Sneezing when you have a cold doesn't help get rid of the cold any faster.
However when you do sneeze you get rid of germs and bacteria that is causing the cold virus.
So sneezing and getting rid of those germs is a good thing.
But your cold will still last for the week or 10 days even though you sneeze.
You might also sneeze for a week or so after the cold virus is gone.
Make sure to cover your nose when you sneeze and sneeze into a tissue, hanky or even your arm if needed and then wash your hands and arms afterwards.
Most cold viruses last for 7 to 10 days which is a week to almost 2 weeks.
However some strains of the cold virus may last up to 14 days which is 2 weeks.
If your cold virus lasts longer than 2 weeks then it could be more serious and you might want to see a doctor.
The reason you should see a doctor if the cold virus lasts longer than 2 weeks or seems to get worse is because in some cases a cold virus can lead to Pneumonia.
The Pneumonia can be a serious health issue which can kill you.
But most cold viruses are just annoying and not serious enough to need to see a doctor about.
Most times when I have a cold virus the cold virus lasts for 7 days but I've had a cold virus last 15 days before.
Just make sure to get plenty of rest, drink plenty of water, orange juice etc and the cold virus should be over within within a few weeks at most.
Sometimes you might get a cold virus soon after you get over one which is also normal.
