Sucking Your Finger Or Biting Your Nails Has Something Good …

Thumb sucking or nail biting is one of the “vices” of many children that causes many parents to worry. In addition to possible health consequences such as tooth defects and phonation, or the risk of infection, there is a concern that it is a sign of psychological distress.

Still, within the bad there is also something positive … In a study published in the journal Pediatrics , children who are between 5 and 11 and who have these vices (one or both) are also those who have a lower risk of allergies (Related to the skin as skin-optic) .

This finding comes from an epidemiological study conducted with over 1,000 people in New Zealand. They were tracked from children (born between 1972 and 1973) to adulthood. The parents of these children were asked when the children were 5, 7, 9 and 11 years old to respond if the children were still using a pacifier or if they bit their nails or sucked their thumbs. Of all these children, nothing more or less than a third would bite their fingernails / suck their thumbs or use pacifiers in a habitual way.

At age 13 and at age 32 the study participants underwent a skin test to determine the most common types of allergies: allergy to mites, cat or dog hair, pollen and mold. And from this they drew this curious conclusion:

Parents who had reported that their children used pacifiers, sucked their thumbs or bit their nails were less likely to have atopic skin. Which is considered as a precursor sign of allergies. 38% had allergies. (I recommend reading  Atopic skin: tips you should follow ).

Parents of children who did not have these habits had children with more cases of skin allergies. 49% had allergies.

And between the two vices (put your fingers to the mouth or use pacifiers), the percentage was lower among those who sucked their finger or bit their nails than those who sucked pacifier. This difference was maintained even when the researchers controlled for other possible factors such as predisposition to their parents’ allergies, the presence of animals at home, or the socio-economic status of the family.

Of course, the results follow this pattern for allergic skin disorders but not for cases of asthma or rhinitis.

Malcolm Sears, one of the teachers who led the study warns that the data in this study are not for people to take the habit of keeping their fingers to their mouths but that we should not be alerted so much because our children do: Although we do not recommend encouraging such habits, they seem to have a positive side. “

Dummies at an advanced age:

Beware !, it is necessary to remember that this type of vices brings with it another series of problems like the ones that I mentioned at the beginning of the article … that I do not ignore to you something that to take into account. In fact, these habits are one of the causes of dental deformities, lip and even palate. And if the habit continues even in more advanced ages also they give problems in the jaws. So … nothing to catch this bad habit!

What’s more, when done consistently can lead to problems in speech and in many cases (especially in later ages) is the cause of oral infections and digestive system.

We always have to look at all the pros and cons and no matter how many appearances that appear to be positive we must always know what is bad that can happen…

It is not yet known why these results or if it is only a coincidence, although the hypothesis that the excess of hygiene increases the risk of allergies. The hypothesis of the study is that children who are exposed to microorganisms can strengthen their immune system more effectively than those who are not exposed.
