This prevents germs from hiding under our nails. Germs are small organisms which we cannot see using our eyes, but can only be seen by an instrument called a microscope.
If we have dirty nails while eating, the germs can enter our bodies through the food and make us sick. Besides making us sick, long nails can hurt us or our friends.
They can cut and bring wounds on our bodies. For this reason, it is important to keep our fingernails short and clean.
Our parents or older sisters and brothers can help us to cut long nails using a nail cutter. Never try using a razorblade to cut your own nails, because for you can easily hurt yourself.
