Belly button fluff (or ‘lint’) seems to come from our underwear and trousers. Throughout the day, tiny bits of fabric get caught in the hairs beneath the belly button. Through mysterious forces not yet fully understood, these bits of lint travel up through the navel hairs, get mixed in with dead skin, fat hair and dust and come to rest in the belly button.
Various factors influence the amount and speed of navel fluff accumulation. People who are hairier (i.e. men) usually have a thicker ‘snail trail’ (that bit of hair beneath the belly button), allowing more lint to wriggle upwards. Overweight people also get more navel lint, owing to their deeper ‘innie’. Sadly, men are also more likely to be overweight than women.
If belly button fluff is causing you concern then here are some anti-fluff tips:
- Wear older clothes as they are less likely to shed lint.
- Shave your body hair, thus preventing lint from easily getting into the belly button
- Lose weight, so as to shorten the depth of your ‘innie’.
- Get a belly button piercing as this will effectively sweep away the fluff.
