ST. LOUIS, MO (KTVI) - Does your child suck their thumb, or perhaps bite their nails?  The initial instinct is to try to get them to stop this behavior but perhaps it's time to look at these habits a little differently because they may have some positive health effects in the long run.

Dr. Manoj Warrier is a SLUcare pediatric allergist at SSM Health Cardinal Glennon Children's Hospital explains a new study. There was a new long term study done on children who suck their thumb and bite their nails. It found that thumb-suckers and nail-biters were less likely to have positive allergic skin tests later in life.

We've always heard that thumb sucking and biting nails were bad. They led to dental issues and often represented a social stigma. But this study is saying that the germs on our hands are helping build our immune systems.

The doctor doesn't recommend that you encourage your kids to start biting their nails or sucking on their thumb, but the study is worth a read!
