6 WHAT THE COLOUR OF YOUR SNOT SAYS ABOUT YOU

1 Clear

Boogers are made up of water and a protein called mucin, which together form a clear gelatinous substance, indicating you’re healthy.

2 White

When you’ve got a viral infection, clear mucin builds in the sinuses, and may turn a milky white colour.

3 Yellow/green

If your snot’s turned green or yellow it’s a sure sign you’re developing a cold. This colour comes from the build up of dead white blood cells used to fight infection.

4 Brown/orange

Blowing your nose and seeing brown or orange might have you concerned, but it’s likely just dried blood.

5 Black

Inhaling pollutants such as smoke or dust could result in some black snot, but it may also be a sign of a fungal infection.
