What colour is your snot? This is what it could mean

Mucus is important 이그니션 다운로드. This slimy substance lines your throat, lungs, nose, sinuses and mouth for protection and support. The moist film in your nose helps it to stay lubricated.

In fact, you produce up to one and a half litres (four to six cups) of mucus in a day!

What your nose debris says about you

Clear. This is normal. Your nasal tissues produce mucus that consists of water, protein, dissolved salts and anti-bodies.
