What is belly button lint?

For many years, people have wondered why the belly button lint appears. According to a 2001 study conducted by Dr. Karl Kruszelnicki of the University of Sydney, Australia, it was established that the navel lint comprises of stray fibres from a person’s clothing, which have combined with body hair, and dead skin cells.

The study also established that contrary to popular belief, the lint found in the navel comes from the person’s underwear and not from the tops or shirts as many people believed.

The fibres found in the navel move from the underwear to the belly button through the friction generated by the body hair against the underwear.

Where does belly button lint come from?

After conducting three years of navel lint research, a chemist (Georg Steinhauser) was able to discover the origins of the navel lint.

The research involved studying over five hundred pieced of fluff that were obtained from his belly button. After conducting chemical analysis on the fluff pieces, he established that the lint was made up of cotton derived from clothing.

The cotton in the navel had been wrapped using sweat, flecks of dead skin, dust, and fat.

What causes belly button lint?

Lint can be described as the small bits of dust and fiber, which accumulate around your clothes, and which often end up in your navel.

While conducting his research on navel lint, Steinhauser discovered a kind of body hair, which appeared to trap the lint pieces from the clothes, and once there trapped, the pieces were pushed towards the navel.

The hair had two factors, which led him to make this particular conclusion. Firstly, the hairs that were located appeared to have tiny scales, which acted like hooks, and which latched onto the lint and fibres found on the shirts.

Secondly, the hairs were seen to grow in a kind of circular pattern around the navel area, and this is what led to the collection of all the captured lint around the navel region.

To test his ideas, the chemist shaved the belly button area, and he was able to notice that the lint no longer gathered in this region. However, when the hair grew back, the same problem was experienced.

How does lint get in your belly button?

The question on how lint gets into the belly button can be answered by taking a look at the different types of belly buttons that are in existent.

People with bulbous belly buttons will often be fluff free. However, those who have the indented belly buttons can collect enough fibre to knit a good scarf, particularly if they are not very keen on cleaning this area.

According to Neil Goldberg, a dermatologist, it is a matter of complicated physics. You will find that the humidity and the heat from the umbilicus, when combined with your natural skin folds are able to trap skin oils, water, dust, as well as clothing fibre.

Why does belly button lint smell?

The belly button lint smells due to the fact that the area around the belly button is closed. As such, the area happens to be moist, and warm, and therefore gets to trap bacteria, as well as oil.
