Reddit Pocket Flipboard Email. A year's worth of belly button lint. David Burton Look in your belly button at the end of the day, and you might find a loosely packed tuft of soft lint.
How belly button lint forms Georg Steinhauser of the Vienna University of Technology is primarily an atomic chemist. Journal of Nutrition Steinhauser first arrived at this hypothesis by finding that of his friends, it was mostly people that had stomach hair who also typically found belly button lint.
Steinhauser As you can see, the vast majority of his lint balls weighed less than three milligrams. Delivered Fridays. Thanks for signing up! Check your inbox for a welcome email. Email required. By signing up, you agree to our Privacy Notice and European users agree to the data transfer policy.
Carla, Crewe, UK Fungal infections are pretty common in the folds of human skin. Maybe your navel is infested with the same mould that produces stilton cheese. Maybe it's the ammonia in my sweat Jamie Barking, Jersey well, as im not a philosopher of any sort, all i can say is that its a weird fact of life that 9 times out of 10 belly button fluff will be blue. The sky is blue. There are more particles of blue in the atmosphere which makes any colour of fluff appear blue to the eye.

Article Google Scholar Even if you shower every day, lint still collects Credit: Getty Images. Why so much belly button biodiversity? They draw an analogy to fish within an estuary. The permanent residents have adapted to the estuarine habitat, while other species that may briefly show up just aren't equipped to take up long-term residence.
Likewise, a disproportionate number of trees in any given rainforest are uniquely adapted to the tropics. Others may be able to grow in rainforest soil, but they can't establish a strong community.
While the sheer diversity makes it impossible to predict which types of bacteria might be found inside any individual human's belly button, what the researchers can do is predict which species are most frequent and which are rarer. So if your belly button doesn't routinely snag lint to form a ball of fuzzy fluff, fret not: your navel is still an exciting place.
