Air affects school performance
In spite of this, according to a comprehensive study conducted by the University of Burgos, Spanish schools for example, can fail in terms of comfort, quality of the environment and ventilation inside buildings. This study also notes that children spend five out of every six hours in areas where there is poor quality air and a lack of comfort, which directly affects their health as well as their performance in school.
Ensuring that environments of education centres are clean and safe is not only essential for those centres but also for protecting society as a whole.
Ventilation and contagion
According to the classroom ventilation guide published by CSIC (which is based on the Harvard University Guide), zero risk does not exist; however, the better the ventilation, the lower the risk of contagion. In indoor environments, suspended particulate matter (aerosols), susceptible to containing viruses, may accumulate. Diseases may be spread through exposure to this air. The risk of contagion can be reduced by reducing emissions and exposure.
