Having a cold can really put a damper on your daily life. One of the major symptoms of having a cold is a runny and/or stuffy nose, and believe it or not there is a right way and a wrong way to deal with all that leaky congestion. First off, you don't want to sniffle it back into your head, so you are going to need to blow your nose frequently.
According to Web MD, you don't want to blow your nose too hard because this can cause an earache. The best way to blow your nose is similar to how most people put their pants on in the morning, one side at a time. Let me be explicit here: Press a finger over one nostril, and then gently blow to clear the other side. Reverse this action as needed. Also, you should wash your hands after blowing your nose to help prevent spreading germs.
