The Hidden Dangers of Poor Air Quality in Schools
Viruses and Solvents
Indoor air quality has emerged as one of the most critical issues in schools, influencing not only the health and productivity of students, but also affecting airborne disease transmission. In 2011, a study published in Environmental International¹ highlighted that elevated levels of indoor air pollutants increase the risk of health problems among schoolchildren. Markers, pens, and glues release volatile chemicals, including alcohols and other solvents, which can linger in the air for a long time. This leads to an increased risk of developing respiratory diseases such as asthma and allergies, negatively affecting learning outcomes.

How CO₂ Levels Can Make or Break Your Speech
Decreased Focus
High carbon dioxide concentrations can significantly impair the cognitive performance of both speaker and audience, compromising the presentation’s effectiveness. As CO₂ levels rise above 1000 parts per million, which can happen quickly in a crowded room, decision-making abilities, concentration, and memory recall decrease. The speaker has difficulty staying focused, forgetting key points and struggling to articulate ideas clearly. The audience finds it harder to pay attention, process information, or retain the content of the speech, cognitive effects that can undermine even the most well-prepared presentation.

1. Cutting Costs
At the heart of every comfortable indoor space lies an HVAC system, designed to keep a building’s temperature at a comfortable level year-round. When the space becomes too hot, they activate cooling mechanisms, and when it turns too cold, they provide warmth. Unfortunately, it is all too common for the building to be heating and cooling at the same time without anyone knowing about it, not even the people who are supposed to be optimizing and maintaining the system. The result is unnecessary energy usage, extra maintenance, and equipment failure.
