As the new school year begins, parents and teachers are preparing to provide students with everything they need to learn best, from school materials to planning daily activities. However, there is one aspect that is often overlooked but fundamental to ensuring a productive year: the quality of air in classrooms.
Return to school: the importance of air quality in classrooms
Clean air reduces respiratory problems and days of absence
Air quality in classrooms is critical to the health and well-being of students. Diseases such as COVID-19, influenza, asthma and other respiratory conditions spread easily in environments with poor ventilation or high levels of pollution, causing absences that can compromise academic performance. Constantly monitoring ventilation, CO2 concentrations, allergens and particulate matter is of utmost importance to ensure a healthy environment for students and those who frequent school spaces. This allows immediate interventions to improve the air quality in the environment, reduce the presence of pathogens and prevent respiratory problems, thus ensuring greater school continuity and better academic results.
Improved mental health
Not only physical health, but also mental health can be affected by air quality. Exposure to air pollutants has been linked to a number of psychological disorders, including anxiety, depression and irritability. Monitoring and improving air quality in schools can reduce the incidence of these problems, creating an environment more conducive to students’ learning and psychological well-being.
Increased concentration and productivity
A school environment with poor ventilation and high levels of carbon dioxide can impair students’ ability to concentrate. Air quality monitoring can quickly detect these conditions, allowing immediate interventions such as increasing ventilation and opening windows or scheduling interventions, such as changing classrooms for different subjects with ventilation of the spaces. Studies have shown that improving classroom air quality can lead to significant increases in performance on tests and school activities, with students performing better due to increased concentration.
Enhancement of cognitive abilities
Exposure to poor quality air not only affects short-term performance, but can also have lasting effects on students’ cognitive abilities. Children exposed to high levels of air pollutants during brain development are at risk of having a lower intelligence quotient (IQ) than their peers. Constantly monitoring air quality in schools and homes with appropriate sensors can help prevent these long-term effects, ensuring optimal cognitive development.
Conclusion: air quality monitoring for a healthy school environment
Air quality in schools is a key element for student learning and well-being. Real-time air quality monitoring enables intervention when necessary to prevent the occurrence of unhealthy conditions in school spaces. Thanks to continuous measures, schools can guarantee safe and healthy spaces, reducing health risks and enhancing students’ cognitive abilities. Investing in air quality is investing in the future of new generations, guaranteeing them the best conditions to learn and grow.

FAQ: Frequently Asked Questions
Why is it important to monitor air quality in classrooms?
Air quality affects students’ health, well-being, and learning conditions. Insufficient ventilation can lead to the accumulation of CO₂, particulate matter, allergens, and other pollutants, increasing the risk of respiratory discomfort and potentially contributing to school absences. Continuous monitoring helps identify unsuitable conditions promptly and supports timely action to improve ventilation.
How can air quality affect students’ concentration?
In crowded and poorly ventilated classrooms, CO₂ levels can rise quickly. These conditions may reduce attention and concentration, making it more difficult for students to follow lessons and carry out cognitive tasks. Monitoring CO₂ helps assess the effectiveness of air exchange and determine when windows should be opened or ventilation increased.
Which parameters should be monitored to assess classroom air quality?
CO₂ alone does not provide a complete picture of indoor environmental quality. A more comprehensive assessment should include CO₂, particulate matter, volatile organic compounds, air temperature, and relative humidity. Monitoring these parameters together helps evaluate both air quality and the thermo-hygrometric conditions that influence students’ well-being.
Why is continuous monitoring preferable to occasional measurements?
Classroom conditions change throughout the day depending on occupancy, lesson duration, ventilation, and outdoor conditions. A single measurement may fail to capture the most critical periods. Continuous monitoring makes it possible to track trends, identify recurring problems, and define more effective ventilation strategies based on actual data.
