Is it normal to eat boogers?
Mostly.Normal for most people
It’s common, especially in kids, and usually harmless. Adults do it too, though most people keep it private because it’s considered gross.
Your nose makes mucus to trap dust and other particles, and you swallow tiny amounts of it without noticing. Picking and eating boogers is also a pretty common childhood habit, and some adults still do it now and then.
It’s usually not a big deal, but it’s less likely to win you fans in public—and picking can irritate or scratch the inside of your nose. If you do it, washing your hands afterward is a good idea.
