If it feels like you've had a permanent cold that refuses to evacuate your body this winter, here's a theory on why it's sticking around: you're making yourself more sick because you're blowing your nose wrong.

Now, keep in mind I'm not a doctor, but an actual doctor in London says that when you blow both nostrils into a tissue as hard as you can, you can shoot some of your mucus into your sinuses.  And that can lead to a sinus infection.

According to this doc, the right way to blow your nose is to gently blow each nostril individually.

He also says that neti pots don't really work  but that using a decongestant spray actually will make you feel better.  Decongestant sprays work about four to five times more effectively than decongestant tablets.
