Here's the reason it feels weird when you poke around inside your belly button

Belly buttons are really weird things, aren't they? They are so odd. They're one of those parts of our bodies, whether you have an 'innie' or an 'outie' (innie ftw), that you can't help but just find utterly bizarre. Obviously we all know the purpose of them lies with when we were tiny little humans living inside of our mothers' tummies, but that still doesn't stop them from being extremely odd and, like our toes, some people are afraid of them. But, while belly buttons are weird, what is even weirder, is when somebody decides to poke your belly button.

You know the feeling, when someone (most likely your partner, otherwise who are you hanging around with!?), decides to have a little root around in your belly button. You get that funny sensation in your groin, which makes you shudder a bit and is reminiscent of the feeling of when you really need to go to the toilet. But why does it happen? Why does it feel so strange when someone decides to have a rumble around in our belly? Well luckily for us, we now have the answer to this question.

"At the navel, you have the ability to stimulate not only the skin overlying the navel, but also the fibers of the inner lining of your abdomen," Dr. Christopher Hollingsworth of NYC Surgical Associates said.

"So, as you stick your finger into your belly button, it sends a signal from the deeper fibers that line your inner abdominal cavity to your spinal cord," Dr. Hollingsworth says. "Because your spinal cord at that level is also relaying signals from your bladder and urethra, it feels almost the same. You interpret this as discomfort in your bladder."

However, while we undoubtedly get the funny sensation when we, or someone else, touches us in our naval areas, the same can't be said for the surrounding parts of the body, but why? Thankfully, Hollingsworth has an explanation for this as well, check it out below:

"You will notice that if you push anywhere around the belly button, it won’t give you the same sensation because you aren’t hitting the deeper fibers behind the muscle layer," he says. "The internal lining of the abdominal cavity at your umbilicus (belly button) is called your parietal peritoneum. This structure is exquisitely sensitive and its sensory nerve fibers relay input back to the spinal cord at the same level as the nerves that relay sensation from your bladder and urethra."

So there you have it, when you take a root inside your belly button, or someone else does, you are stimulating the abdominal tissue that is near the part of your spine that tells your brain that it's time to go to the toilet. Now, I don't know about you, but for some reason I now have the urge to plop my finger right in my belly button, even though it is guaranteed to make my skin crawl.
