With the cold weather sticking around, it might feel like you\u2019ve got a runny nose most of the time. You\u2019re sniffling constantly, there\u2019s a drip in the back of your throat, or worse, it\u2019s coming out of your nose.\nWhat Makes Your Nose Run?\nBacteria and viruses are in the air all around us, and they go up your nose. The mucus in your nose and the cilia, those hair-like structures inside your nostrils, work together to trap germs and keep you from getting sick.\nYour nose produces more mucus to try to push out the germs that have made their way in. If the germs get past the mucus lining in your nose, you\u2019re likely to get sick. That\u2019s when your immune system kicks in even more, creating more snot.\nYou\u2019ll have a runny nose as long as it takes your immune system to fight off the illness, and then it\u2019ll decrease. When the mucus dries up, you get boogers. Although gross, those boogers can give you a hint as to what your immune system is doing and whether you\u2019re fighting off an illness that requires a trip to the doctor.\nWhat Can You Do About a Runny Nose?\nThere\u2019s not much you can do to stop your nose from running. Your body\u2019s working the way it should be. If the nasal drip is just too much, you can take an antihistamine, decongestant, or try different ways to clean your nose.\nUsing a neti pot or humidifier can help you clear out added pressure in your sinuses and wash away some of the germs trying to get past that mucus lining.\nRemember that while your nose is running, that mucus can spread sickness to other people. Be sure to wash your hands every time you blow or wipe your nose. And look out for other people with runny noses to make sure you don\u2019t catch their germs.
