Why do some people bite their nails?
Is it stress? People who bottle-up everyday tension need a release valve – and for some it might be the frequent biting of their nails.
Another theory is that it is some kind of nutritional deficiency – in particular if the nails are bitten and swallowed.
It can be an unsightly habit and very hard to shake-off.
Why can’t they just stop?
Nail biting is an ‘unconscious’ activity – the person may not be aware they are doing it.
Nail-biters may also have a form of OCD (obsessive compulsive disorder).
Picture this…
Have you ever trimmed a shrub or bush in an attempt to make it even, only to find that your obsession with symmetry caused you to trim and trim until all you had left was an ugly miniature version?
Well, the same idea applies to some nail-biters. They continuously bite and pick their fingers for symmetry – thinking it makes the problem look a bit better, but ironically just making things worse in the end.
3 ideas for the biter:
1. Pay attention to “prime biting time” – Ex. Is it while watching TV, reading, driving, etc.?
2. Create a physical obstacle during those times – Ex. Wear a pair of gloves, sit on hands, etc.
3. Spend a lot of money on a manicure so biting becomes more painful (at least financially) than not biting.
