Question

Anu has the tendency to breathe through her mouth. She keeps falling ill very often. Why do you think so?

Answer 1

Hii...Anu's habit of breathing through her mouth can be proved infectious as when we breath through nose the air gets moistened enough and the microorganisms are not able to pass in through nostrils that easily ...but if we breath through our mouth the air passing is totally impure and is not moistened enough so it can cause infections ..
