What is the dirt in the belly button? Can you pick it out? The long-standing question has finally been solved

This article was reviewed by Tao Ning, PhD, Associate Professor at a National Institute

I believe that many people were young

I can't help but pick my belly button

At this time, the elderly in the family always say

"Don't pick it, or your stomach will leak air"

Although it sounds doubtful

But I dare not pick it again

So

What exactly is the belly button used for?

Can I pick it out?

Why do some people have protruding

Some people are concave?

Let’s watch together

Do you understand after reading this?

In fact, the belly button is an important link with the mother

When we were still fetuses

In the mother's body through the navel - umbilical cord - placenta

Absorb nutrients from the mother

After birth

The doctor will cut the umbilical cord

After the wound heals, the navel is formed.

To put it bluntly

It is the scar left by the umbilical cord falling off after birth.

Everyone has many different shapes of belly buttons.

Different

But there's something in there.

Looks dirty

So many people can't help but want to pick

In fact, it's no big deal if you just scratch it a few times

But don't use too much force

Or use some sharp tools such as ear picks

It is easy to get infection in the belly button

Cause physical discomfort

If you really want to

Must maintain

Gentle movements and clean hands
