Children spend a large part of every weekday at school, so creating a healthy environment is paramount to their learning and general health. The Environmental Protection Agency (EPA) warns that indoor air is two to five times more polluted than outdoor air, which can cause detrimental side effects to sensitive populations. The most common allergens found in the air at schools are dust mites, pests, and mold. Children with allergic asthma can suffer from asthma attacks due to these contaminants.
Poor indoor air quality (IAQ) in school can contribute to an uncomfortable learning environment and lack of focus in students. More importantly, it can cause chronic health issues that result in missed school days.
Signs That Poor IAQ May Be Affecting Your Students’ Health
Parents are often the first to notice if their child is suffering from the effects of poor indoor air quality, but teachers have the advantage of being able to monitor multiple children. Be on the lookout for these signs that indicate poor IAQ in your school:
- Multiple students complain about asthma or allergy symptoms during certain times of the day or week.
- Students report feeling better when they leave the school but have symptoms again when they return.
- Your school has recently been renovated or refurnished.
- You or your school have recently introduced new or different materials or equipment.
- Your school started using new cleaning or pesticide products or practices.
- Your school allows smoking.
- Your classroom has adopted a new warm-blooded animal.
What Can Teachers do About Poor IAQ in Classrooms?
Teachers are often the first school employees to notice the effects of poor indoor air quality on their students. They should take their concerns to the school administration, who should bring in a licensed HVAC contractor to evaluate the school’s air quality and provide air cleaning and purifying solutions.
On a smaller scale, teachers can combat low IAQ in their classrooms by going through the following checklist provided by the EPA:
General Cleanliness in Classrooms
