Please choose the correct ending to complete the given sentence: Health: [header] How to clear a stuffy nose [title] Take it easy when blowing your nose. [step] 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.

Ending1: This can help to clear your nose much faster. [substeps] Don't try to force a runny nose if you're congested-trying to get your nose full may cause more mucus to leak out. Ending2: Only blow your nose when it is running. [substeps] Blowing hard repeatedly will make the delicate membranes inside your nostrils get more inflamed, and can quickly lead to increased stuffiness. Ending3: In fact, blowing your nose heavily may induce a runny nose. [substeps] Instead, inhale and puff out as much air as you can. Ending4: [substeps] Besides working on your nose, dry out your face with a dry towel. Patting the clean tissue dry is particularly important in the event that your nose gets a thick, stuffy feeling.
