Educators should know the risks of having poor air
quality in the classroom. Poor air quality will affect
children's having long-term and short-term health
problems, absence, and learning performance. It car
also lead children to have health problems such as
respiratory infections, nausea, dizziness, and
headaches. Educators should try to improve the air
quality often. They can improve the air quality by
keeping their thermostat slightly low which would
be between 40% and 70%. High humidity causes mold,
and this leads to poor indoor air quality and allergic
reactions, low humidity reduces children's natural
mucus, and it fights against these health problems. Please shorten this
