Science Has Some Good News For Nail Biters!

If you are used to people slapping your hands away from your mouth or having that foul tasting polish applied to your nails this news will make you even more satisfied than that time you chewed off the entire top section of your nail in one go.

A recent New Zealand study has found that people who bite their nails and suck their thumbs are less likely to develop allergies.

Guess chewing your nails and exposing yourself to some germs really does strengthen your body’s immune system.
 
 
Lead researcher Professor Bob Hancox said childhood exposure to microbial organisms through thumb-sucking and nail-biting might alter immune function so that those children were less prone to developing allergies.

This supports the ‘hygiene hypothesis’, which suggests that children who grow up in extremely clean homes aren’t exposed to germs that help strengthen their immune system.

The study analysed data from the ongoing Dunedin Multidisciplinary Health And Development Study, which is comprised of 1,037 men and women born in Dunedin in 1972-1973. This is part of the documentary Why am I?
