* Structure: The area under the fingernails is a perfect environment for germs to accumulate because it's dark, moist, and relatively protected.
* Daily activities: Our hands touch countless surfaces throughout the day, picking up bacteria, viruses, and fungi. These germs can easily get trapped under the nails.
* Difficult to clean: It's often hard to thoroughly clean under the fingernails with regular handwashing.
Therefore, it's important to keep your fingernails trimmed and clean them regularly to prevent the spread of germs.
