Students attending schools in the UAE may be exposed to hidden pollutants, potentially compromising the quality of the air they breathe.

In a recent study, it was found that fluctuating humidity levels can encourage mould growth in schools, while poorly cleaned systems may lead to a build-up of volatile organic compounds (VOCs). These factors can pose significant risks, especially for children with pre-existing respiratory conditions such as asthma or allergic rhinitis.

The study, titled 'Take a Breath: Improving Indoor Air Quality', analyzed ten classrooms across Dubai and Sharjah, including those from both older and newer schools built between 1970 and 2021, and those located near coastal areas to evaluate the impact of humidity and salt conditions.

Children learn best in environments where they can breathe easily and feel well. Poor air quality can lead to a wide range of health and learning problems, including impaired concentration, memory, and decision-making, often causing headaches, fatigue, and difficulty focusing. It can also worsen asthma and allergies, increase the risk of cough, wheezing, sinus irritation, and bronchitis. Younger children, particularly those in early years and lower primary grades, tend to be the most affected.

To combat these issues, schools in the United Arab Emirates have implemented measures such as installing advanced ventilation systems to improve indoor air quality (IAQ) in classrooms. They are also using emissions-low and health-friendly materials in construction and incorporating greenery or green roofs to filter dust, pollutants, and CO2 from the air, thereby creating healthier environments for children. Additionally, efficient heating systems and energy-saving lighting are used to enhance air quality and comfort while reducing energy consumption.

Deepika Thapar Singh, CEO-Principal of Credence High School, stated that their school is equipped with a state-of-the-art VRF (Variable Refrigerant Flow) HVAC system, which is used for maintaining IAQ in educational environments. They strictly follow Dubai Municipality standards for ventilation, filtration, and routine servicing to ensure a healthy and safe atmosphere in every classroom.

Schools located near construction sites and busy roads face added risks, with children experiencing higher rates of allergies, asthma, and respiratory problems. Prolonged AC use, if not properly maintained, can circulate pollutants, dust, mould, and allergens inside classrooms.

Experts stressed that maintaining good air quality in schools is not just for physical health but also for academic performance and overall comfort. Researchers measured pollutant levels and tested five different solutions, with the report aiming to support better ventilation, maintenance, and air purification systems across schools in the Emirates. Doctors emphasised that these interventions are critical, as poor classroom air quality is more than a matter of comfort - it is a health concern with serious consequences.
