The best thing you can do for your nose is to keep it clean and thin out the mucus. Nasal irrigation, steam, and saline sprays are great for this. These methods help remove some of the irritants causing more boogers. The moisture also helps loosen the crustiness, so you don’t damage the lining of your nose when picking or blowing it.

One scientist thinks it’s possible that boogers boost your immune system. Editor's Note: This article was originally published on October 17, 2015, and was last reviewed on June 23, 2022.
