Research estimates indicate that a third or more of U.S. schools have mold, dust and other indoor air problems serious enough to provoke respiratory issues like asthma. One national survey of school nurses found that 40% knew of children and staff who had been adversely affected by indoor pollutants.
Studies suggest that, in addition to the known health problems, students also perform better in schools with healthier air. Symptoms can include itchy eyes, runny nose, coughing, headaches, fatigue, and memory problems and slowed thinking. What’s more, medications for conditions such as asthma and rhinitis can also make it difficult for children to do their best work.
According to CNN:
“Researchers and others who follow the issue say school air problems have probably been exacerbated in recent years by funding cutbacks that have resulted in less money for building upkeep and maintenance ... Children are particularly at risk because their bodies are still developing and they breathe in more air, pound for pound, than adults.”
