What percentage of their total time do most urban dwellers spend indoors?

Most urban dwellers spend a significant majority of their time indoors, typically in the range of 80 to 90%. This is due to a variety of factors including lifestyle, work environments, and urban living conditions. People in urban settings often live in apartments or houses with less outdoor space and tend to work in office buildings or commercial environments that contribute to this high percentage.

The indoor environment plays a crucial role in public health, as it can significantly affect physical and mental well-being. Understanding this aspect emphasizes the importance of ensuring safe and healthy indoor conditions. Given that urbanization has led to more people living in densely populated areas, this statistic reflects the reality of modern living and highlights the need for effective indoor air quality and sanitation measures.
