e v i v r u s d n a t Protec Don’t pick your nose! It’s better and safer to blow. Snot is often full of viruses and bacteria; you don’t want to get them on your fingers or spread them around.
What does snot say about you?
10
Black: a fungus! See a doctor!
Brown: there’s dirt up your nose
Red: your nose is bleeding
Green: bacterial infection
Yellow: you have a cold
White: inflamed nose lining
Normal snot is clear and runny. But when you’re ill, it can change colour.
S
not and phlegm act as powerful defenders, guarding the places where germs, dirt, dust, and other dangerous, irritating substances might enter the body. Mucus surrounds and captures all these ‘invaders’, forming extra– thick, sticky snot and phlegm that can be removed by coughing or blowing our nose. Mucus also carries white cells from our blood that fight harmful bacteria. And it protects the delicate inner surfaces of our respiratory system by stopping them from becoming rough, dry, scratched or cracked.
Oh dear, I don’t think snot is meant to be that colour!
