoor environments on potential buyers and renters.
