The phenomenon associated with the buildup of toxic compounds and pollutants in an airtight space is known as "sick building syndrome." This condition arises when individuals experience health issues that can be linked to prolonged exposure to poor indoor air quality, often due to inadequate ventilation, chemical pollutants from materials, and biological contaminants, among other factors.

In such environments, the accumulation of volatile organic compounds (VOCs), mold, and other irritants can lead to a range of symptoms, including headaches, fatigue, and respiratory problems. The term specifically emphasizes the relationship between the physical characteristics of the building and the health effects experienced by its occupants, making it a critical topic in discussions about indoor environmental quality.
