Human Body Facts | Science ... When we catch a cold, germs spread to our nose, throat and other air passages. Our body fights off the germs and produces a slimy mucus to get rid of them. Sneezing and coughing blows out the germs with the mucus. Sneezing stops the tickling in our nose for a short while.
