Also…what even is belly button lint?

Your belly button is kind of like a magnet for random bits of material in the area.

(One 2012 study inPLOS Onefound 2,368 types of bacteria in a sample of 60 peoples belly buttons.)

It all depends on your body.

Three main things determine how much belly button lint you collect.

One is the shape of your belly button.

The architecture of that indentation, Dr. Goldbach explains, creates a nice home for matter to accumulate.

Such superb hosts, those innies!

The deeper and wider your navel is, the more space available for fluff to amass.

The amount ofhairon your abdomen also influences your belly button lint.

Abdominal hair can create friction that rubs fibers off your clothing, Dr. Khetarpal explains.

It can also help channel those fibers toward your navel, Dr. Goldbach says.

(His lint specimens had an average weight of 1.82 milligrams if youre curious.

Thats about 1/500th the weight of a $1 bill.)

The thing is that belly button lint really is innocuous.
