How many classes have you slept through? For myself, this number is scary to contemplate. No matter how close I am to the front of the room, how important the subject is, or how much I respect the teacher, I have fallen asleep in far too many classes! Why do students fight fatigue and inattention in classrooms?
Students can be tired for a myriad of reasons unrelated to school. Perhaps they stayed up too late the night before, have post-prandial fatigue, or are uninterested in the subject. But students also struggle with fatigue as well as respiratory illness because of poor IAQ in classrooms. There are approximately 55 million elementary and secondary students in schools in the U.S., as well as 7 million teachers and staff, so maintaining good IAQ is an essential responsibility.
