Why do we have boogers in our nose? – Tia, aged 6
Great question, Tia!
Boogers, snot, bogeys and boogies are the common names for dried nasal mucus. Our nasal mucus is normally a clear, runny substance. However, as it moves closer to the surface of our nose it loses moisture to the air, dries out, and starts to harden.
