Let’s face it, our bodies are pretty weird! Scientists study the body, but still we don’t know all of the wonders it holds. From muscles to tissues to hearts, there’s a lot left to learn about what makes us do what what we do. Here are 20 weird facts about the human body, and they might (figuratively) blow your mind!
20. You can use up to 200 muscles per step you take.
These muscles include the tibalis, gastrocnenmius, soleus, and more. You may not realize it, but as you walk, your body and its muscles are constantly working, putting the process in motion. Do you see now why it’s so important that you stretch your muscles, especially if you’re going to take a long walk or run?
19. Over 1 million mosquitos would have to suck your blood in order to remove every drop in your body.
That sounds like the plot of a horror movie, doesn’t it? Mosquitos love blood, but it isn’t possible for that many mosquitos to suck your blod all at once! This is the amount of insects required for the average human. Remember this when you forget to put on mosquito spray!
18. Your nose knows it all!
Your nose can remember up to 50,000 scents. Think about how you can recognize certain scents, like Mom’s fresh-baked cookies or the soft waft of vanilla in a bakery. That’s your nose at work.
17. When you sweat, the sweat itself doesn’t stink.
It’s when the sweat collides with the bacteria on your body that you then can detect a scent and odor. That’s why it’s so important to wash up after sweating, so the sweat doesn’t linger and create a foul smell.
16. You may know your fingerprints are unique, but what on your body has a unique print?
Your tongue! Don’t expect tongue prints to be a crime-sleuthing tool yet, but scientists have found that your tongue and your teeth are unique to you – even if you have an identical twin!
15. Your pinky finger represents 50% of your hand strength.
It may seem like a small fry compared to your other digits, but the pinky finger does a big job when it comes to grasping and lifting. It’s hard enough when you break a finger, but you may find that breaking a pinky finger renders your hand almost impossible to use.
14. Sorry, your tooth is one thing that can’t repair itself.
Your muscles, tissues, and ligaments can heal and repair themselves, but as for your tooth? Well, you’re a little bit out of luck if it breaks. Your repairman is the dentist. Just be careful with hard candy now, you hear?
13. When it comes to atom count, you have more than the stars in the galaxy.
An adult human is made up of 7 octillion atoms. A amount that is 7,000,000,000,000,000,000,000,000,000 to be precise. What’s more impressive, is that your atom count is more than the number of stars in the galaxy, which sits at 300 billion. Didn’t Moby sing “We are all made of stars?” – well, the sum of us is greater than the stars!
12. There’s gold in that blood!
Yes, there’s gold in your body. It’s a paltry amount, but it’s there. 0.2 milligrams of gold to be precise which means you’d need 40,000 people to share the gold in their blood to get enough to equal one gold piece.
11. You process information way faster than you can imagine.
It may seem like you’re reading something at a snail’s pace, but know that the human brain is capable of reading up to 1,000 words per minute. The more you read, the better your brain processes what it takes in.
10. You were born with your eyes, and they don’t change in size.
As you grow, other parts on your body grow. These include your ears, nose, and limbs. Your eyes, however, they stay the same.
9. It’s more than work to frown than smile.
You probably heard your mom “turn that frown upside down” or “it’s easier to smile than frown,” and well, she’s right! It takes 17 muscles to create a smile, and a whopping 43 to create a frown. Now sometimes you just want to frown, but think of this as just another wonder of the body.
8. Your body constantly replaces its red blood cells.
Your body goes through a process where it replaces your red blood cells every 7 days. Not only that, it’s not just in small groups either, because your body actually replaces half of its red blood cells during this time.
7. Unless you dust and vacuum regularly, there are pieces of your body on your carpet, bed and surroundings.
That’s because the human body loses about 1 million skin cells every day. This is one reason you’re supposed to replace your mattress every eight years as well – can you imagine having all those dead pieces of skin hanging around? This thought should make you want to dust and vacuum immediately.
6. If you can’t turn off your brain at night, sometimes it’s your anxiety, and sometimes it’s just science.
Your brain can be much more active at night than at the day, and it also thinks more at night. Maybe that’s why some of your best ideas and work can come at night! Your brain is also plenty active at night.
5. Your eyes are better and sharper than any camera.
Your eye processes images at the equivalent of 576 megapixels. Can you imagine how much that camera would actually cost?
4. On average, humans eat about 7,000 times their weight in food.
Think about everything you ate today. Now think about how much you’ll eat over a lifetime. That’s a lot of food!
3. Your body is warm, warm enough to boil half a gallon of water.
In 30 minutes, your body can get warm enough to boil half a gallon of water. That’s your body heat at work, keeping you healthy and alive.
2. One blink of your eye uses over 200 muscles.
Each time you blink, you’re using as many muscles as you do when you take a step!
1. Your smell is just for you.
Every human body has a unique smell that’s just theirs. Except for twins, everyone has the same smell. This explains why cats and dogs are so keen to smell us, probably.
