How can you stop your nose from being runny?

use lots of tissue papper.and blow your nose often.

You can also stop a runny nose by drinking lots of water. Don't rub it really hard because it might make your nose start to bleed, and also if you have rubbed your nose a lot, the next time you sneeze, it will start to sting. Blow your nose often and if you're allergic to dust, make sure there is nothing dusty or sandy in your room. It also sometimes helps if you go to sleep with 2 pillows, one on top of the other. I hope this works!

I found that if you blow your nose and wipe it dry, then immediately smear a little vaseline around your nose this will stop it being runny and will last up to an hour or until you feel the urge to blow again. It work especially well when struggling to get to sleep because of those sniffles!
