6 Weird Facts About the Human Body
Everyone has their unique and interesting quirks that make them who they are. But even our bodies are always changing and adapting, and for the most part, we don’t think too much on how our body works.
Let’s take a second to learn a few interesting, yet weird facts about the human body you’ve probably never heard before. From the color of your eyes to the strength of your bones, these are some weird facts about the human body that will make you question everything.
6. Your Body Is Unique
It’s common knowledge that fingerprints are unique to each person, but did you know that isn’t the only trait that is specific to your own body? Along with your unique fingerprint, your tongue’s print is also unique.
This means the textures, surface lines, and patterns, like your finger, are another secure biometric marker. But that’s not all! Your eye color is another unique trait. While many of us have brown, green, blue, or even hazel eyes, the specific eye color that you have is only created for you. This is just another reason that proves you’re one in a billion!

5. You Have Strong Teeth
When you think of sharks, you might think of the terrifying creatures that swim in the water and chomp at prey. These predators are terrifying, and their teeth are one of the main reasons. Interestingly, though, human teeth are just as strong as shark teeth.
One of the many weird facts about the human body is the strength we don’t actually know we have. While shark teeth are composed of different materials, largely of fluorapatite, which is harder than material found in human teeth, hydroxyapatite, both teeth are similar in strength.

4. Only Humans Blush
Need another reason to prove that we’re special? Only humans blush. We all blush, whether it’s for mortifying or happy reasons, but it’s one of those weird facts about the human body that makes us question why only humans blush.
Research believes that blushing might have evolved to show sincerity or submission in social interactions, as it’s caused when a person becomes self-aware, either in an awkward situation or another. It’s believed that blushing proves authenticity and emotional depth, which is one of the reasons why humans are the only species that blush.
3. Your Body Lights Up
While it won’t help you when you’re in a dark room, one of the best weird facts about the human body is that our body lights up, just not enough for the human eye. According to studies, humans also have bioluminescence, which you might associate with deep-sea creatures like angler fish or jellyfish that have light.
But while the angler fish can light up a decent area, we aren’t so lucky. Unfortunately, the light we omit is around 1,000 times lower than the sensitivity of our naked eyes, leaving. So as you’re reading this, your body, through biochemical reactions within our cells, is glowing!

2. The Truth About Your Bones
If you get queasy about your bones, beware, as we’re about to confess the truth about what lies underneath all that skin and muscle. When you think of bones, you probably think of the solid white bones in movies and TV shows. But while those are dry and brittle, the living bones that are inside us right now are actually quite wet and even a bit soft.
This is necessary in order to absorb pressure, as they need to be a bit flexible. Like most parts of the body, bones have a network of blood vessels and nerves running through them, and they bleed when broken. In fact, up to one-third of the weight of a living bone is just water.
1. Brains Eat Themselves?
Hold on, what? Are we zombies? No, actually, your brain is just healthy! One of the many weird facts about the human body is that brains actively eat themselves. The human brain is one of the most complex structures nature has ever devised, which means there’s still so much that we don’t know.
But one thing we do know is that the brain removes “waste” or “trash”, which is known as the glymphatic system, where the brain essentially washes out the waste in the brain. And that doesn’t mean information, this means clearing out protein aggregates called amyloid which can be linked to neurological diseases such as Alzheimer’s.
