How to clear a stuffy nose
Take it easy when blowing your nose.
If your nose is stuffed up but not dripping, or mucus isn't coming out easily when you blow your nose, don't force it. Your impulse may be to blow your nose-hard-until you expel some mucus, but it's best if you leave the tissues alone.
Only blow your nose when it is running. Blowing hard repeatedly will make the delicate membranes inside your nostrils get more inflamed, and can quickly lead to increased stuffiness.
