Boogers are made up of mucus that has collected particles of dust, pollen, bacteria, and other substances and drained into your nose, where exposure to the air has dried it.

Is it safe to eat your boogers?

Over 90% of adults pick their noses, and many people end up eating those boogers. But it turns out snacking on snot is a bad idea. Boogers trap invading viruses and bacteria before they can enter your body, so eating boogers might expose your system to these pathogens.

Do boogers have a purpose?

Boogers help keep you well

In addition to keeping the tissues beneath it from drying out, mucus helps catch viruses and other harmful particles and stop them from getting into your airways. Tiny hairs inside the nose called cilia move the mucus down toward the nostrils.
