Nails Facts for Kids Fact Number 1: The Part of The Nail That Is Visible to Us Is Actually Dead!

Our nails are made of dead cells. For this reason, it doesn’t hurt when we cut our fingernails and toenails. Similar to how it doesn’t hurt when we cut our hair.

The part of our nail that is under the skin is the only part of our nail that is actually alive. Blood flows to this part of the nail, which is the root of the nail, to help it grow. The white part on the bottom part of your nail is called a lunula.

Nails Facts for Kids Fact Number 2: Finger Nails Grow Slowly

Fingernails grow an average of 3.5 millilitres per month, but toenails grow at nearly half this rate. The fingernails on your dominant hand grow faster. Men’s fingernails grow faster than women’s nails. Fingernails grow faster in the summer than in the winter.

This is because your body takes in more Vitamin D during the Summer resulting in greater nail growth. Your thumbnail grows the slowest, while your middle fingernail grows the fastest.

Fingernail growth slows down as we age. According to the Guinness World Records, the longest fingernails in the world belong to Diana Armstrong, whose fingernails are 42 ft 10.4 inches in length!

Nails Facts for Kids Fact Number 4: The Main Purpose of Our Nails Is for Protection

Fingernails are for protecting not only the fingertips but also the surrounding soft tissue from any external injuries.

Our toenails also protect our toes from being damaged. The nails offer the first line of protection for our fingers and toes. The skin that surrounds your finger is the cuticle and it also serves a purpose.
