Ever wonder why our nose seems to leak like a faucet when we are sick?
Did you know that you produce 1 liter of mucus each day?
We swallow a quart of snot each day.
Why is snot so runny?
Snot is made up of 95 percent water, but also includes proteins (that give it elasticity), fats, carbohydrates and salt. Now thats a gooey situation!
Why is snot green?
Mucus or snot contains white blood cells, which have green-colored enzymes that destroy infection-causing viruses and bacteria. The dead white blood cells, along with the dead viruses, are removed in the mucus, making it look green.
Snot can also be a rainbow of colors: red, brown, yellow, clear or multi-colored because of what is in it, like blood, dirt/pollution or an infection.
Mucus is snot sharing with everyone. Help stop the spreading of germs by washing your hands and sneezing onto your sleeve!
