I have been invaded by the snot monster, and it was not the first time.
Have you ever wondered why your Snot (Mucus) becomes a chameleon and changes colours from green to yellow to brown when you have a cold, the flu or sinusitis?
Well being an Interior Designer I always have been fascinated with colours, so I did some research on the colour of snot, and this is what I came up with. What I thought was a mystery is no mystery at all
These snot colours are not caused by an infection but by your immune system which sends white blood cells called neutrophils to protect you against bacteria. These particular white blood cells contain a green coloured enzyme and when they become prolific they will colour your mucus (Snot), on the other hand they will prevent the bacteria from penetrating in your blood stream.
So the colour of your snot is not as bad as it looks, and we should all be grateful to the colourful Neutrophil in our immune system.
Sorry, I know it is not a very elegant topic, but I really had to find out why my mucus normally as clear as plexiglass transformed itself into these yucky colours.
